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...
متن کاملBottom-up Effect of Two Host Plants on Life Table Parameters of Aphis gossypii (Hemiptera: Aphididae)
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...
متن کاملMorphological discrimination of Aphis gossypii (Hemiptera: Aphididae) populations feeding on Compositae.
Aphis gossypii Glover is a polyphagous aphid pest with a worldwide distribution. However, there is evidence that on a global scale the name A. gossypii is being applied to a number of forms with different life cycles and/or host-plant associations. Morphometric variation of A. gossypii samples from crops and non-cultivated plants in many parts of the world was examined, to determine whether thi...

شته جالیز Hemiptera: Aphididae)) Glover Aphis gossypii یکی از آفات مهم و خسارت‌زا در مزارع و گلخانه‌ها بوده و استفاده از آفتکشها یکی از روشهای کنترل این آفت محسوب میشود. کاربرد بی‌رویهی آفتکشها علاوه بر ایجاد مقاومت در آفات، منجر به بجا گذاشتن باقیمانده آن روی گیاهان میشود. اتخاذ تدابیری از جمله کاهش دز مصرف میتواند در سلامت مصرف کنندگان موثر باشد. در پژوهش حاضر، حساسیت مراحل مختلف پورگی ...
