The life history and feeding habits of Lasioseius scapulatus, an ascid predator and potential biocontrol agent of nematodes, was examined. Reproduction was asexual, and the life cycle was 8-10 days at room temperature. Life history consisted of the egg, protonymph, deutonymph, and adult. Both nymphal stages and the adult captured and consumed nematodes. Two fungal genera and eight genera of nem...

Tetranychus macfarlanei is a potential threat to various economically important crops. Chemical control widely used this spider mite, but the exclusive reliance on chemical acaricides now being questioned, and entomopathogens are emerging as promising alternative. The efficacy of largely depends abiotic factors like temperature, humidity, rainfall etc. experiments were conducted determine effec...

Control of the poultry red mite Dermanyssus gallinae is a challenge for organic as well as conventional egg producers. In organic agriculture, control should be attempted by mechanically acting substances (e.g. oils or diatomaceous earth), before acaricides are applied. Diatomaceous earth (DE) without acaricides was at least as effective as DE supplemented with pyrethrum or essential oils and a...

Oils are some of the most efficient and secure alternatives to synthetic fungicides, acaricides insecticides used as pesticides for decades. Around world, mineral oils a potential pesticide against many pests. To provide novel active ingredients new formulations industry, major goal this research was formulate one petroleum fractions test its acaricidal efficiency two-spotted spider mite (TSSM)...

Climate change will bring more drought periods that will have an impact on the irrigation practices of some crops like tomato, from standard water regime to deficit irrigation. This will promote changes in plant metabolism and alter their interactions with biotic stressors. We have tested if mild or moderate drought-stressed tomato plants (simulating deficit irrigation) have an effect on the bi...

The predatory mite Amblyseius swirskii (Athias-Henriot) (Acari: Phytoseiidae) is currently used as an efficient biological control agent of thrips, whiteflies and spider mites, which are economically damaging pests ornamental plants vegetable crops grown in greenhouses fields worldwide. Currently, the effects relative humidity (RH) water availability on optimal growth A. unknown. Here, we test ...
