Diversity and taxonomic studies of acridoid pests (Acridoidea: Orthoptera) of pulses from Uttar Pradesh, India

Abstract :

In the present study insect pest complexes on pulses has been observed and their association with host plant was investigated. The pest species infesting different parts of this legume plant were foliage, flower, pod and leaf. The status of these pests has been determined depending upon the rate of their feeding and extent of damages caused by them. Pulses are important food crops due to their high protein and essential amino acid content. Like many leguminous crops, pulses play a key role in crop rotation due to their ability to fix nitrogen. India is largest producer of pulses in the world with 25 per cent share in global production. Grasshoppers consume flower buds and especially early pods that results in yield loss and a delay in maturity due to delayed pod set. Adults and nymphs feed on green plant material, creating holes on leaves and pods pose the greatest threat to pulse production. All the seventy districts of Uttar Pradesh have been surveyed to collect the acridoid pests of pulses. Fourteen species representing fourteen genera of grasshoppers have been recorded belonging to three families, six subfamilies and two tribes
