Using diatomaceous earth and yellow soil as pesticide carriers, 19 insecticides were used to control Lixus subtilis Boheman of Chenopodium quinoa in laboratory. The results showed that 40% chlorpyrifos EC and 40% phoxim EC showed the quick-acting property and sustained performance, and the control effects reached 100% after 7 days, which was recommended for production. Using diatomite as the carrier, the control effects of 5% acetamiprid EC, 3.2% beta-cypermethrin·emamectin benzoate ME, 5% emamectin benzoate SC and 20% dinotefuran soluble granule were significantly improved, and the control effects were 100.0%, 100.0%, 73.3% and 95.8%, respectively, after 7 days of administration, which could effectively control Lixus subtilis Boheman of Chenopodium quinoa, and it was recommended to use the mixed application of insecticide and diatomaceous earth in production.
