Problems solved by technology

At present, domestic and foreign biological control workers have carried out extensive research on the biological characteristics of paramecium and its control technology, but chemical control is still the main method. Most of them are covered by the hard outer skin, which makes it difficult for chemical insecticides to achieve the ideal control effect, but instead pollutes the fruit and the environment, causing harm to human health, and killing a large number of natural enemies, making it more difficult to control the damage of paramecium

Embodiment Construction

[0011] Make a lure device, use 1R.α-pinene with a concentration of 10^-3g / mL, 1-chlorooctadecane with a concentration of 10^-3g / mL, and 1,8- The volume ratio of eucalyptol is 2:1:16 and mixed evenly to form the adult attractant of red-ringed ladybug. Add 3ml of red-ringed ladybug adult attractant dropwise on the absorbent cotton, then stuff the absorbent cotton into a 10ml brown glass bottle and seal it to complete the production of the luring device. Store the luring device at -20°C for later use.

[0012] Field trapping: Two experimental forests with similar growth of persimmon trees, paramecia damage and distribution of red-ringed ladybug adults were selected as the experimental forest and the control forest respectively, with a distance of 1 km between the two forests. During the occurrence period of the red-ringed ladybug, pick a sunny day and hang the lure 1.5 m above the ground. The attractants were changed every day, and after 3 days, the number of red-ringed ladybugs...

Abstract

The invention relates to the technical field of forest pest control. A rodolia limbata motschulsky attractant is prepared by uniformly mixing the following components: 1R.alpha-pinene with the densityof 10<-3>g / mL, 1-chlorooctadecane with the density of 10<-3>g / mL and 1,8-cineole with the density of 10<-2>g / mL, wherein the installation volume ratio of the three substances is 2 to 1 to 16. The invention also relates to application of the rodolia limbata motschulsky attractant in forests. The rodolia limbata motschulsky attractant disclosed by the invention has the advantages of an obvious attractive effect on the rodolia limbata motschulsky, no toxicity or harm and no pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of deworming in forests. Background technique [0002] Drosichacorpulenta belongs to Hemiptera Hemiptera and Coccoidea Coccoidea. It is a herbivorous insect with a wide range of hosts and harms a variety of forest and fruit trees. It is extremely harmful to poplar, persimmon, jujube and peach trees in northern my country. According to observations, in Kaidong Village, Jishan County, Yuncheng City, Shanxi Province (110°54′15″E, 35°39′55″N, 557 m above sea level), Paramecia occurred many times on persimmon and poplar trees. Therefore, the prevention and control of paramecium is the key link to ensure the harvest of economic fruit forests such as persimmon trees. At present, domestic and foreign biological control workers have carried out extensive research on the biological characteristics of paramecium and its control technology, but chemical control is still the main method. Most of them are covered with a...
