Predation 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 کاملSusceptibility of a native and an exotic lady beetle (Coleoptera: Coccinellidae) to Beauveria bassiana.
The exotic multicolored Asian lady beetle, Harmonia axyridis, became established and recently spread across much of North America and southern Canada. In a habitat now used by both the invading H. axyridis and a native lady beetle, Olla v-nigrum, we discovered that the native lady beetle was commonly infected by Beauveria bassiana; whereas, the exotic H. axyridis, was not. Laboratory assays rev...
متن کاملbionomics of aphis gossypii (homoptera: aphididae) and its predators coccinella septempunctata and hippodamia variegata (coleoptera: coccinellidae) in natural conditions
bionomics of aphis gossypii glover and its predators coccinella septempunctata l. and hippodamia variegata goeze were studied in varamin (tehran province) during 11th may to 5th october 2006 on eggplant crop, with the interaction (density dependence) between the aphid and either of the predators determined. the reliable sample size (number of leaves) with a maximum variation of 6.73% was about ...
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 کاملAphid Species Affect Foraging Behavior of Coccinella septempunctata (Coccinellidae: Coleoptera).
BACKGROUND Flowers are admirable in scenic good looks and artistic beautification. These are also playing necessary roles in therapeutic preparations. Aphid is an important sucking pest of various flowers in ornamental territories and it is generally controlled by predators, so it was necessary to evaluate which aphid species affect the predator more or less. MATERIALS AND METHODS Biocontrol ...
