long-term cold response in overwintering adults of ladybird hippodamia variegata (coleoptera: coccinellidae)
hippodamia variegata is an efficient and most abundant predatory coccinellids in many countries. understanding the ability of long-term low temperature survival in beneficial insects can be used to make better predictions about subsequent abundance and hence the biological control potential in the next spring and summer. so in this study, effects of long-term temperatures were investigated on m...
متن کاملPredation rate of Hippodamia variegata (Coleoptera: Coccinellidae) feeding on different densities of Aphis gossypii (Hemiptera: Aphididae)
نرخ شکارگری اساس هر پژوهش در برهم‌کنش شکار-شکارگر است و یکی از اجزای مهم در انتخاب شکارگران در کنترل بیولوژیک بهشمار میرود. نرخ شکارگری کفشدوزکHippodamia variegata (Goeze) با تغذیه از تراکمهای مختلف (20، 40، 60، 80 و 100) عدد از پورههای سن سوم شته پنبه Aphis gossypii Glover در شرایط آزمایشگاهی (1±25 درجه سلسیوس، رطوبت نسبی 5 ±65 درصد و دوره نوری 16 ساعت روشنایی و 8 ساعت تاریکی) بررسی شد. ...
متن کاملDeterminants of acute mortality of Hippodamia convergens (Coleoptera: Coccinellidae) to ultra-low volume permethrin used for mosquito management
There are relatively few experimental studies and risk assessments of the effects on non-target insects from ultra-low volume (ULV) insecticides used for management of adult mosquitoes. Therefore, we evaluated factors that may influence the ability of an insect to intercept the insecticide at the time of application by using Hippodamia convergens (Coleoptera: Coccinellidae) in field bioassay ex...
متن کاملFunctional response of larval and adult stages of Hippodamia variegata (Coleoptera: Coccinellidae) to different densities of Aphis fabae (Hemiptera: Aphididae).
We compare the efficiencies of different stages of Hippodamia variegata (Coleoptera: Coccinellidae) preying on Aphis fabae (Scolpoli) (Hemiptera: Aphididae) by estimating the functional responses of all stages. The experiments were carried out on leaf disks in petri dishes with 15-20 replicates. Our results revealed that all larval instars and adult males and females of H. variegata exhibited t...
متن کاملPyrethroid resistance and its inheritance in a field population of Hippodamia convergens (Guérin-Méneville) (Coleoptera: Coccinellidae)
The convergent lady beetle (CLB), Hippodamia convergens (Guérin-Méneville), a species widely distributed and used in biological control, has exhibited high survival under field and laboratory conditions when treated with field rates of the pyrethroid k-cyhalothrin, a highly unusual phenomenon for a natural enemy. This work investigated and characterized the phenomenon of pyrethroid resistance i...
