Problems solved by technology

For example, artificial eggs of Trichogramma are used to raise the seven-spot ladybug, although the survival rate has been improved, but after several generations of continuous feeding, the adults no longer lay eggs and lose their reproductive ability.
The artificial breeding of ladybugs also has the same problem. Ladybugs have a long egg-laying period, low egg production, and low egg hatching rate.

Embodiment

[0014] First, select the cotton field ridge or the surrounding tree forest belt, and place several trap boxes with equal gaps on the surrounding surfaces of the box respectively on the field ridge around the cotton field or hang them on the surrounding tree forest belt or corn trapping belt of the cotton field; Put pollen or honey and perch paper or leaves or weeds in the collection box to attract ladybugs, and fix shelter paper or various soft cloths on the upper edge of each gap around the trap box; The insect traps are stored at a low temperature of 0-10°C or released as seed scoops to farmland with aphid hazards at any time for prevention and control. In 2002 and 2003, the trapping experiments were carried out in cotton fields, as shown in Table 1:

[0015] Wood

[0016] The results showed that in 2002, the average number of 11-spot ladybugs caught in the corn trapping belt beside the cotton field was 391 heads / box and 304 heads / box for the treatment and control...

Abstract

The present invention relates to a method for artificially trapping coccinella undecimpunctata for controlling aphides. Said method includes the following steps: firstly, selecting bund of cotton field of peripheral woods belt, making trapping box whose four sides are equipped with uniformly-distributed slots respectively, placing several trapping boxes on the bunds around cotton field respectively or hanging these trapping boxes from peripheral woods belt or corn trapping strip, placing pollen or honey and roosting paper or tree leaf or weeds into the trapping box to attract coccinella undecimpunctate, storing the trapped coccinella undecimpunctate at low temp. of 0-10 deg.C to make hibernalisation, also can use the coccinellids as seed ones and release then to control aphides. Said invention not only can breed coccinella undecimpunctate, but also can be used for controlling aphides.

Description

technical field [0001] The invention relates to the field of biological control, and relates to a method for artificially trapping ladybugs to control aphids. Background technique [0002] Usually, the techniques of utilizing ladybugs to prevent and control pests mainly include: 1. Protecting growth and artificially assisting ladybugs to prevent and control farmland pests. Increase the number of ladybugs by intercropping crops or planting trees and grasses around the farmland, and move them to the farmland with aphid damage by netting or other artificial capture methods, so as to achieve the purpose of controlling aphid damage by field ladybugs. The more studied ones are the seven-star ladybug and the multi-different ladybug. 2. Introduce and transplant beneficial ladybugs to control orchard pests. At present, my country has introduced 3 species of beneficial ladybugs from abroad, namely: Australian ladybug, Cryptidia monsonii and little black ladybug...
