Regional selection of insecticides and fungal biopesticides to control aphids and thrips and improve the forage quality of alfalfa crops

The efficacies of biological and conventional chemical insecticides against two major insect pests of alfalfa (aphids and thrips) were compared in three sites across China’s alfalfa belt. In addition, the persistence of the residues of chemical insecticides in alfalfa and their influence on the quality of alfalfa hay were examined. Efficacy varied among the different biological and chemical insecticides. The chemical insecticides were significantly more effective than biopesticides in a short time-frame. The efficacy period of biopesticides was significantly longer than that of chemical insecticides, and the corrected mortality rate of aphids in all regions was above 50% at 14 days after application. The analysis of pesticide residues showed that the residual doses of all the pesticides were within the allowed ranges after the safe period. The acid detergent fiber and neutral detergent fiber contents in alfalfa hay were higher and the protein content was lower in chemical insecticide treatments than in biopesticide treatments in Hebei. The relative feeding value of alfalfa hay treated with Metarhizium anisopliae IPP330189 was the highest among the treatments. Compared with chemical insecticides, the yield of alfalfa hay was higher in the biopesticides treatments. Biopesticides show a stronger control effect on insect populations and also a better improvement in the quality of alfalfa hay than chemical insecticides. This study provides a basis for exploring and developing a comprehensive control regime for alfalfa insect pests in the different alfalfa-growing regions in China, and for reducing chemical insecticide usage and improving forage quality.     

Dietary intake of pesticide chemicals. Calculated daily consumption of pesticides with foods are discussed and compared with currently accepted values

Residues of chlorinated organic pesticide chemicals were commonly found in all diet samples and all food classes within samples except beverages at a daily intake of 0.0014 mg per kilogram of body weight. Meat, fish, and poultry were the major source of pesticide residues and, when combined with dairy products, account for more than half of the intake of chlorinated organic pesticide chemicals. Fruits, garden fruits, and grain foods each accounted for about 10 percent of the intake of chlorinated pesticides. The DDT, its two analogs, dieldrin, lindane, and heptachlor epoxide account for 85 percent of the total intake of chlorinated pesticides. A single pesticide, DDT, accounts for one-third of the total. There was no statistically significant change in frequency or quantities of these compounds during this study. Frequency and quantities of the 14 additional chlorinated pesticides were too low to be meaningful.
