ELASHMAWY, Takatoshi UENO, Banana Flowers (Musa sp.: Musaceae): an Essential Source of Nectar for Honeybee During the Dearth Period in Egypt, Journal of Faculty of Agriculture, Kyushu University, 64, 1, 79-85, 2019.02, A nectar dearth is a period when nectar producing flowers are scarce, and the dearth can be devastat- ing for honeybee colonies. Provision or presence of alternative flowering plants is thus crucial to stable bee- keeping. The present study was carried out at two different locations in Egypt to evaluate the importance of banana flowers as a nectar source during the dearth period (August –October) for honeybees. The inves- tigation on nectar production and sugar content estimated that banana flowers produced a large amount of nectar with a relatively high sugar concentaration and that one feddan of banana plantation during 2016 and 2017 seasons produced 29.2 and 31.5 kg nectar, which contained 4.54 and 5.21 kg sugar. Thus, expected honey yields were 5.67 and 6.51 kg honey/feddan in 2016 and 2017, respectively. Field observations demon- strated that the honeybee Apis mellifera carnica frequently visited banana flowers, in particular, in the morning time and that nectar in uncovered banana flowers decreased in response to honeybee vists while nectar volume in covered flowers remained unchanged. The honeybee colonies in banana farms showed much higher flight activity (foraging and pollen collection) and productivity (stored pollen, brood rearing, bee population, queen rearing, royal jelly production and honey production) than those in control localities. We conclude that moving the apiaries to banana plantations during the dearth period can conserve the strength of honeybee colonies allowing good overwintering, and improve honey yield by 2.69 ± 0.1 kg/col- ony..

Youssef, Takatoshi Ueno, Infestation caused by the Agromyzid Leafminer Liriomyza trifolii of Bean Crops in Kafr EL-Shiekh, Egypt., Journal of Faculty of Agriculture, Kyushu University, 62, 2, 435-438, 2017.09, Dipteran leafminers of the family Agromyzidae are polyphagous pests that evoke a severe worldwide threat to various vegetable crops. In Egypt, legume yields have recently been reduced due to intensive infestations by the leafminers. In the present study, we examined the composition of dipteran leafminers in two main leguminous crops, i.e., broad bean and snap bean, and evaluated the damage caused by them, in Kafr EL-Shiekh, Egypt. Liriomyza trifolii was the major leafminer species abundantly found on both crops while Melanagromyza phaseoli was found only in snap bean field with low density. Liriomyza trifolii was detected throughout the growing season of bean plants, though the population and infestation levels were significantly low in snap bean. A higher level of infestation on broad bean suggested the presence of host plant preference in the leafminer. Precipitation appeared to affect the infestation level of the leafminer. We discuss the importance of leafminer management in bean fields in Egypt..

Dang Hoa Tran, Masami Takagi, Takatoshi Ueno, Efficacy of the extract from pongam leaves (Pongamia pinnata L.) against Spodoptera exigua (Hübner) and Spodoptera litura Fabricius (Lepidoptera: Noctuidae)., Journal of Faculty of Agriculture, Kyushu University, 62, 2, 439-443, 2017.09, The beet armyworm Spodoptera exigua (Hübner) and the tobacco armyworm Spodoptera litura Fabricius (Lepidoptera: Noctuidae) are economically important insect pests of a variety of crops primarily in tropical and subtropical regions. Conventional control of these pests usually depends on synthetic chemical insecticides. Botanical pesticides have recently been paid considerable attention as an environmentally friendly measure to manage various insect pests. The present study was carried out to determine the efficacy of a leaf extract from pongam tree Progamia pinnata L. against the two armyworms. The results showed that the acute lethal toxicity of pongam leaf extract was high against the two armyworm species; the LC50 values were 1.94 %, 1.52 % and 1.10 % at 24, 48 and 72 hours, respectively for S. litura whereas the values for S. exigua larvae were 3.18 %, 2.57 % and 1.89 % at 24, 48 and 72 hours, respectively. Our study also indicated that low concentrations of pongam leaf extract caused significant reductions of vitality of the armyworms; they took more time to mature during the larval stage. Taken together, the treatment with a pongam leaf extract can negatively affect the armyworm populations directly and indirectly, and thus cause a reduction of overall pest numbers in the next generation. Thus, the pongam leaf extract is a recommendable bio-pesticide to control the armyworms..

