چکیده
The biological effects of entomopathogenic species, Beauveria bassiana (Bals.-Criv.) Vuill and Akanthomyces attenuatus Zare & Gams on cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae) nymphs at 1x108 conidia concentration (ml-1) were investigated the laboratory conditions. experiments conducted 25°C, 65% relative humidity, 16:8 hours lighting in a climatic cabinets. Alive recorded 1st, 3rd, 5th, 7th, 9th days incubation. B. caused higher mortality than A. did. A statistical difference was determined between isolates 7th experiment. highest rates isolate with 72% 54% day. LT50 value for B.bassiana 6.02 8.33 days, respectively.

Identification of Aphis gossypii Glover (Hemiptera: Aphididae) Biotypes from Different Host Plants in North China.
BACKGROUND The cotton-melon aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a polyphagous species with a worldwide distribution and a variety of biotypes. North China is a traditional agricultural area with abundant winter and summer hosts of A. gossypii. While the life cycles of A. gossypii on different plants have been well studied, those of the biotypes of North China are still uncle...
متن کاملMultivariate approach to quantitative analysis of Aphis gossypii Glover (Hemiptera: Aphididae) and their natural enemy populations at different cotton spacings
The relationship between pests and natural enemies using multivariate analysis on cotton in different spacing has not been documented yet. Using multivariate approaches is possible to optimize strategies to control Aphis gossypii at different crop spacings because the possibility of a better use of the aphid sampling strategies as well as the conservation and release of its natural enemies. The...

Aphis gossypii Glover is one of the most important pests of greenhouse cucumber and pepper in the world and Iran. In this research, life table and biology of A. gossypii were investigated on cucumber (Cucumis sativus cv. Super Sultan) and pepper (Capsicum annum cv. Marqueza) in a growth chamber at 25±1°C and 60±5% RH and a photoperiod of 14 L: 10 D hour. The results showed that developmental ti...
