abstract
Invasive insect pest are one of the major and most rapidly growing threats to agricultural biodiversity, forestry, human and animal health, etc. resulting in huge economic losses. Incidence of invasive insect pests such as Woolly apple aphid; Eriosoma lanigerum (Hausmann), San Jose scale; Quadraspidiotus perniciousus (Comstock), Lantana bug; Orthezia insignis Browne, Cottony cushion scale; Icerya purchasi Maskell, Potato tuber moth; Phthorimaea operculella (Zeller), Diamond back moth; Plutella xylostella (Linn.), Pine woolly aphid; Pineus pini (Macquart), Subabul psyllid; Heteropsylla cubana Crawford, Serpentine leaf miner; Liriomyza trifolii (Burgess), Coffee berry borer; Hypothenemus hampei (Ferrari), Spiraling whitefly; Aleurodicus disperses Russell, Silver leaf whitefly; Bemisia argentifolii Bellows, Blue gum chalcid; Leptocybe invasa Fisher & La Salle, Coconut eriophid mite; Aceria gurreronis Keifer, Papaya mealy bug; Paracoccus marginatus Williams & Granara de Willink, Cotton mealy bug; Phenococcus solenopsis Tinsley, Erythrina gall wasp; Quadrastichus erythrinae Kim, South American tomato leaf miner; Tuta absoluta Meyrick, Fall armyworm; Spodoperda frugiperda (J.E. Smith) has been noticed. The invasion of the pests in new areas sometimes lead to the outbreak of the pest due to lack of natural enemies. Therefore, exploration should be made in the areas of origin of the pests or efforts should be made to search some effective natural enemies in the invaded area so that the pest population could be curtailed with in Economic Threshold Level. These invasive insect pests can be minimized with the use of biological control agents or their natural enemies and quarantine set up need to be upgraded as this could result in the globalization of pests.
