Embodiment 1

[0015] Place diablo beetle lures containing L-isoleucine methyl ester and (R)-(-)-linalool active ingredients in the trap; before the diablo beetle's overwintering eclosion activities, place traps at a distance of 60 meters between traps ; Hang the trap in the field from 19:00 to 21:00 every night, the hanging height is 2m from the ground for peanuts, sweet potatoes, soybeans and other short-stem crops, and 15cm higher than the crops for high-stem plants such as corn and small trees; Investigate the situation of the lure of the dark gill beetle in the device, and record the number of test insects.

[0016] After beetle beetles are found somewhere, continue to monitor and if the number increases, the control period is 10 days after the first sight of black gill beetles; if the number is small and there is no obvious upward trend, no control is required.

experiment example

[0018] Apply monitoring method of the present invention, 2010 in Lianyungang, Jiangsu Province, Hefei City, Anhui Province (2 o'clock), 4 dark gill beetle traps that different plots are set up in Qingdao City, Shandong Province trap beetles, and 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 reflecting the 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 using a sex attractant to predict the occurrence of the black beetle. Background technique [0002] Grubs are the general term for the larvae of the Coleoptera Scarabidae, which are harmful underground all the year round and cause devastating damage to various lawns, crops and fruit trees. Diablo grubs are the dominant species that harm peanuts, soybeans, sweet potatoes, corn and other crops, accounting for more than 70% of underground pests. Adults Diablo beetles feed on the leaves of poplar, elm, pear and other forest trees. In recent years, the peanuts affected by it generally have a 20% reduction in production, 60% to 70% in severe cases, or even no harvest. According to five consecutive years of follow-up investigations in Shandong, Henan, Anhui, Hebei, Liaoning and other provinces, the annual loss of peanut production due to its hazards is mor...
