The invention discloses application of a
beauveria bassiana strain to prevent and control of pests on food crops and application to preparation of a
pesticide for preventing and controlling the pests on the food crops. The food crops are paddy rice, beans, potatoes, highland barley,
broad beans or wheat; the pests are
lissorhoptrus oryzophilus, corn borers, thorn-sucking
insect whiteflies, aphids, pine caterpillars, grubs, locusts, potato beetles,
monochamus alternatus, termites, tea lesser leafhoppers and peach fruit borers; a culture method of the
beauveria bassiana strain comprises the following steps: inoculating the strain on a culture medium for culturing at the temperature of 25 to 30 DEG C for 5 to 10 days, and then obtaining activated
spore powder. The
beauveria bassiana strain disclosed by the invention has the advantages of high
spore-producing ability, good production character and high
growth speed; in addition, the
beauveria bassiana strain has the characteristics of high
toxicity, high insecticidal speed and environment friendliness; by using an insecticidal fungal preparation produced by the
beauveria bassiana strain, the number of the
population of the pests such as the
lissorhoptrus oryzophilus and the corn borers on the food crops can be effectively controlled.
