Embodiment 1

[0015] Place the traps containing L-isoleucine methyl ester and (R)-(-)-linalool active ingredients in the dark gill beetle sex lure; before the dark gill beetle overwintering eclosion, place the traps at a distance of 60 meters between the traps ;Hang the traps in the field from 19:00 to 21:00 every night. The hanging height is 2m above the ground for short-stalked crop fields such as peanuts, sweet potatoes and soybeans, and the high-stalked plant fields such as corn and small trees are 15cm higher than the crop; Investigation of the lure of the dark gill beetle in the vessel, and record the number of test insects.

[0016] After the beetles are found somewhere, continue to monitor if an increase in the number is found, the control period is 10 days after the first sighting of the beetles; if the number is small and there is no obvious upward trend, the control is not required.

experiment example

[0018] Using the monitoring method of the present invention, four dark-gill beetle traps were set up in different plots in Lianyungang, Jiangsu Province, Hefei City, Anhui Province (2 points), and Qingdao City, Shandong Province in 2010. The results are as follows.

Abstract

The invention discloses a method for monitoring holotrichia parallela by utilizing a sex pheromone, comprising the following steps: placing a holotrichia parallela sex lure into each trapper; placing the trappers in the field according to a certain distance before the holotrichia parallela overwinters to adult and comes up out of the soil; surveying the quantity of the holotrichia parallela collected by sex lures in the trappers; and recording the quantity of the test insects. The method provided by the invention solves the problem of inaccurate holotrichia parallela monitoring methods, trouble and lag and the like in the current production, and has the advantages of being simple and convenient in operation and accurate in monitoring and possessing the capability of objectively reflectingthe regularity of occurrence and development of the holotrichia parallela and the like.

Description

Technical field [0001] The invention relates to a method for predicting and forecasting insects, in particular, to a method for forecasting the occurrence of dark gill beetle by using sex attractant. Background technique [0002] Grubs are the general term for larvae of the Coleoptera superfamily. They endanger underground all year round, causing devastating damage to a variety of lawns, crops and fruit trees. The dark grub is a dominant species that harms peanuts, soybeans, sweet potatoes, corn and other crops, accounting for more than 70% of underground pests. The adult dark grub feeds on the leaves of poplar, elm, and pear trees. In recent years, the production of peanuts that have suffered from the damage has generally been reduced by 20%, severely reduced by 60% to 70%, or even no harvest. At the same time, the quality of peanuts has also decreased significantly, and the peanuts and shells have increased greatly. According to five consecutive years of follow-up investigatio...
