Description

Be applied to pest selection device of laying eggs that indoor test carried out quick screening

Technical Field

The utility model belongs to the technical field of agricultural pest control, concretely relates to be applied to pest selection device of laying eggs that indoor test carries out quick screening.

Background

The egg laying selectivity of an insect may reflect the interrelationship between the insect and the host plant. Suitable host plants provide a good source of food for the larvae, maximize population fitness, and provide conditions for pest outbreak damage. The insects search for the host plant not only for feeding the host plant tissue, but also for simultaneously using the host plant as a place for survival, rest, shelter, mating and spawning. The complex interrelationship between phytophagous insects and host plants is formed during long-term evolution and mainly involves both the selection of the host plant by the insect and the resistance of the host plant to the insect. The utilization of host plant resistance is an important measure for comprehensive control of pests, and physical resistance is an important component of the pest resistance of host plants. The characteristics of plant leaves, fruits and the like are closely related to the damage degree of pests. Related researches find that the oviposition selectivity of insects is influenced by the species of fruit trees with different hosts, and the physical characteristics of the fruits with the same species and different varieties, such as size, hardness, villus, color and the like, also influence the oviposition selectivity. The oviposition selectivity relationship between insects and host plants is determined, and the method has important significance for guiding the directional spraying of the field ovicide, the establishment of control indexes, the breeding of insect-resistant varieties, the selection and the matching of fruit tree cultivated varieties and the like.

The development of a pest oviposition selection test in the field needs a layout test 1 year or even many years in advance, the period is long, the effect is slow, and due to the limitation of the test area, the screening of large-area, various types and varieties is difficult to develop. The mass screening in the initial stage by using the indoor test is beneficial to shortening the test period and reducing the test cost. How to design an oviposition selection device applied to indoor tests for rapid screening is a bottleneck of tests of related tests at present, and references are provided for pest control, variety breeding, selection and matching of fruit tree cultivation and the like.
