We examined the genetic variation in the sequences of cytochrome c oxidase subunit I gene (DNA barcode region) and some other regions of mitochondrial DNA of sweet potato weevil, Cylas formicarius (Fabricius, 1798) (Coleoptera: Brentidae), and West Indian sweet potato weevil, Euscepes postfasciatus (Fairmaire, 1849) (Coleoptera: Curculionidae), in Japan. In the DNA barcode region of C. formicarius...... hiện toàn bộ
Survival of Bactrocera latifrons (Diptera: Tephritidae) adults under constant and fluctuating low temperaturesApplied Entomology and Zoology - Tập 49 - Trang 411-419 - 2014
Shun-ichiro Takano
Bactrocera latifrons (Hendel) is believed to have originated in Southeast Asia but has invaded Hawaii and most recently East Africa. This insect has also been recorded on Okinawa Island, the far south of Kyushu Island, Japan. To assess the overwintering ability of B. latifrons adults, survival at constant temperatures (8, 10, 12, 14, 15 °C) and under fluctuating thermal regimes (F...... hiện toàn bộ
Geographical variation in diapause development in eggs of Sympetrum frequens (Odonata: Libellulidae)Applied Entomology and Zoology - Tập 50 - Trang 263-270 - 2015
Keiji Nakamura, Kazuki Takashima
Geographical differences causing variations in the egg period and the effects of environmental factors on diapause development were examined in Sympetum frequens (Selys), a univoltine species with an obligatory egg diapause for overwintering. Eggs were obtained from females collected from 11 localities in Japan and incubated under six different combinations of photoperiod and temperature. No clear...... hiện toàn bộ
