Ladybug egg-laying and collecting device capable of improving yield of ladybugs

Abstract

The invention discloses a ladybug egg-laying and collecting device. The device comprises an egg-laying outer chamber (1) and an egg-laying inner chamber (2), wherein the egg-laying outer chamber is a non-bottom conical cover, the egg-laying inner chamber is a conical cavity in the same shape with the egg-laying outer chamber, the egg-laying outer chamber is provided with a rectangular ladybug inlet and outlet I (3), and the egg-laying inner chamber is provided with a ladybug inlet and outlet II (5) in the position and the size which correspond to the ladybug inlet and outlet I (3); and the egg-laying inner chamber is nested in the egg-laying outer chamber, and the connection is carried out through connecting parts arranged at the top part of the egg-laying inner chamber and the top part in the egg-laying outer chamber. The device can lead ladybugs to climb into an egg-laying device by themselves when laying eggs and has the advantages of being free from the external interference, increasing the egg laying amount, leading the eggs to be difficult to be fed and the like.

Description

technical field [0001] The invention relates to a ladybug egg collecting device capable of increasing the output of ladybugs. Background technique [0002] No matter in the greenhouse or in the field, aphids are a kind of important agricultural pests, which have caused quite a lot of disasters. Ladybugs are predatory natural enemy insects with a strong ability to control aphids. They are one of the effective natural enemies for the prevention and control of various pests such as agriculture, forestry, fruit trees, and vegetables. The biological control measures for insect control can reduce the impact of chemical pesticides on the environment. Pollution and hazards to human health. At present, it is possible to artificially produce ladybugs on a large scale and release them to the fields to control the damage caused by pests to crops. [0003] Ladybugs had many technical difficulties in the artificial breeding process in the past, so that the production of ladybugs could n...

Problems solved by technology

[0004] 1) Ladybugs have the habit of eating their own eggs. In the process of mass feeding, the feed is mixed with ladybugs. When adults lay eggs on plants with aphids, ladybugs feed on aphids together with their own eggs. They are eaten together, and the eggs laid by ladybugs are easily polluted by insect secretions and excrement, so that the egg shells deteriorate and dry up due to water loss, which causes a lot of losses and the number of ladybugs obtained is very small

[0005] 2) The eggs produced by ladybugs live in the same environment as adult ladybugs and feed insects-aphids. In order to prevent the eggs from being eaten by ladybugs, the eggs must be collected several times (8-10) per day, and cut with scissors. Take or dip a brush in water to take out the eggs, although the loss of ladybug eggs is reduced, but this method is time-consuming and laborious, and often alarms the ladybugs, affecting the normal laying of eggs of ladybugs

[0006] The disadvantage of adopting the above method is that the collection of ladybug eggs is not complete. When the missed eggs hatch into larvae, the harm to the ladybug eggs is even greater. Different insect states are raised in the insect breeding box, and they occupy a large space. Interfering with each other in the position and range of activities, affecting their normal growth and development
