Description

A device for trapping and rapidly collecting living Drosophila spotted wing

technical field

The utility model relates to the field of insect population dynamic investigation and control teaching, in particular to a device for trapping and quickly collecting live Drosophila spotted wing.

Background technique

Spot-winged Drosophila (Drosophila suzukii Matsumura), also known as Suzuki's Drosophila, belongs to the order Diptera, the suborder Annuli, the family Drosophila, the genus Drosophila, and the subgenus Drosophila. Drosophila spotted wing attacks a variety of berry and stone fruit types including blueberries, blackberries, cherries, strawberries, plums, peaches, grapes, figs, kiwis and pears. Spot-winged Drosophila likes to damage the cherries that are about to ripen. Its ovipositor is jagged, which can easily pierce the peel and lay eggs inside the intact fruit. The only visible damage on the outside is only tiny oviposition scars. The larva eats and eats, causing the fruit to completely soften, brown and even rot, which greatly reduces the yield and quality of the fruit. In the United States, Germany, Italy, France and other countries, the loss of some soft-skinned fruits caused by Drosophila spotted wing is as high as 100%. With the development of fruit tree planting and the increasing frequency of international trade, the government departments of countries (regions) such as the United States, Australia, New Zealand and EPPO have successively issued early warnings or included them in the list of quarantine pests.

In summary, in order to study the biological and ecological characteristics of Drosophila spotted wing and indoor breeding technology, develop its population monitoring and early warning technology, bioassay technology and pesticide safe use technology, etc., the acquisition of live Drosophila spotted wing is the premise and prerequisite for the research. Assure. At present, wild-type fruit flies are obtained by collecting the damaged fruits, waiting for them to hatch, raising them indoors until they become adults, and then breeding them. This method has the following disadvantages: whether the fruit is spawned or not is unknown, and the environmental conditions The change causes the hatching rate to be low, and adults need to be reared for one generation before they can be obtained. To a certain extent, it affects the progress of breeding. The purpose of the existing trapping device for Drosophila spotted wing is to trap and kill fruit flies. The collected samples are soaked in the trapping solution, and most of them are rotten and discolored, which causes inconvenience to the morphological identification of fruit flies and the development of molecular biology experiments.
