Sweet pepper is now grown, in tropical and subtropical areas, under the integrated pest management (IPM) tactic of 'physical barrier', whereas it was once grown primarily in open fields. This… (More)
Phytoplasmas are phloem-limited, insect-transmitted, plant pathogenic bacteria that are responsible for hundreds of diseases world-wide. Because transmission occurs quickly, plants become infected… (More)
Samples of a dipteran pest of wheat were tested to confirm identity, describe local populations and suggest the use of deploying resistance (R) genes in wheat cultivars for control of Mayetiola… (More)
Bacteria in the genus Rickettsiella (Coxiellaceae), which are mainly known as arthropod pathogens, are emerging as excellent models to study transitions between mutualism and pathogenicity. The… (More)
This review discusses the economically important pest mites (Acari) of greenhouses, aspects of their biology, and the acarine predators that attack them as well as various insect pests. Greenhouse… (More)
Aqueous extracts from two plants, Urginea maritima L. (Liliaceae) and Euphorbia myrsinites L. (Euphorbiaceae), were tested for their insecticidal activity against the leafminer Liriomyza trifolii… (More)
