摘要

Insect pests are a major constraint to the production of many food crops in PNG. With the human population growing rapidly in many areas of PNG, pest problems are likely to increase further. Recent surveys have shown that the impact of a variety of pests is rising rapidly and disastrous losses are increasing, especially in adverse environmental conditions and areas of dense human population. The use of commercial insecticides is net a solution for most farmers in PNG, as they lack financial resources and the necessary technical expertise to use insecticides economically and safely. Homemade water extracts of local plants can be a more appropriate form of pest control. This paper presents results of trials conducted on the Gazelle Peninsula in East New Britain Province, using head cabbage (Brassica oleracea var. capitata (L.)) and aibika (Abelmoschus manihot (L.) Medik.). The effect of plant-derived pesticides (PDP) and commercial insecticides on pests, beneficial insect and arachnid species, yield and produce qualities are described. Additional information is given on the production and use of various PDPs.
