Experiments with new low-toxicity insecticides against subcortical larvae of Cryptorhynchus and Saperda



Experiments with new low-toxicity insecticides against subcortical larvae of Cryptorhynchus and Saperda



Cellulosa e Carta 34(5): 29-34



Trials were performed between 1979 and 1982 to determine the effectiveness of 22 insecticides against newly hatched larvae of C. lapathi and S. carcharias, both of which are pests of poplars. Insecticide emulsions were sprayed on artificially-infested bark of 1-yr-old Populus sp. Results show that trichlorfon, which has been used for more than 10 yr against both insects, was one of the most effective and economical against C. lapathi.
