However, when the fruit tree grows to an adult state after planting and large-scale flowering and fruiting are started, most of the photosynthetic products are used for flowering and fruiting, so that measures for preventing insects and insects of the fruit tree are required at this time. For insects of fruit trees, most of the larvae produce soft reproduction on the land for planting the fruit trees, such as drosophila corpulenta, eggs of the insects are produced on branches and leaves of the fruit trees during the period of imagination of the insects, the eggs fall into the land along with dead leaves after autumn leaf fall, the eggs are hatched into larvae after the growth period, the larvae crawl onto the fruit trees, and the nutritional tissues such as leaves, flowers and the like of the fruit trees are gnawed and grow into the imagoes. The growth of the insects has low requirements on the growth environment, and the egg laying rate of the insects is high. The method for cleaning the insects by purposeless spraying of the insecticide in the larval stage has low cleaning efficiency, and a large amount of insecticide does not meet the requirements of modern green pesticides for the growth of fruits, so the insects need to be treated by researching the physiological state of the insects. Because the number of the crawling insects to the fruit trees is far from each other in different time periods in the crawling process to the fruit trees in the larval period, and because the outdoor temperature and the outdoor humidity in different time periods have influence on the normal physiological activities of the insects, the tree-climbing number of the insects in different time periods needs to be researched to control the time period for spraying the insecticide, so that the insecticidal rate is reduced to the maximum, the minimum insecticide is used, the maximum tree-climbing insects are killed, and the insecticidal efficiency is increased to the maximum. Moreover, for the pests such as the drosophila melanogaster, the growth condition of the larvae of the pests is controlled, and the effect of getting twice with half the effort on the deinsectization efficiency is achieved, so that the quantity of the larvae on the trees in different periods is researched, the larvae are prevented from getting on the trees, and the effect of getting good results on fruit trees is achieved. When the tree-climbing time of the insects is analyzed, interference of other crawlers similar to the physiological cycle of the crawlers is avoided due to the maximum capability, and when the tree-climbing time of one crawler is researched as much as possible, the other crawlers cannot generate large interference on the experimental result of the research of the insects.

Therefore, a fruit tree crawling pest catching and counting device needs to be designed, the number of the larvae of the crawlers in different growth periods like drosicha corpulenta kuwana is researched, the time for spraying the insecticide is further determined, the larvae can be effectively killed, and the larva killing efficiency is guaranteed. The device can effectually prevent the quantity of trees on the larva to make the larva can not destroy the nutritive organ such as leaf, flower of fruit tree, guarantee leaf, flower can have best living environment, thereby improve the output of fruit, the annual harvest of guarantee fruit grower. The device installation is simple, can satisfy when studying a reptile, and other reptiles are little to the interference of experimental result, and the time of going up the tree of the research reptile that the guarantee device can be better.
