Colored pepper is very popular in the market, but because of excessive pesticide residues from many diseases and insect pests from time to time, the Agricultural Experimental Institute (hereinafter referred to as "Agricultural Experimental Institute") found that releasing the natural enemy, small black flower stink bug, in the colored pepper field can effectively inhibit the number of key pest "thrips". In addition to colored pepper, including tomato, eggplant, melon, strawberry, melons, beans, red beans and so on, the greenhouse effect is obvious, and open-air cultivation can also be used. Now open technology transfer, including companies, farmers' groups and farmers can be open to apply.

Thrips endanger colored peppers and deploy their natural enemies, small black stink bugs, to control.

The agricultural test pointed out that "colored sweet pepper" is a high economic crop cultivated in new facilities in Taiwan, and thrips are the key pests harmful to colored peppers. An average of 2 thrips per flower will cause browning and withering of heart buds or flower buds of colored peppers, affecting flowering and fruiting, resulting in rough brown spots on the fruit. If the density of aphids is too high and secretes a lot of honeydew, it will form soot disease and pollute leaves and fruits. If these pests are not properly controlled, it will seriously affect the yield, quality and commodity price of colored pepper.

Lin Fengqi, associate researcher of the response team, said that the Agricultural Test Institute has studied the small black flower weevil for as long as 20 years, and in the past four years it has begun a study on IPM (integrated disease and pest control) for colored peppers as natural enemies. In the past six months, organic farmers in Liujiao Township of Chiayi County have been on the verge of waste cultivation of colored pepper gardens as experimental sites, and it has been found that the application results are good.

Experiments show that the southern small black flower stink weevil, which releases 4 to 8 birds per plant in the colored pepper facility, can control thrips and other small pests, and can suppress the occurrence of thrips when the density is maintained at 1 per flower. in addition, the mixture of vegetable oil and lime sulfur can also effectively control aphids and tea mites, and color pepper can be cultivated without the use of pesticides.

Lin Fengqi explains that the small black flower stink elephant is a local natural enemy in Taiwan. in the past, it was thistle mark star, which was not deliberately introduced from abroad, and it will not have an impact on the ecological environment or the problem of ecological adaptability. it has nothing to do with the "litchi stink elephant" that harms litchi and longan, and farmers can use it at ease.
