monitored from 1st July to 30th September 2015 at Government Seed
Farm at Usta Muhammad, Balochistan using RCB design in three
replicates. Whitefly (Bemisia tabaci), Squash bug (Anasa tristis), Squash beetle, Epilachna borealis, Squash vine borer, Melittia
cucurbitae and Fruit fly Bactrocera cucurbitae were found infesting
Indian squash foliage and fruits. The nymphs/larvae and adult
populations were separately recorded. The data indicated that the
weekly population of Bemisia tabaci, Anasa tristis, Epilachna borealis,
Melittia cucurbitae and Bactrocera cucurbitae was significantly
fluctuated (P<0.05). The adult white fly population was in the range of
1.15-4.65/leaf averaging 2.57/leaf; while the nymphal population was
in the range of 2.39-9.67/leaf averaging 5.35/leaf. The total nymph
and adult white fly population was in the range of 3.54-14.32
averaging 7.92/leaf and peak population (14.32/leaf). Squash bug
adult population was in the range of 0.22-2.42/leaf averaging
1.42/leaf; while nymphs were in the range of 1.13-3.92/leaf averaging
2.52/leaf. The total squash bug population (nymph and adult) was in
the range of 1.35-6.28/leaf, averaging 3.93/leaf. The insect population
was 1.35/leaf, sharply reached at maximum (6.28/leaf) and then
decreased. | | Keywords : | | | Population, dynamics, whitefly, fruit fly, borer, Indian
