Riffat Sultana, Santosh Kumar and Durdane Yanar
The grasshoppers and locust are one of the very familiar groups of insects to mankind. They cause significant damage to crops and cultivators protect their crops by using different chemical pesticides which put harmful effects on the human as well as on environment. During current era biological control is recommended to reduce the numbers of insects in field. In the complex of biological control agents entomopathogenic fungi are more effective and most successfully utilized insect pathogen. In this respect Aspergillus, Beauveria, Metarhizium, Lecanicillium spp. are gaining importance in the crop pest control in recent years due to the simpler, easier and cheaper mass production techniques. Many entomopathogenic species registered world-wide for insect’s control but this practice is currently under consideration as a potential alternative to chemical insecticides for insects control in Pakistan. Present study focused on control of acridid because member of this group are major agricultural pests. They destroyed the rice, sugarcane, wheat, maize and fodder crops in everywhere. For control of this pest several pesticides of billion rupees are used indiscriminately in every year. So, there should be suitable, beneficial and cheap alternative of these poisonous chemical. For this purpose the biological control is very important therefore, an attempt was made to introduce pathogenic fungi, against the reduction of acridid population in Sindh.
