Discussion
on wheat crop Insect biodiversity earlier was not considered as a
harmful element, but due to the recent changes in climate and
introduction of new varieties several insects are recorded on wheat crop
in district Haripur, there was a big loss to wheat crop this year due to
attack of armyworm Some insects are common visitors of wheat crop
including aphids, but they usually been under check by their natural
enemies as they voraciously fed by coccinellids and Chrysoperla. In
present study only the identification of insect pest species were
considered. The crop has two critical periods of being attacked by
insects’ first headling and other is flowering phases
[9]. Thirps have been recorded to
cause damage [10]. But no thirps have
been recorded here so for. Leafhoppers are known as bio indicators and
include about 20000 species
worldwide[11]. The majority of
leafhoppers found on cereals and some are vector for viruses
[12]. In present research grasshopper
species acrida exaltata under family Acrididae has been found
