The association of the development of the internal reproductive organs of male desert locusts, Schistocerca gregaria (Orthoptera: Acrididae), with age, phase and the effect of exposure to pheromones
Autor: Satoshi HIROYOSHI, Takayuki MITSUNAGA, Gadi V.P. REDDY
Publikováno v: European Journal of Entomology, Vol 119, Iss 1, Pp 300-308 (2022)
The regulation of the development of the male reproductive organs in insects is still an open question. Although the desert locust, Schistocerca gregaria, has been extensively examined, there is little information on the effects of phase and pheromon

Effects of the juvenile hormone mimic NC-184 on the development of the reproductive organs and mating behaviour of nymphs of the desert locust, Schistocerca gregaria (Orthoptera: Acrididae)
Autor: Satoshi HIROYOSHI, Elizabeth KOKWARO, Sai METTUPALLI, Takayuki MITSUNAGA, Shigemi YAGI, Gadi V.P. REDDY
Publikováno v: European Journal of Entomology, Vol 116, Iss 1, Pp 477-485 (2019)
The insect growth regulator NC-184, a juvenile hormone mimic, prevents moulting to the adult stage in the desert locust, Schistocerca gregaria (Forskål) (Orthoptera: Acrididae). Male nymphs treated in the penultimate or final nymphal instar with NC-

Quantitative response to photoperiod and weak coupling between seasonal morphs and diapause regulation in the Asian comma butterfly, Polygonia c-aureum (Lepidoptera: Nymphalidae)

Publikováno v: European Journal of Entomology, Vol 116, Iss 1, Pp 123-132 (2019)
Reproduction and wing patterns (shape and colouration) in Polygonia c-aureum L. (Lepidoptera: Nymphalidae) are regulated by both photoperiod and temperature experienced during the immature stages, which result in the development of summer or autumn f

Effects of Age, Phase Variation and Pheromones on Male Sperm Storage in the Desert Locust, Schistocerca gregaria
Autor: Satoshi Hiroyoshi, Takayuki Mitsunaga, Tomoko Ganaha-Kikumura, Gadi V. P. Reddy
Publikováno v: Insects, Vol 12, Iss 7, p 642 (2021)
In general, sperm produced in the testis are moved into the seminal vesicle via the vas deferens in insects, where they are stored. How this sperm movement is controlled is less well understood in locusts or grasshoppers. In this study, the effects o

Field and Laboratory Studies on the Ecology, Reproduction, and Adult Diapause of the Asian Comma Butterfly, Polygonia c-aureum L. (Lepidoptera: Nymphalidae)
Autor: Satoshi Hiroyoshi, Gadi V. P. Reddy
Publikováno v: Insects, Vol 9, Iss 4, p 169 (2018)
Adult diapause and reproduction of a nymphalid butterfly, Polygonia c-aureum L., were investigated in field and laboratory examinations. Laboratory studies showed that old virgin male butterflies of non-diapausing generations had heavy accessory glan

Effects of photoperiod and aging on the adult spermatogenesis of Polygonia c-aureum (Lepidoptera: Nymphalidae), in relation to adult diapause

Adult spermatogenesis of Polygonia c-aureum was compared between non-diapausing and diapausing butterflies before overwintering. This butterfly has seasonal polyphenism, i.e., summer and autumnal forms. Summer form butterflies that emerged in summer

Positional Relationships among Male Reproductive Organs in Insects
Autor: Gadi V. P. Reddy, Satoshi Hiroyoshi
Publikováno v: Male Reproductive Anatomy ISBN: 9781839685248
The location, morphology and function of male internal reproductive organs in insects have been extensively studied, but the relative positioning of those organs is less understood. Position and morphology of the testis, vas deferens, seminal vesicle
