Large leaf mint(Agastache rugosus),white clover(Trifolium repens),spearmint(Mentha spicata),tall fescue(Festuca elata),orchardgrass(Dactylis glomerata)and alfalfa(Medicago sativa)were selected to perform sod culture,and the repellent effects of different grass species on adult raspberry Drosophila melanogaster were studied,so as to provide a scientific basis for grass cultivation in the control of raspberry fruit fly.The study showed that spearmint and big leaf mint had strong repellent effects on raspberry D.melanogaster,with repellent effects reaching 81.25%and 72.73%,respectively,and could be promoted as the main plant varieties in grassing orchards;and the next was alfalfa and white clover,which had the average repellent effects of 50.57%and 34.94%on D.melanogaster,respectively,and could be used as nectar plants to supplement the ecosystem of the sod culture orchards. 展开更多

Creseote bush-based (Larrea tridentata Cov.) botanical insecticides have not been evaluated on pecan black aphid (Melanocallis caryaefoliae D.), the purpose of this research was to test the insecticide and/or repellent effect of the creseote-bush raw extracts on this insect. Ethyl acetate, methanol and water as solvents, the stem and leaf organs were tested at concentrations of 0.5%, 1%, and 2%, as well as their witnesses and the interactions of each. Extract application was made by immersion during 10 s and the incubation was made in a wet chamber, making observations at 24, 48 and 72 hours after the treatment was applied. Mortality was evaluated by touching the aphid and seeing it did not move, while for repellence the insects found outside of the leaf were taken into account. A higher mortality effect was observed at a 1% concentration for the three solvents on the leaf extracts, being the methanol one the most efficient, on the other hand the stem extracts had the same behavior, presenting the higher mortality in the ethyl acetate extracts at 0.5% and 2% both at 72 hours. On the other hand the higher repellent effect presented at 24 hours in stem extracts, with a variation in the leaf extracts. 展开更多
