Resumo
During 1979/80 planting period a field test was performed to estimate the insecticides efficiency and adjust their doses in arder to control Antiaa:rsia gemmatalis and Pseudoplusia irwludens and also Piezodorus guildinii, Nezara viridula and Euschistus heJ>os.
For A. gemmatalis and P. incZudens control, the following insecticides were used:
Baeillus thuringienses, Carbaryl, Clorpirifos, decamethrin + S 339, Oimetoate, Endosulfan, Methyl Parathion , Monocrotophos and Triclorfon.
For stink bugs, the insecticides used were: Carbaryl. Cianamid AC 222 705, Decamethrin, Decamethrin + S 339 , Dimetoate, Endosu1fan, FHC 35001, Methyl Parathion, Monocrotophos, Permethrin, Phosalone + Parathion Ethyl and Triclor fon. The statistic design was the randomized blocks with four replications. The comtrol and estimation for the caterpi1ars were reà 1-i zed i n l. l" and 7 days after the insecticides application, and for Stink bugs were in 2 and 7 days after the insecticides applications.
The results are as follows: a) A, gemmatalis was sensitive to all products te§: ted;
b) for P. inc"ludens, the insecticide Clorpirifos g thyl, Methyl Parathion and Triclorfon didn 1 t show efficiency above 80% after seven (7) days application; for N. viridula and P. guildinii, the efficien cy of Monocrotofos, Methyl Parathion, Carbaryl and FMC 35001 was above 80%; ) Endosu1fan a nd Dimetoate showed excelent efficiency in control P. guildinii and E. heros.
