Gene Expression Profiling in Winged and Wingless Cotton Aphids, Aphis gossypii (Hemiptera: Aphididae)
While trade-offs between flight capability and reproduction is a common phenomenon in wing dimorphic insects, the molecular basis is largely unknown. In this study, we examined the transcriptomic differences between winged and wingless morphs of cotton aphids, Aphis gossypii, using a tag-based digital gene expression (DGE) approach. Ultra high-throughput Illumina sequencing generated 5.30 and 5...
متن کاملIntegrated Field Management of Aphids (myzus Persicae Sulz. and Aphis Gossypii Glov. Together) on Potato (solanum Tuberosum L.) Using Bio-pesticides
Potato (Solanum tuberosum L.) is cultivated in India in a commercial scale and this crop is susceptible to various insect pests of which aphids (both Myzus persicae Sulzer and Aphis gossypii Glover) cause heavy damage especially by spreading virus diseases. Studies were made to evaluate efficacy of extracts from plants such as Pongamia pinnata L. and Nicotiana tabacum L. and Polygonum hydropipe...
متن کاملNatural Attachment Sites for Capilliconidia of Neozygites fresenii (Entomophthorales: Neozygitaceae) on Cotton Aphids Aphis gossypii (Homoptera: Aphididae)
The cotton aphid fungus, Neozygites fresenii (Entomophthorales: Neozygitaceae) is an important pathogen of the cotton aphid Aphis gossypii (Glover) (Homoptera: Aphididae). The capilliconidia of this pathogenic fungus adhere to the integument of aphids, beginning the cycle of mycosis. Few studies have been conducted that attempt to quantify or examine the points of infection of an entomopathogen...
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 کاملمقایسهی پارامترهای رشد جمعیت کفشدوزک Coccinella septempunctata (Col.: Coccinellidae) و شته‌ی جالیز، Aphis gossypii (Hem.: Aphididae)، در شرایط آزمایشگاهی
حشرات کامل کفشدوزک هفت‌نقطه‌ای، Coccinella septempunctata L.، و شته‌ی جالیز، Aphis gossypii Glover، از مزارع خیار اطراف رشت جمع‌آوری شدند و در اتاقک رشد در دمای C2 26 و دوره‌ی نوری 8 :16 ساعت (تاریکی: روشنایی) و رطوبت نسبی 5 65% پرورش داده شدند. ده جفت کفشدوزک در حال جفت‌گیری که 48 ساعت از ظهورشان گذشته بود، به‌طور جداگانه به ظروف پلاستیکی شفاف به ابعاد 12 × 10 × 8 سانتی‌متر که درپوش آن‌ها...
