Cadavers of Phenacoccus solenopsis Tinsley were collected from locations in Haryana and Punjab during 2007-2010. The entomofungal pathogen, Fusarium pallidoroseum (Cooke) Sacc., was consistently isolated from all locations during three seasons. The recovery of the entomopathogen varied among locations and seasons. Koch's postulates were proved by reisolating the same fungus from infected mealybugs. In the laboratory, F. pallidoroseum caused 80-95% mortality of P. solenopsis.Keywords

Fusarium pallidoroseum was tested for compatibility with commonly used insecticides to include as one of the components of IPM for developing management strategy for cotton mealybug, Phenacoccus solenopsis Tinsley. In vitro compatibility studies of F. pallidoroseum with insecticides showed minimum inhibition of 17.9% with imidacloprid 17.8 SL (Confidor), followed by 32.4% with fipronil (Regent) and 36.0% with imidacloprid 24% flowable (Admire), while profenofos (Celcron) showed maximum inhibition (86.3%). The study indicated that imidacloprid (both formulations - SL and FS) and fipronil can be used for the management of the mealybug as these were relatively safer to F. pallidoroseum.Keywords

Studies were conducted during 2007 and 2008 over a considerable geographical area under cotton cultivation for finding potential natural enemies of Phenacoccus solenopsis Tinsley. In July 2008, large numbers of mummified P. solenopsis along with healthy mealybugs were observed on heavily infested cotton crop at Central Institute for Cotton Research, Regional Station, Sirsa (Haryana) due to parasitization by Aenasius bambawalei Hayat, a potential bioagent of P. solenopsis. The parasitoid completed its life cycle on the mealybug leaving the mummified body along with the exit hole behind. The parasitization efficiency of the parasitoid from field collected mealybugs was 57.2 per cent (range 46-64%) whereas under laboratory condition, it was 60.6 per cent (45-74%). As biological control is a supplement to chemical control, the adverse effect of commonly used insecticides on cotton on the efficiency of this parasitoid was studied and monocrotophos was recorded as the most deleterious (57.52% reduction in parasitization). Spinosad and spirotetramet were found to cause the least reduction in parasitization.Keywords
