Aphis 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 کاملInterspecific Associations between Cycloneda sanguinea and Two Aphid Species (Aphis gossypii and Hyadaphis foeniculi) in Sole-Crop and Fennel-Cotton Intercropping Systems
Aphids cause significant damage to crop plants. Studies regarding predator-prey relationships in fennel (Foeniculum vulgare Mill.) and cotton (Gossypium hirsutum L.) crops are important for understanding essential ecological interactions in the context of intercropping and for establishing pest management programs for aphids. This study evaluated the association among Hyadaphis foeniculi (Passe...
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 کاملMolecular Characterization of the Aphis gossypii Olfactory Receptor Gene Families
The cotton aphid, Aphis gossypii Glover, is a polyphagous pest that inflicts great damage to cotton yields worldwide. Antennal olfaction, which is extremely important for insect survival, mediates key behaviors such as host preference, mate choice, and oviposition site selection. In insects, odor detection is mediated by odorant receptors (ORs) and ionotropic receptors (IRs), which ensure the s...
متن کاملInfluences of fertilization on Aphis gossypii and insecticide usage
Fertilization levels for ornamental crops may influence pest population dynamics, crop quality, and pest management strategy. We examined the effect of fertilization on population growth and within-plant distribution of melon or cotton aphid, Aphis gossypiiGlover, on potted chrysanthemum, Dendranthema grandiflora (Tzvelev). In terms of pest management implications, we also investigated the effe...
