(1) Intraguild predation (IGP) can occur among aphidophagous predators thus reducing their effectiveness in controlling crop pests. Among ladybirds, Coccinella septempunctata L. and Hippodamia variegata Goeze are the most effective predators upon Aphis gossypii Glov., which is an economically important pest of melon. Understanding their likelihood to engage in reciprocal predation is a key poin...

Bu çalışma 2019-2020 yıllarında Tire ve Ödemiş (İzmir) ilçelerinde birinci ikinci ürün patates ile domates alanlarında Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)’ nın doğal düşmanlarının saptanması amacıyla yürütülmüştür. Örneklemeler haftalık olarak gerçekleştirilmiştir. Doğal düşmanlar atrap kültüre alma yöntemiyle elde edilmiştir. Birçok predatör parazitoit düşman türü saptanmıştır. ...

this paper is an attempt to fill all of previous literature of coccinellidae records and species distribution in different provinces of iran. distribution was extracted for each species from literatures. there are 6 subfamilies, 16 tribes, 32 genus and 117 species in iran. the largest subfamily, tribe and genus in iran were scymninae, scymnini and scymnus, respectively. the most distribution wa...

This study was performed on an alfalfa crop located on the central plain of La Araucanía Region, Chile and in the Laboratorio de Entomología Aplicada de la Facultad de Ciencias Agropecuarias y Forestales at the Universidad de La Frontera. Certain aspects of the biology of Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) were determined, more specifically in relation to its life cycle, s...

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...
