Potato growers in Idaho, Oregon and Washington are facing new insect pests that pose significant management challenges. Managing Insect Pests of Potato E-6-W 2 Figure 1. the common foliar wetland pests. Pest infestations can be identified by the type of damage done and by direct observation of insects. Insect Pest Management in Potato Potato production in Maryland continues to grow and has more than doubled in the last 5 years, while in surrounding states it has declined. Among those cut worm Spodoptera litura, potato tuber moth Phthoromea operculella and greasy cut worm Agrotis ipsilon were found as major insect pests. The most common aphid found on potato is the green peach aphid, an important vector of potato leaf roll virus (PLRV). When they are fully grown, they look like caterpillars in pink or in pale green color. Their life cycle includes eggs, larvae, pupae and moths. Insecticides are increasingly useless as the beetle evolves resistance. The important leaf-feeding caterpillars are Spodoptera spp. In storage, dry leaves of Eucalyptus, Lantana, Ageratum, Eupatorium, soapnut, and wheat straw offer significant reduction in infestation. D. Senior Scientist (S3) Prem Nidhi Sharma, Ph. The susceptibility of CIPC decreased with increasing larval age. The important leaf eating caterpillars are Thysanoplusia orichalcea, Spodoptera spp. Sweet potatoes should be planted in full sun and require plenty of space as the vines will spread over large areas. Losses (5–71%) were highest in the sites with the smallest rice area in which pests were concentrated and the poorest soils (which constrain yield compensation) along a continuum of dryland rice habitats. Colorado potato beetle eggs, 3.7 larvae, and 5.1 adults during development of instars 1-5. However, a proper insect pest management program will minimise losses to potato crop.

CIPC is helpful in reducing losses due to sprouting, but it also indicates very good potential against P. operculella in storage. Since 2012, psyllids have become the cornerstone insect pest of potatoes throughout the PNW. Many growers at risk of potato psyllid are designing their insect management programs around psyllid management strategies and fitting in control of other insect pests. However, commercial formulation of B. thuringiensis (Dipel 8L) and neem (Achook 300 ppm azadirachtin) did not afford good protection. Partitioned-growth-stage yield loss studies revealed the highest losses in dryland rice were due to sown-seed and seedling pests (ants, field crickets, mole crickets, and termites) as well as root feeders (white grubs and root aphids) and early seedling pests (seedling maggot and flea beetle) more than, India has a great diversity of insect pests attacking potato. �ꇆ��n���Q�t�}MA�0�al������S�x ��k�&�^���>�0|>_�'��,�G!
