Construction of a Fine Netting Screen House for Exclusion of Insect Pests of Cucumber in Hawaii

Grantee: Ho Farms, LLC

Melon Flies (Bactrocera cucurbitae) silverleaf whiteflies (Bamisia tabaci), melon thrips (Thrips palmi), and pickleworm (Diaphania nitidales) are serious insect pests of commercial cucumber production. These insects will also attack and cause serious damage to long squash, pumpkin, watermelon, honeydew melon, bitter melon, cantaloupe, and zucchini. It is common that for an eight week cucumber crop could require as many as 12 to 15 sprays to control these insect pests. Additionally, melon thrips and silverleaf whiteflies are known to develop resistance to nearly all insecticides registered to control them. The project seeks to install a technology that has been proven to be effective in the mainland under temperate conditions but has not been put to such a test in a tropical climate where insect pest pressure is intense year round.

The objectives of this project are to 1) reduce pesticide use by excluding specific insect pests of cucumber; 2) to improve air quality in the area surrounding the production field by reducing pesticide application (versus open field cultivation); and 3) to determine the cost effectiveness of the system for commercial use for vegetable production in Hawaii.
