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 کاملSurvey of Aphis Gossypii on Crop Plants
Tests were conducted to determine if age of mass reared adult female Mediterranean fruit flies, Ceratitis capitata (Wiedemann), affected the viability of their offspring. Samples of eggs (0.4 g each) were collected on five consecutive days (4 to 8 d past adult emergence) from individual 660-liter adult colony screen cages and were reared in separate trays containing 0.5 liter of artificial diet...
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 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 ...
متن کاملAn 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...