A field survey was made to explore the major parasitoids of L. chinensis leafminer in central Vietnam. An eulophid parasitoid, Neochrysocharis okazakii, comprised more than 95% of parasitoids reared from leafminer larvae collected in the onion field and 98.3% of leafminer parasitoids found during searches of onion plants. The mean number of female N. okazakii on plants was greater in onion fields with a higher density of L. chinensis, and, during searches, a greater proportion of N. okazakii was found on onion with more L. chinensis mines, suggesting density-dependent parasitoid aggregation. Melanized dead larvae of L. chinensis were more frequently found in onion fields with more parasitoids, demonstrating that melanized leafminers are a good indicator of parasitoid activity. Mean instant rate of host encounter by N. okazakii in the field was estimated as 0.077, and the likelihood of a parasitoid finding a host increased with host density. Taken together, these results show that N. okazakii is the major parasitoid of L. chinensis. Usefulness of this parasitoid in stone leek leafminer management is discussed..

25. Takatoshi Ueno, Flower-Visiting by the Invasive Hornet Vespa velutina nigrithorax (Hymenoptera: Vespidae), International Journal of Chemical, Environmental and Biological Sciences, 3, 444-448, 2015.12, The Asian hornet or yellow-legged hornet Vespa velutina nigrithorax has recently been recorded as an invasive insect evoking environmental, apicultural and medical problems. Many aspects of the ecology, behavior and life history remain unknown, however. The present study focuses on flower-visiting by the hornet in the field. The foraging behavior of V. velutina nigrithorax on and around blooming plants was observed in Tsushima Island, Japan and Busan City, South Korea. The field observations confirmed that the hornet fed on floral nectar of 27 plant species scattering among 15 families. Pollen feeding was not observed. In addition, it was frequently found that V. velutina nigrithorax flew and hovered around a patch of flowers to predate hymenopteran bees and dipteran flies. Hunting behavior was recorded on 20 plant species belonging to 10 families. Field observations and mark-recapture experiments suggested that V. velutina nigrithorax played a role in pollinating at least some plant species. Although numerous hornet workers were found visiting flowers in the public area such as the park, school, hospital and home garden, none of them showed aggressive behavior against humans. Thus, flower-visiting V. velutina nigrithorax away from the nest did not pose a threat or risk associated with hornet stings..

This represents a first record of the species from mainland Japan. The foundress of the colony might have been transported with ferry cargos from Korea or China. The nest measures 35 cm long and 24.5 cm wide including the envelope, consisting of three combs. The examination of the nest (cell size and pupal caste) indicated that all the combs were for the worker caste and that new queens had not yet been produced..

Kanako Ueno, Takatoshi Ueno, Host approaching behavior in a parasitoid wasp (Hymenoptera: Ichneumonidae) as influenced by physiological state and host type, Entomology, Ornithology & Herpetology, 10.4172/2161-0983.1000159, 4: 159, 2015.08, sent study highlighted the interactions of host type and physiological state (i.e., the number of mature eggs a female carries) in determining a parasitoid’s host-finding behavior, using the solitary endoparasitoid Itoplectis naranyae (Hymenoptera: Ichneumonidae). Females took much shorter time to approach and attack healthy hosts of high-value than empty hosts of no-value, discriminating between the host types from a short distance. Variance of the time was much greater for empty hosts. A striking difference was detected in the influence of physiological state on wasp behavior; females with greater egg loads approached an empty host more quickly in order to examine its suitability for oviposition whereas egg load effects were not found for healthy hosts. Thus, egg load was involved in variation of the host-finding behavior but its effects depended on host types. We discuss the adaptive significance of the context dependent effects of egg load on parasitoid behavior..

