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...

Aphis gossypii Glover and Acyrthosiphon Mordvilko (Hemiptera: Aphididae) are key pests of cotton, Gossypium hirsutum L., known to induce cotton host plant defense responses. Deep RNA sequencing the transcriptome followed by differential expression analyses were performed clarify molecular mechanisms in response feeding these aphid pests. We found 6,565 genes differentially expressed Ac. 823 tha...

Ann. Entomol. Soc. Am. 81(6): 950-953 (1988) ABSTRACT A simple root-warming device maintains the plants' roots at a higher temperature than that at which the rest of the plant is held. This permits the host plant to retain turgor, not wilt, and therefore remain suitable for and attractive to phytophagous insects. The technique was demonstrated in a development and fecundity test using the cotto...

The objective of this study was to evaluate the functional response of Orius insidiosus preying on the third and fourth instars of Aphis gossypii nymphs that were reared on transgenic NuOPAL (Bollgard I Event 531) and conventional Buriti cotton varieties. Fifty O. insidiosus female bugs aged 12–24h were distributed into five different Petri dishes with different densities of A. gossypii (2, 4, ...
