[EBOOK] FRIENDS OF THE RICE FARMER: Helpful Insects, Spiders, and Pathogens, B.M. Shepard, A.T. Barrion and J.A. Litsinger, IRRI

This booklet illustrates representative examples of some of the more common species of predators, parasites, and diseases of insect pests of rice. It can be used with the IRRI booklet Field problems of tropical rice, which provides information only on pest species.

Before intelligent decisions about pesticide applications can be made, it is necessary to be able to identify which insect species are pests and which are beneficial. The occurrence of beneficial organisms varies depending upon location, time of year, and crop cultural practices. Thus we made no attempt to rank the groups by their relative importance.

Scientific language has been minimized so that the descriptions can be more easily understood. The pictures will provide an easy way of identifying beneficial species and thereby help prevent unnecessary chemical treatments.

Like Field Problems, this booklet was designed to facilitate its easy and inexpensive translation and copublication in languages other than English. IRRl does not ask for payment of royalties or payments for translation of IRRl materials published in developing nations.
