Time Delay and Initial Population Density Affect Interactions Between <I>Encarsia pergandiella</I> Howard and <I>Eretmocerus mundus</I> Mercet (Hymenoptera: Aphelinidae)

Biology of Bemisia tuberculata Bondar (Aleyrodidae) and parasitism by Encarsia porteri (Mercet, 1928) (Hymenoptera, Aphelinidae) on cassava plants.

The whitefly Bemisia tuberculata has caused serious damage to cassava producing areas in the state of Mato Grosso do Sul. However, little is known about the biological characteristics of this species. The objective of this study was therefore, to monitor the development of this species bred on cassava plants under controlled greenhouse conditions, and to determine its most vulnerable stages and...

عملکرد تولید¬مثلی زنبور prospaltella berlesei به عنوان یکی از مهم¬ترین دشمنان طبیعی سپردار توت در شرایط کنترل شده آزمایشگاهی (دماهای 1± 25 و 1± 28 سانتی¬گراد، رطوبت نسبی 10± 70 و دوره نوری 8 : 16 ساعت (تاریکی: روشنایی)) روی سیب¬زمینی مورد بررسی قرار گرفت. تراکم¬های 5، 10، 20، 40، 60، 80 و100 هریک از سنین اول تا سوم سپردار توت در 10 تکرار به مدت 24 ساعت در اختیار زنبور بالغ دو روزه قرار گرفت. در...

Does Certain Host and Food Deprivation Period Affect Host Feeding and Oviposition Behaviour of Eretmocerus warrae (Hymenoptera: Aphelinidae)

Eretmocerus warrae (Naumann and Schimdt) is a thelytokous aphelinid parasitoid of the greenhouse whitefly, Trialeurodes vaporariorum (Westwood). It was first detected in New Zealand in 1997 during a survey of greenhouses in Auckland. We investigated the effects of certain duration of food and host deprivation after emergence on feeding, oviposition behavior and egg resorption of E. warrae with ...