32. Hiroaki Kohmura, Hiroyuki Hirayama, Takatoshi Ueno, Diving Into The Water: Cues Related to the Decision-Making by an Egg Parasitoid Attacking Underwater Hosts, Ethology, 10.1111/eth.12326, 121, 2, 168-175, 2015.02, Although adult parasitoids spend a majority of their lives above ground, females of several species must search for their host in the water or on the soil. Adult parasitoids above ground can use a variety of sensory cues to detect their hosts from a distance. However, their sensory cues can be impaired from volatile chemicals, and their visual stimuli can be decreased while submerging or burrowing in the water of soil during their search for their hosts. Searching underwater or underground would incur high forag- ing costs, that is, time and energy consumption and increase risk of drown- ing. Therefore, to reduce such costs and increase searching efficiency, the decision on where to start submerging or burrowing for attacking hosts is important for parasitoids. Furthermore, there are no studies that have examined the cues of submerging or burrowing parasitoids on their exploit for the decision to attack their hosts. We have examined the cues used by the egg parasitoid Tiphodytes gerriphagus attacking underwater hosts. We compared the searching behaviors of T. gerriphagus among four oviposition site conditions. The four sites investigated were oviposition site with both host adult chemical residues and presence of eggs, with only the presence of eggs, with only the host adult chemical residues, and without any cue. Our results indicated that T. gerriphagus more frequently contacted and submerged at oviposition sites with the adult residues rather than at ovipo- sition sites without them. Nonetheless, the presence of underwater host eggs did not affect the host-searching behavior. This suggests that T. ger- riphagus decided to submerge at the oviposition site in response to the adult residues. Furthermore, our observation also suggested that T. gerriphagus has already detected that the adult residues might be volatile before con- tacting the oviposition site. Finally, we will discuss the exploitation pat- terns of host-searching cue by parasitoids that need to submerge from the context of its reliability and detectability problems..
33. Kouhei Matsushita, Kanako Ueno, Takatoshi Ueno, Physiological Parameters Reflecting Longevity of a Parasitoid Wasp (Hymenoptera: Ichneumonidae), International Journal of Chemical, Environmental & Biological Sciences, 2, 4, 201-205, 2014.12, Itoplectis naranyae is a common parasitoid wasp inhabiting rice paddies in most part of Asia and is a candidate of biological indicators to assess biodiversity and eco-friendly agricultural practice in rice paddies. Here, we examined physiological factors affecting the longevity of I. naranyae to investigate its basic biology. For this purpose, life expectancy of the male and female was assessed without food (=carbohydrate) provision. As expected, the parasitoid had a much shorter lifetime under food deprivation. Curiously, both forewing length and body weight were not significant indices reflecting the longevity of male and female I. naranyae. Therefore, individual differences in life expectancy under starvation are not simply predicted with body size. Body weight loss during the lifetime instead correlated positively with the longevity, regardless of the sexes. Thus, weight loss, rather than body size, reflects the longevity probably because it reflects nutritional storage available for sustaining the life of I. naranyae..

Takatoshi Ueno, Establishment of the Invasive Hornet Vespa velutina (Hymenoptera: Vespidae) in Japan, International Journal of Chemical, Environmental & Biological Sciences, 2, 4, 220-222, 2014.12, The Asian hornet Vespa velutina nigrithorax, most probably originated in China, has been pausing an ecological problem in Europe and Korea after its accidental introduction and the subsequent establishment during early 2000s. In 2012, an amateur entomologist collected the first specimen of the hornet in Tsushima Island, Japan, which suggested that V. velutina invaded into the country. Field survey was hence made in 2013 to investigate whether the hornet had been established in the island. The survey confirmed the establishment of V. velutina. Morphological examination of the specimens obtained from Tsushima Island determined that the velutina belonged to the subspecies nigrithorax and was well coincided with the specimens from southern China. Field observations also confirmed that the invaded hornet was frequently found predating Japanese honeybee Apis cerana japonica, an important pollinator native to the island. The invaded hornet was thought to be accidentally introduced from South Korea, where the hornet had been well established since its invasion..

Hiroki Itadani, Takatoshi Ueno, Chemically Mediated Mate Finding of the Polyphagous Solitary Parasitoid Itoplectis naranyae (Hymenoptera: Ichneumonidae), Annals of the Entomological Society of America, http://dx.doi.org/10.1603/AN12146, 107, 1, 288-294, 2014.01, Polyphagous solitary parasitoids have difficulty finding mates that can be widely dispersed because of their polyphagous natures. Males of polyphagous species are more likely to rely on compounds characteristic of the female or on sex pheromones to find mates. However, the mating biology of few polyphagous parasitoids has been studied and sex pheromones are known for only a few species of parasitoids altogether. Here we examined the mating biology of the polyphagous parasitoid Itoplectis naranyae Ashmead (Hymenoptera: Ichneumonidae), which attacks a variety of lepidopteran pupae. The existence and timing of emission of female sex pheromones and male response with age were studied in the laboratory. A field test was also conducted to confirm the attractiveness of newly emerged females to wild males over a distance. The results confirmed that volatile compounds are used in the sexual communication in I. naranyae. Females attracted males most strongly shortly after emergence; pupae and older females were much less attractive. Older (30-d-old) males were most responsive to female sex pheromones. Males with prior experience with females responded more strongly than naïve males. The field test showed that traps containing virgin females attracted wild males. These results showed that this solitary polyphagous species uses volatile compounds to find scattered mates at close and moderate ranges. The existence of chemically mediated mate finding suggests that sex pheromone traps may be useful in management of I. naranyae as a biological control agent..

