Abstract/ Executive Summary:

A survey was conducted on the insect and mites pests, and other problems related to litchi cultivation faced by litchi growers at a village-Mashimpur, known as a capital of litchi growing area in Dinajpur. Farmers' comments indicated that fruit borer Argyroploce illepida, leaf curl mite Aceria Iitchii and leaf-miners Acrocercops spp. were serious (major) pests where as leaf eating caterpillar, bark eating caterpillar Indarbela spp, snow scale insect Chionaspis sp, shoot borer Chlumetia transversa and lac insect lacca spp. were minor pest. Burning of skin of the fruits, falling down of very young fruits, lack of marketing facilities, lack of purity of insecticides and other agricultural impute, absence of flowering of some litchi plants are major problems of the farmers. Thirteen types of insecticides were used by the farmers and 66% of them used Ripcord WEe followed by Agromythine (32%), Basudin lOG (6%). Removal of mite infested plant parts during fruit harvesting is also done by some (21 %) farmers. Liquid organic fertilizer-the Ocojeam was used as vitamin by 36% farmers and Folimore PGR (Triacontanol) by 30% farmers. The highest 41 % farmers took advice (information) for the control of insect pests from the dealer of insecticides and fertilizers and 38 % farmers use their own experience for the control of insect pest.

Achievement/Findings:

Litchi mite and fruit borer were the serious pests of litchi; litchi mite reduced yield through affecting the photosynthesis but fruit borer directly affect the fruits and by reducing market price. So, it is necessary to develop integrated pest management to control the pests. Problems of the litchi farmers were lack of training facilities and marketing facilities; when, how and what types of insecticides used in the litchi growers. From the sources the following suggestion could be made- development of a market at Mashimpur village for marketing facilities, arrangement at least 15 days training of the litchi farmers, development of an agricultural extension office at Mashimpur village, supply of agricultural imputes at low costs and arrangement of loan without interest, if required
