Description
Technical field
The present invention relates to infrared electronic technology and insect community monitoring field, be specifically related to oneInsect counting and kind note identification apparatus.
Background technology
The powerful fertility of insect can make it spreading in a big way and in region, everyNian Douhui causes the huge loss of crops. For guaranteeing agricultural output, often pesticide abuse,Bring serious pollution and harm not only to environment and ecology, and remain in agricultural productPesticide has also caused food-safety problem. Adult insect community reaches after peak value, just can give birth toWorm's ovum is also bred a large amount of newborn larvaes, and this one-phase is to pass through spraying insecticide Control pestsUnique stage. Therefore, want timely and appropriate discovery spraying insecticide, effectively control insect pest, closeKey is accurate Monitoring Insect Pest group scale, obtains time and the scale of insect pest outburst.
Be no matter ocular estimate traditionally and the manual counting method based on adhesive trap, still makeBy the worm monitoring system of the modern technologies such as Remote Spectra, radar, machine vision, all existSome problems, could not become in given area insect community and estimate the most frequently used effective method.In given area, estimate that at present the most frequently used effective method of insect community remains in conjunction with trapingThe infrared surface light beam sensing technology of trap.
