Liriomyza sativae attractant and application thereof

Abstract

The invention relates to a liriomyza sativae attractant and application thereof, and belongs to the field of preventing and controlling pests. The liriomyza sativae attractant comprises the following components in percentage by weight: 1 to 20 percent of carbohydrate, 5 to 40 percent of protein source, 0.1 to 5 percent of plant allelochemical, 0.5 to 20 percent of cue-lure, 0.01 to 10 percent of toxic component, 0.5 to 5 percent of emulsifier, 1 to 15 percent of water content regulator and 0.1 to 5 percent of antiseptic; and a semi-solid pasty attractant used for preventing and controlling the liriomyza sativae is obtained by adding water into the components and uniformly mixing the mixture fully. The attractant provided by the invention is a semi-solid paste, and can be directly applied to the inner side of an attracting bottle or locally sprayed by adding water, so that the attractant can be extremely convenient to use; and the attractant also has the characteristics of attraction of both male and female pests, good attraction effect, long duration and no harm to crops.

Description

technical field [0001] The invention belongs to the field of pest control, and in particular relates to an attractant for Liriomyza sativae and its application. Background technique [0002] Liriomyza americana belongs to Diptera, Agromyzidae, and Liriomyza. It is an important class of pests that cause serious losses to fruit and vegetable crops. It is an invasive alien species and belongs to the key quarantine Sexual insects. It is known that there are more than 500 kinds of Liriodidae insects, most of which use larvae to damage the leaves or rhizomes of plants. Occurs everywhere. Both adults and larvae can cause damage. The hosts include cucumber, tomato, eggplant, pepper, cowpea, broad bean, soybean, kidney bean, watermelon and more than 110 kinds of plants in 22 families. [0003] Liriomyza sativae has strong fecundity and great harm. In its distribution or endemic area, under normal circumstances, it can cause 30%-40% crop yield reduction, and in severe cases, even cr...

AI Technical Summary

Problems solved by technology

The surface of heavily damaged leaves is covered with white serpentine tunnels and engraved spots, and the quality and yield of plants will be greatly reduced, resulting in serious economic losses.

[0004] At present, the prevention and control means of Liriomyza sativae mainly contain, one, chemical insecticide, such as application number is chlorpyrifos and cyromazine insecticidal composition of 02123814.6 is better to the control effect of Liriomyza sativae, but there are pests in the use of chemical pesticides Resistance development, pesticide residues, affecting the quality of melons and vegetables, destroying the environment and ecology, seriously restricting the export trade of melons, fruits and vegetables, etc.

2. Prevention and control of Liriomyza sativus parasitoids. At present, the core technology of this method, such as large-scale breeding of parasitoids, is still immature, resulting in low parasitism rate, and spraying pesticides after the release of parasitoids will easily cause a large number of natural enemies to die, which will affect the control. Effect

3. Yellow insect traps are currently used to trap and kill pests. They are environmentally friendly, but they are not very attractive to Liriomyza sativae, and the control effect is not good.

4. Sweet and sour liquid trapping is the most commonly used green control method. However, this method has weak lure to Liriomyza sativae and short duration of effect. Frequent replacement is required, which is time-consuming and labor-intensive.
