Bio-intensive management of pink mealybug, Maconellicoccus hirsutus green in mulberry.

摘要

A study was conducted to evaluate organics viz., botanicals, fish oil products and predators for the management of Pink mealybug, Maconellicoccus hirsutus in mulberry. Among the treatments tested, fish oil rosin soap (FORS) @ 25 g/lit was found to be very effective causing highest per cent mortality of M. hirsutus of 86.52 and 86.84 per cent on 15 DAT in first and second trials respectively. This was followed by 78.57 and 86.22 per cent in fish oil rosin liquid @ 0.2 per cent on 15 DAT during first and second trials respectively. In another trial, highest per cent reduction of pink mealybug was recorded in two trials on 60 days after release of adult Cryptolaemus montrouzieri beetles at 5 nos. (67.7 and 50.2) and 10 nos. (79.4 and 66.2) per square meter.
