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 کاملSpore Density and Viability of Entomopathogenic Fungal Isolates from Indonesia, and Their Virulence against Aphis gossypii Glover (Homoptera: Aphididae).
The focus of this study was on quantifying fitness attributes, such as spore density and viability, and determining the virulence level against aphid (Aphis gossypii) nymphs of isolates from the fungal species Beauveria bassiana and Metarhizium anisopliae. The fungal isolates were obtained from several insects, including Plutella xylostella, Hypothenemus hampei, Bronstispa longissima, A. gossyp...
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 کاملThiamethoxam Resistance in Aphis gossypii Glover Relies on Multiple UDP-Glucuronosyltransferases
Uridine diphosphate (UDP)-glycosyltransferases (UGTs) are major phase II enzymes that conjugate a variety of small lipophilic molecules with UDP sugars and alter them into more water-soluble metabolites. Therefore, glucosidation plays a major role in the inactivation and excretion of a great variety of both endogenous and exogenous compounds. In this study, two inhibitors of UGT enzymes, sulfin...
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 ...