Takatoshi Ueno, Insect natural enemies as bioindicators in rice paddies, CNU Journal of Agricultural Science, http://dx.doi.org/10.7744/cnujas.2012.39.4.587, 39, 587-595, 2012.12, In Asia, including Japan and Korea, rice paddies occupy the largest cultivated area in agricultural land. Rice paddies provide the habitats for many organisms including endemic species, sustaining high biodiversity. Insect natural enemies inhabiting rice paddies have an important function for rice production as agents of ‘ecosystem services’ because they play a major role in suppressing rice pests. The diversity and abundance of natural enemies can be a good index reflecting the ‘healthiness’ of agro-ecosystem services in rice paddies. The present study investigates whether insect natural enemies could be good biological indicators for general arthropod biodiversity and agricultural practice. First, the concept of ideal bio-indicators was summarized. The strategy to explore and select such bio-indicators was then proposed. Lastly, field survey was made to evaluate the abundance and biodiversity of natural enemies in Japanese rice paddies where chemical inputs, i.e., insecticide use, were different. The results showed that reduction of chemical inputs led to an increase in species richness or diversity of natural enemies including parasitoids and predators. Then, the data were analyzed to examine suitable indicator species to assess environmental soundness of agricultural practice and biodiversity in rice paddies. The density of several species of natural enemies did respond both to pesticide use and to general arthropod biodiversity. The analyses thus have indicated that natural enemies can be suitable as bio-indicators. Usefulness of indicator species in rice paddies is discussed in the context of ecologically sound agriculture..
44. Takatoshi Ueno, Bioindicators of Biodiversity and Farming Practice in Rice Paddies, International Journal of Chemical, Environmental & Biological Sciences, 1, 84-87, 2013.01, Rice paddies occupy the largest cultivated area in agricultural land of Asia and create the habitats for many organisms, sustaining high biodiversity.

47. Takatoshi Ueno, Environmentally sound agro-practice, biodiversity and indicator species in rice paddies., EEBS, 2012.10, Rice paddies occupy the largest cultivated area in agricultural land and provide the habitats for many organisms. Thus, rice paddies are a key ecosystem in agricultural land that sustains a high level of agro-biodiversity. Natural enemies have an important function for crop production as agents of ‘ecosystem services’ because they play a major role in suppressing pests. The diversity and abundance of natural enemies can be a good index reflecting the ‘healthiness’ of agro-ecosystem services in rice paddies. In the present study, a survey was made to investigate the abundance and biodiversity of natural enemies in rice paddies where chemical inputs, i.e., insecticide use, were different. The reduction of chemical inputs led to an increase in species richness or diversity of natural enemies like parasitoids and spiders. Then, it was analyzed to explore suitable indicator species to assess environmental soundness of agricultural practice and biodiversity in rice paddies. Seven spotted ladybird beetle, Coccinella septempunctata, (Coleoptera: Coccinellidae) and a web-constructing araneid spider, Neoscona adianta, (Araneae: Araneidae) were among the commonest species of predators detected in paddy fields, and were tested to examine whether the density of the two could reflect the levels of chemical input and biodiversity. The density of the ladybird did not respond both to pesticide use and to biodiversity, indicating that this species was not suitable as an indicator. In contrast, the araneid spider increased both with a reduction of pesticide use and with an increase of biodiversity. Neoscona adianta was hence a good candidate of natural enemies to assess agricultural practice and biodiversity in rice paddies. Thus, it is possible to select species that are ideal bioindicators for monitoring both environmental soundness and biodiversity in agriculture. Usefulness of indicator species in rice paddies is discussed..
