Device and method for acquiring Carolina Sasakii Matsamura summer cocoons and over-wintering cocoons in batch

Abstract

The invention discloses a device and a method for acquiring Carolina Sasakii Matsamura summer cocoons and over-wintering cocoons in batch. The device comprises a net house, the net house comprises a support and a thin net wrapping six external surfaces of the support, an isolation layer, a cocoon layer and a bored fruit layer are sequentially arranged on the net house from bottom to top, the boredfruit layer and the cocoon layer are separated by a bored fruit separation net, the cocoon layer and the isolation layer are separated by a cocoon separation net, the isolation layer and the cocoon layer are filled with river sands, a bored fruit release opening is formed in the bored fruit layer, a cocoon taking-out opening is formed in the cocoon layer, and a moisturizing layer is further arranged on the upper portion of the bored fruit layer. After insect borne fruits with uniform bored fruit periods and without pesticide application are collected, the insect borne fruits are placed into the device in a centralized manner at time intervals. According to the method, a large quantity of batched and evenly developed insect borne materials with good physiological status consistency and without being affected by chemical pesticides can be provided for intensive study of biology, physiology, ethology, genetics and ecology of Carolina Sasakii Matsamura, and particularly, the technical field of comprehensive control.

Description

technical field [0001] The invention relates to the technical field of research on comprehensive prevention and control of the small peach borer, in particular to a device and method for obtaining summer cocoons and overwintering cocoons of the small peach borer in batches. Background technique [0002] Peach borer ( Carolina Sasakii Matsamura), belonging to Lepidoptera (Lepidoptera) family Carposinidae, is one of the largest and most harmful borer pests in fruit tree production in northern my country. The small peach borer eats fruit with larvae. It mainly eats pome fruits and drupe fruits such as apples, hawthorns, and jujubes. value. [0003] Fruit bagging is one of the main measures to control peach borer, but in recent years, under the transformation and upgrading of the apple industry, cost-saving, quality-enhancing, and environmental-friendly demands, the limiting factors of bagging technology in the modern production of apples ( Fruit bags consume too much paper,...

Problems solved by technology

[0005] (1) The peach borer has 2~3 generations a year. During the eclosion period of the adult peach borer, the female lays eggs on the surface of the fruit or the back of the leaf, and crawls for a few minutes after hatching to eat the fruit; It is relatively short, so it is difficult to catch, even if a small number of larvae are caught, it is difficult to carry out research experiments due to inconsistent ages;

[0006] (2) Peach borer overwinters as mature larvae forming oblate cocoons in the soil. The depth of overwintering can be at the surface of the soil at the shallowest level, the deepest can reach 15 cm, and the depth of 3-8 cm is the most. The distribution range of the overwintering larvae Mainly within 1 meter around the trunk, but artificially dug overwintering cocoons. First, the amount of overwintering cocoons obtained is small, which cannot meet the needs of later experiments. The applicant has used this method for two consecutive years, but failed to obtain an ideal number of overwintering cocoons. The second is that due to the inconsistency of the fruit moth period, the mature larvae in the overwintering cocoon have irregular growth and development, and the physiological state is inconsistent, which cannot form a good test sample, which has a great impact on the research results and makes the research results meaningless.

[0008] It can be seen that it is very difficult to obtain the larvae of the small peach borer in batches from the field, and the larvae obtained by collecting overwintering cocoons have large individual differences, which is not conducive to later research. Therefore, in order to study the effective comprehensive control of the small peach borer method, there is an urgent need for a method that can obtain batches of larvae with neat development and consistent physiological state in the field
