Luring and killing device for liriomyza sativae pests

Abstract

The invention relates to a luring and killing device for liriomyza sativae pests, belonging to the field of pest control. A mixture is prepared by the following components in percent by mass: 0.1-5% of isovaleraldehyde, 20-60% of hexenal, 4-25% of hexenol, 0.01%-8% of isoeugenol, 0.01-10% of matsutake alcohol, 10-60% of hexenol acetic ester, 0.1-8% of phenylacetic acid, 1-20% of ionone, 0.1-4% ofphenethyl alcohol and 0.01-5% of carvol; the mixture prepared from the components is dissolved in a normal hexane or dichloromethane dissolvent; the dissolvent is dropwise added on a rubber carrier; after the dissolvent is completely volatilized, a liriomyza sativae lure is formed; and the liriomyza sativae pheromone lure is pasted on a yellow insect-attracting plate manufactured by pest stickingglue and a base plate. The luring and killing device is mainly used for the prevention of liriomyza sativae and has the advantages of convenience in use, good inducing effect, long effective duration, safety, environment friendliness and the like.

Description

technical field [0001] The invention belongs to the field of pest trapping for pest control, and in particular relates to a trapping and killing device with a pheromone lure core for Liriomyza sativae and a yellow sticky insect board. Background technique [0002] Liriomyza is a Diptera, Agromyzidae, and Liriomyza genus. It is a polyphagous pest that seriously damages vegetables, ornamental plants and forage crops. It has successively broken out in Europe, America, Some islands in Oceania and the Arabian Peninsula and other regions, mainly with the spread of host plants and other media around the world, have seriously occurred in more than 30 countries and regions, causing huge economic losses, and there is a tendency to continue to spread. Listed as the most dangerous class of quarantine pests by many countries. [0003] my country first discovered it in Hainan Province in December 1993, and listed it as a domestic quarantine object in 1994. Subsequently, Liriomyza sativa...

Problems solved by technology

[0005] The current control of Liriomyza is mainly the spraying of chemical pesticides. For example, the insecticidal composition of chlorpyrifos and cyromazine with application number 02123814.6 has a better control effect on Liriomyza, but since Liriomyza has a host The characteristics of wide range, hidden damage, strong fecundity, and easy resistance to pesticides also bring greater difficulty to chemical control. Relevant studies abroad have shown that the effective period of new pesticides to control Liriomyza sativae can only last for 3 years at most Therefore, relying on chemical pesticides alone to control Liriomyza not only cannot effectively control its harm, but also destroys the natural balance between natural enemies and pests due to the large number of pesticides killing natural enemies, and the damage caused by Liriomyza will intensify

And the biological control means and green control technology of Liriomyza sativus include utilizing parasitic wasps to carry out biological control, utilizing black light, yellow board and sweet and sour liquid to carry out physical trapping, removing weeds and strengthening quarantine, etc., but the above-mentioned methods all have their own However, such as the high cost of feeding parasitic natural enemies, poor attractiveness of physical control, limited effect, and difficulty in quarantine, etc., it cannot meet the needs of today's control of Liriomyza sativae
