Embodiment 2

[0048] The Y-type olfactory instrument was used to measure the directional behavior response of the mango cut leaf weevil to the mixture (improved by our laboratory based on the basic principle of the olfactory instrument, the authorized patent number is: ZL201020239767.7). The main arm of the Y-shaped tube is 20cm, the length of the two arms is 10cm, and the angle between the two arms is 90°C. At the ends of the tubes of the two arms, silicone tubes were used to connect the distilled water bottle and the activated carbon bottle in sequence. Finally, the activated carbon bottle was opened in the atmosphere, and the insect release bottle was connected to the suction device with gauze. Cut the filter paper strip into 5cm×1cm, fold it into a "V" shape, and place it in the trap inlet glass tube. Take 100 μl of the mixture obtained in the above step 1.2 and drop evenly on the filter paper strip and put it into the flavor source bottle on one side, and use the filter paper dripped w...

Abstract

The invention discloses a mango cut-leaf weevil attractant and a preparation method thereof. Using liquid paraffin as a solvent, 100 μg / ml of valencene, β-myrcene, terpinolene, β-caryophyllene, Omarene, α-farnesene, (1R)-(+)-α-pinene and trans-2-hexenal are mixed with the same quality. The attractant is a specific component screened from host plants, and has the characteristics of long-lasting effects and strong targeting. The attractant can make the adult mango leaf-cutting weevil quickly enter the target trapping area, and cannot escape from the target trap. Both females and males are killed together. It is of great significance to reduce its field population, improve the control effect of mango leaf-cutting weevil, and develop green, safe and sustainable pollution-free technology.

Description

technical field [0001] The invention belongs to the technical field of biological control of fruit tree pests, and in particular relates to an attractant for mango cut-leaf weevil and a preparation method thereof. Background technique [0002] mango( Mangiferaindica Linn.) Leaf-cut weevil ( Deporaus marginatus Pascoe), also known as mango leaf-cutting weevil, belongs to Lepidoptera Noctuidae. It is the main pest of mango young leaves. The generation overlap is serious. Both male and female adults feed on mango young leaves, especially the female adults are accompanied by leaf cutting during the process of laying eggs. behavior, affecting the growth of mango trees. In view of the increasing resistance of leaf-cutting weevil, there is still no efficient and environmentally friendly means of prevention and control. The control effect of traditional agricultural control is limited, and it is easy to pollute the environment (KumawatMM, SinghKM.Populationdynamicsandmanagementof...
