tailieunhanh - Biological control of Phytophagous mites: A review

Phytophagus mites are gaining importance at present since their incidence is high. Farmers rely only on acaricides and other chemical pesticides for the management of these mites results in destruction of natural enemies, pesticide resistance and pesticide residues in crops, environment pollution etc. Hence, there is a need to find alternate to manage the phytophagous mites. Exploitation of natural enemies viz., predaceous insects, predatory mites and acaropathogenic fungi are the tools in pest management programmes. Among the predatory mites, the family Phytoseiidae is known to have potential predators which have proved their efficacy against several mite pests in different crops. Classical, augmentative and conservation biocontrol programmes using some of the important biocontrol agents remained as success stories in developed countries. However, the potential use of s biocontrol agents of mite pests is yet to be exploited in developing countries like India. In this context, the present review is about updated information on predaceous insects, predatory mites and acaropathogens against phtophagous mites. | 2019 8 1 2153-2160 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 01 2019 Journal homepage http Review Article https Biological Control of Phytophagous Mites A Review E.

Introduction Phytophagous mites attack most of the agricultural and horticultural crops. These pests are distributed worldwide causing loss of quality and yield or death of host plants by sucking out the cell-contents of leaf. Yield loss due to .
