RESEARCHES ON BIOLOGICAL PEST CONTROL IN THE COUNTRY
A group of researchers made investigations on different ways of controlling namely plant
insect pest by our farmers in 13 provinces of the various regions, namely: Quezon, Palawan,
East Samar, Claveria (Misamis Oriental) Argao (Cebu) and Cotabato. The following are their
practices:
Tubli
Tubli (Derris) is a low bush that provides insecticides against plant lice, yellow aphids, flies, caterpillars, and ticks, fleas, chicken fleas and others.
This is known to be used as fish poison, as traditionally done here and in Indonesia, but this is not legal because it kills the big fishes and their offspring. Tubli is poison to cold blooded creatures like insect insects like insects and marine organisms.
PLANT PESTICIDES FOR RICE PESTS
Certain plants, not harmful to the environment or to the user, repel the black insect pests that
attack rice plants. Some of these are the tubli (or labnek) lagtang(or macasia) and the
makabuhay(derris).
