Three entomopathogenic fungi (Verticillium lecanii, Beauveria bassiana and Metarhizium anisopliae) along with two standard insecticides (acephate and chlorpyriphos) were evaluated for their effectiveness in the field of Bunny Bt (Cry IAC) cotton neem oil + detergent (Nirma) powder and detergent powder alone during 2007-08&2008-09 against two mealybugs viz., Phenococcus solenopsis and Paracoccus marginatus. The results revealed that B. bassiana, V. lecanii and M. anisopliae brought out a reduction of 39.1, 30.9 and 28.2 per cent incidence and 69.0, 59.0 and 23.1 per cent population of mealybugs respectively, while, the insecticides acephate and chlorpyriphos brought out a reduction of 93.8 and 87.1 per cent incidence and 97.8 and 95.3 per cent population, respectively. Detergent powder brought out a reduction of 51.7 per cent incidence and 82.4 per cent population, while detergent powder + neem oil brought out a reduction of 20.9 and 36.1 per cent, respectively. Observation on the activity of predators revealed that B. bassiana, V. lecanii and M. anisopliae brought out a reduction of 61.3, 51.6, and 6.5 % coccinellids and 33.7, 15.2&22.8 % spiders as against 54.8 and 42.4 % respectively in the standard insecticide acephate. Treatments with neem oil+ detergent powder and detergent powder alone did not reduce coccinellid population, however, reduced spider population by 22.6&13.0 percent respectively. All the treatments recorded significantly higher yield over control during 2008 - 09 and the increase in yield over control ranged from 18.0 to 43.0 %.Keywords

The papaya mealy bug, Paracoccus marginatus Williams and Granara de Willink, was recorded in severe form on cotton in Coimbatore in 2008-09. Infestation leads to drying of the sympodial branches and both Bt and non-Bt cotton hybrids have been observed to be infested. Spalgis epius (Westwood) (Lepidoptera: Lycaenidae) was recorded as a predator on P. marginatus infesting cotton and other hosts like papaya, silk cotton, subabul, Ixora sp., Crotons, Gliricidia sp. and Hibiscus sp. The larvae of S. epius were found to be voraciously feeding on the egg masses, nymphs and adults of the mealybugs.Keywords

A selective method of application of insecticide viz, 'Skip row coverage' has been employed against sucking pests in cotton. Skip row coverage with monocrotrophos (as alternate row or as alternate pair row) was as effective as full coverage against the leafhopper, Amrasca biguttula biguttula Ishida and the aphid, Aphis gossypii Glov. Deltamethrin, endosulfan and monocrotophos as skip row spray coverage harboured more population of the predator, Chrysoperla carnea (Steph), while monocrotophos, carbaryl and deltamethrin spared the predator, Menochilus sexmaculata (Fab.) by 2 .0 to 2.4, 1.6 to 2.2 and 1.2 to 2.8 times more than full coverage with the respective insecticides.Keywords

Foliar application of dlmethoate was relatively safe to the predator, Menochilus sexmaculata Fab, and was effective against the leaf hopper Amrasca biguttula biguttula Ishida from 28 to 52 days after sowing. Seed treatment with Carbofuran 40F was the next best and gave protection from the leaf hoppers from germination to 42 days after sowing and was also safe to the predator. Although soil application with aldicarb or carbofuran reduced the abundance of the predator, it was the most effective treatment for the aphid, Aphis gossypii Glov.Keywords
