Effect of Selecting Cereal Leaf Beetle (Coleoptera: Chrysomelidae) Males by Age and Feeding Behavior on Nondiapause Progeny [PDF]

open access: yes, 2017
In a nondiapause culture of cereal leaf beetles, Oulema melanopus (Coleoptera: Chrysomelidae), females ovipositing within 20 days after emergence were considered nondiapause.

Photoperiodic control of the intensity of diapause and diapause development in the bean bug, Riptortus clavatus (Heteroptera: Alydidae)

open access: yesEuropean Journal of Entomology, 2000
Adult diapause in Riptortus clavatus (Thunberg) was induced by short-day photoperiods, and the critical daylength for its induction was 13.5 h. When insects were reared from eggs under diapause-inducing photoperiods near the critical daylength, the ...

Physiological and biochemical differences in diapause and non-diapause pupae of Sericinus montelus (Lepidoptera: Papilionidae)

open access: yesFrontiers in Physiology, 2022
The swallowtail butterfly, Sericinus montelus Gray, is endemic to East Asia, has high ornamental value but faces an increased risk of extinction. To understand the overwintering strategies of this species, the dynamic changes in supercooling point (SCP ...

Summer Diapause of the Clover Leaf Weevil, \u3ci\u3eHypera Punctata,\u3c/i\u3e and Lesser Clover Leaf Weevil, \u3ci\u3eHypera Nigrirostris,\u3c/i\u3e in Wisconsin [PDF]

open access: yes, 2017
Low respiration rates, immobility, lack of feeding, and undeveloped reproductive systems confirmed a summer diapause in the overwintered and current-year adults of the clover leaf weevil, Hypera punctata, and lesser clover leaf weevil, Hypera ...

Differences in the Development of Internal Reproductive Organs, Feeding Amount and Nutrient Storage between Pre-Diapause and Pre-Reproductive Harmonia axyridis Adults

open access: yesInsects, 2019
Diapause control is one of the successful methods for long-term cold storage of biological control organisms without decreasing their fitness. Sufficient preparation before diapause is essential for successful diapause initiation and maintenance ...

Life History of \u3ci\u3eMesovelia Mulsanti\u3c/i\u3e (Hemiptera: Mesoveliidae) in Southern Illinois [PDF]

open access: yes, 2017
The life history of Mesovelia mulsanti was studied during 1983-1986. This species was apparently trivoltine with a partial 4th generation at the end of the year. It overwintered as eggs. First ins tars appeared in mid-April followed by marked overlapping

Physiological mitochondrial ROS regulate diapause by enhancing HSP60/Lon complex stability in Helicoverpa armigera

open access: yesJournal of Integrative Agriculture, 2022
Diapause is a long-lived stage which has evolved into an important strategy for insects to circumvent extreme environments. In the pupal stage, Helicoverpa armigera can enter diapause, a state characterized by significantly decreased metabolic activity ...
