The major arthropod pests and weeds of agriculture in Southeast Asia.


This book consists of the information gathered in a comparative survey of pests and weeds of importance in the 10 countries of South East Asia. A table of 455 species of arthropod pest initially identified as being of importance is provided. Their distribution is also tabulated, and a further table gives a measure of their importance in each country. Information on the origin or supposed origin of each pest is provided. At least 24 species were considered to be exotic to the region and are therefore potential targets for biological control. Bactrocera cucurbitae, B. dorsalis, Helicoverpa armigera, Heteropsylla cubana and Plutella xylostella were identified as the most important pests. Similar information is provided for the 233 species of weeds identified as important, of which 63 were believed to be exotic. Cyperus rotundus, Echinochloa colona, Eleusine indica, Imperata cylindrica and Monochoria vaginalis were identified as the most important weeds. Summarised lists of the most important pests and weeds on particular crops, and the yields of the crops for 1990, are presented. A checklist of preferred names for the arthropods is included.
