insect and mite pests in sub-continent [20]. The cotton crop is attacked by 96 different types of insect pests and mite species during its growth period. These insects and other pests normally observed to nourish on fiber crop in Pakistan [21]. Mainly insect pests of cotton crops consisting of two groups depending upon their mode of damage, insects with chewing mouth parts and insects with piercing sucking type of mouth parts [22]. Chewing insects generally chewed the different parts of cotton plant including cotton bollworms and leaf worms etc. e.g. pink bollworm, American bollworm, armyworm, spotted bollworm, cotton leaf worm etc. Mainly the immature stage of this group damages to cotton crop [14, 22]. **Table 1** includes the major chewing pests of cotton crop as given below.

The other group of cotton pests include pests with sucking mouth parts. In Pakistan, India, China, Japan, Trinidad, Puerto Rico, Australia and Europe the key pests of cotton crop had sucking type of mouth parts are thrips, jassid, whitefly and they cause considerable loss in cotton production [35, 36]. Insects with sucking type of mouth parts became primary pests of cotton crop from the time transgenic cotton (Bt cotton) commercialized in the world [37]. **Table 2** includes the major piercing sucking pests of cotton crop as given below.
