Seasonal incidence of scale insects, whiteflies and psyllids (Hemiptera) of olive and their natural enemies in Egypt [PDF]

open access: yesEgyptian Academic Journal of Biological Sciences. A, Entomology, 2011
Scale insects, whiteflies and psyllids (Hemiptera) are the main olive pests in Egypt. The aim of this work is to study the incidence of scale insects, whiteflies and psyllids and their natural enemies on olive trees in different locations in Egypt during 2009-2010. The results of the present work indicated that the seasonal abundance of Lucaspis riccae

A complex landscape favours the abundance and species richness of syrphids (Diptera: Syrphidae) in olive groves

open access: yesEcological Entomology, Volume 48, Issue 5, Page 568-581, October 2023., 2023
Landscapes dominated by olive groves do not encourage syrphid population. Syrphids can help pest control in olive groves. A complex landscape structure can contribute to the ecosystem service biological pest control. Abstract Sustainability of agroecosystems depends on the ecosystem services, provided by beneficial organisms, such as the syrphids ...

The South American fruit fly : an important pest insect with RNAi-sensitive larval stages [PDF]

open access: yes, 2019
RNA interference (RNAi) technology has been used in the development of approaches for pest control. The presence of some essential genes, the so-called "core genes," in the RNAi machinery is crucial for its efficiency and robust response in gene ...
