Field experiment was conducted at the farm of Faculty Agriculture, GomalUniversity, Dera Ismail Khan to determine integrated effect nitrogenous fertilizer and syntheticinsecticides on aphid, Lipaphis erysimi (Kaltenbach) (Homoptera: Aphididae) population in canolacrop during 2010-11. Results showed that tested insecticides significantly reduced aphid populationcompared control. Minimum (8.67aph...

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...

Bu çalışmanın amacı 2020-2021 yılları bahar ve yaz aylarında Çanakkale ili meyve bahçelerindeki yumuşak sert çekirdekli ağaçları yabancı otlarda beslenen yaprakbitleri (Hemiptera: Aphididae) üzerindeki predator syrphid türlerinin (Diptera: Syrphidae) belirlenmesidir. Toplamda 6 cinse bağlı türü 15 yaprakbiti tespit edilmiştir. En yaygın türleri 9 üzerinde belirlenen Episyrphus balteatus de Geer...

Aphids (Hemiptera: Aphididae) have been the focus of several studies with respect to their interactions with inherited symbionts, but bacterial communities of most aphid species are still poorly characterized. In this research, we used bar-coded pyrosequencing to characterize bacterial communities in aphids. Specifically, we examined the diversity of bacteria in two obligately parthenogenetic a...

This paper uses a methodology based in fuzzy sets theory in order to describe the interaction between the prey, Aphis glycines (Hemiptera: Aphididae) the soybean aphid, and its predator, Orius insidiosus (Hemiptera: Anthocoridae). Economic thresholds were already developed for this pest. The aim of this investigation was to develop a simple and specific methodology by fuzzy rule-based system to...

1. Pea aphids (Acyrthosiphon pisum Harris; Hemiptera: Aphididae) exhibit transgenerational wing polyphenism, in which unwinged females produce genetically identical winged offspring in response to environmental cues such as overcrowding and predation risk that indicate poor habitat quality. 2. Laboratory experiments were carried out to explore the intensity of the wing polyphenic response of pe...
