Problems solved by technology

Since the adults of litchi pedicle borer do not have obvious dimorphism, the research on the sex identification characteristics of the pupae has never been involved. Therefore, the sex identification of this insect is mainly distinguished by dissecting the external genitalia. Although this method has high accuracy, it needs to kill the insects. body, the operation is also very complicated

Embodiment 1

[0015] Example 1: An example of male and female identification of litchi pedicle borers.

[0016] Experimental source of insects: Collect lychee fruits from the lychee orchard and bring them back to the laboratory. The temperature in the laboratory is 25±1°C, the relative humidity is 65–80%, and the photoperiod is 14:10h L:D. The ground fruit is put into a plastic basin with a length, width and height of 45cm × 35cm × 5cm. The surface of the basin is covered with a piece of corrugated paper, which is used to collect the pupae of the litchi pedicle moth.

[0017] Collection of different characteristics of male and female pupae: Use tweezers or dissecting needles to pick open pupae cocoons, collect 100 pupae, and observe the differences in the morphological characteristics of each pupae under a stereomicroscope. Whether the back of the 3rd section of the pupa is yellow according to the difference characteristics, and whether there is a genital hole in the 7th section of the vent...

Abstract

The invention discloses a rapid sex identification method for conopomorpha sinensis. The method comprises the following steps: collecting a pupa or an adult of conopomorpha sinensis: when the back surface of the third section of the conopomorpha sinensis pupa is yellow, the seventh section of the ventral surface is provided with a reproductive hole, the maxillary palp of the adult is sturdy and / or the ventral surface of the tail section of the abdomen is longitudinally cracked, the conopomorpha sinensis is male; and when the back surface of the third section of the conopomorpha sinensis pupa is not yellow, the seventh section of the ventral surface has no reproductive hole, the maxillary palp of the adult is thin and / or the ventral surface of the tail section of the abdomen has no cracking and end truncation, the conopomorpha sinensis is female. According to the method, the cost is hardly needed, the operation is very simple, and related researchers can completely master the method only by being slightly familiar with the four morphological characteristics.

Description

technical field [0001] The invention relates to the technical field of identifying male and female insects, in particular to a method for quickly identifying male and female litchi pedicle borers. Background technique [0002] Litchi pedicle borer is the most important pest of litchi and longan. It can drill and damage the host's tender shoots, flower spikes and fruits, especially prefer to damage the fruit. The rate of litchi and longan insects is 10% to 20% in general years, and it can reach 60% in severe years. %~90%, make litchi, longan industry suffer huge loss. [0003] Litchi pedicle borer was first reported in 1941 and has been studied for nearly 70 years. The morphological characteristics of adults, eggs, larvae and pupa have been described in detail. Since the adults of litchi pedicle borer do not have obvious dimorphism, the research on the sex identification characteristics of the pupae has never been involved. Therefore, the sex identification of this insect is...
