Abstrakt: This study incudes a field experiment conducted in the farmer's holding during 2016-2017 to develop IPM module against the sucking pests of guava. The results revealed that the aphid Aphis gossypii could be controlled with IPM module, reducing the incidence to 6.18 aphids/ 3 leaves/ as against a maximum of 157.85 aphids/ 3 leaves/ tree). Planococcus citri incidence could be reduced up to 6.80 mealy bugs/ 3 leaves/ tree from 233.11 mealy bugs in untreated control; likewise Paracoccus marginatus got reduced to 1.99 mealy bugs/ 3 leaves/ tree as against 225.45; Ferrisia virgata incidence got reduced to 13.49/ 3 leaves/ tree) followed by farmer practice (19.80) as against 205 in untreated control. In case of whitefly Aleurodicus dispersus, IPM module reduced the incidence rate to 12.26 whiteflies/ 3 leaves/ tree, and it was followed by farmer practice, as against 193.49 in untreated control. A maximum yield of 7.68 kg/ tree was obtained with the IPM module as against 6.40 kg/ tree with farmers' practice. [ABSTRACT FROM AUTHOR]
