An example of host plant expansion of host-specialized Aphis gossypii Glover in the field
The host plant expansion of host-specialized Aphis gossypii (Glover) has been well studied in the laboratory; however, this phenomenon is poorly understood in the field. Here, we provide a series of laboratory and field experiments to assess the role of zucchini in the host plant expansion of cotton-specialized aphids. We observed that cotton-specialized aphids possessed the ability to expand o...
متن کاملINSECTICIDE RESISTANCE IN THE COTTON APHID, Aphis gossypii GLOVER IN EGYPT
The cotton aphid, Aphis gossypii Glover (Hemiptera Aphididae), is one of the most important sap sucking pests in many cotton-growing areas world-wide. In this study, the efficacies of seven insecticides [organophosphate (Fenitrothion & Pirimiphos-methyl), carbamate (Carbosulfan & Aldicarb), pyrethroid (Lambda-Cyhalothrin & Deltamethrin) and imidaclopride (Confidor)] were determined against four...
متن کاملAphis gossypii
BIOLOGY/ECOLOGY Dispersal mechanisms Flight range of winged adults is very limited. Long-range dispersal of eggs, immature stages and adults is manmediated with the transport of infested plant material. Reproduction The taxonomic status of this alien aphid is problematic, and hence the interpretation of biological information is difficult. Moreover, different biotypes exhibiting host preference...
متن کاملHypersensitive response to Aphis gossypii Glover in melon genotypes carrying the Vat gene.
Aphis gossypii Glover causes direct and indirect damage to Cucumis melo L. crops. To decrease the harmful effects of this pest, one of the most economically and environmentally acceptable options is to use genetically resistant melon varieties. To date, several sources of resistance carrying the Vat gene are used in melon breeding programmes that aim to prevent A. gossypii colonization and the ...
متن کاملبرآورد پارامترهای جدول زندگی باروری شته جالیز (Aphis gossypii Glover)
پارامترهای جدول زندگی باروری شته جالیز بر روی سه گیاه خیار، کدوتنبل و کدو مسمایی در شرایط آزمایشگاه با دمای 1±25 درجه سانتیگراد، رطوبت نسبی 5±75 درصد و دوره نوری 8 : 16 (تاریکی: روشنایی) بررسی گردید. به منظور محاسبه خطای استاندارد پارامترهای رشد جمعیت از روش جکنایف استفاده شد. نرخ خالص تولید مثل روی خیار، کدوتنبل و کدو مسمایی به ترتیب برابر با 806/7±789/76، 409/6±704/32 و 041/4±995/43 محاسبه ...
