Dr. Soma Karmakar

The phytophagous mites attack the fruit plants and cause substantial economic loss by sucking the plant sap and cause chemical,

physiological and mechanical injuries which ultimately lead to reducing yield and economic loss. The use of synthetic chemical

pesticides to control the mite problem is long in use in agricultural practices. But these type of pesticides have very hazardous

effect on environment. The predatory mites can be an alternative to synthetic chemical pesticides and useful in IPM. In the present

study the correlation coefficient has been worked out between the Phytophagous and Predatory mite population occurring on

Guava (Psidium guajavae) for three consecutive years which are 2009–2010, 2010– 2011 and 2011 –2012 and the correlation

coefficient were –0.668, –0.404 and –0.342 respectively. And hence the the predatory mites have been suggested as an alternative

to synthetic chemical pesticides.
