Two experiments were done to determine the susceptibility of six wild potato accessions to the aphids Macrosiphum euphorbiae (Thomas) (Hemiptera: Aphididae) and Myzus persicae (Sulzer). Densities of aphid colonies were compared between caged Solanum pinnatisectum Dunal (Solanales: Solanaceae), S. polyadenium Greenmam, S. tarijense Hawkes, S. infundibuliforme Philippi, S. oplocense Hawkes, and S...

Thrips is one of the most harmful insect groups attacking many field and vegetable crops. Predatory mites, especially those in family Phytoseiidae, are considered as good bioagents to control thrips where application of chemical pesticides can be decreased. This work was conducted to evaluate the efficacy of the two phytoseiid mites, Amblyseius swirskii (Athias-Henriot) and Neoseiulus cucumeris...

Abstract Background Selection of suitable predators for the control spider mite, Panonychus citri is always a challenge due to lack their reliable predicted efficacy. In this laboratory study, biological potential Neoseiulus californicus , N. cucumeris and Scapulaseius newsami, against P. using “Relative Control Potential” (RCP) metric compare efficacies was evaluated. The functional response t...

Predatory phytoseiid mites as biocontrol agents are increasingly used in pest control programs across the globe, and Neoseiulus cucumeris (Oudemans) is one of them, which a commercially available agent against various pests greenhouse crops. This generalist predatory mite can feed on different foods diets, including small arthropods pollen. Feeding reproducing pollen diet considerable character...

Amblyseius swirskiiAthias-Henriot (Acari: Phytoseiidae) is a predatory mite used to control thrips (Thysanoptera), whiteflies (Bemisia tabaci Genn., Hemiptera: Aleyrodidae), and broad mites (BMs) (Polyphagotarsonemus latus Banks, Acari: Tarsonemidae). Dispersal of A. swirskii, using the ornamental pepper "Explosive Ember" as a banker plant was evaluated for control of BMs in high-tunnel peppers...

Sheath blight of rice (Oryza sativa L.) is a major rice disease throughout the world including the southern United States. This disease, which is caused by Rhizoctonia solani Kühn (teleomorph: Thanatephorus cucumeris (Frank) Donk), was first reported in 1910 and now occurs throughout temperate and tropical production areas, being most prominent where rice is grown under intense, high-fertility ...
