Problems solved by technology

[0004] Since life table technology is mainly used to study the mechanism of insect population change, a large number of repeated experiments are required to increase the credibility of the conclusions. However, the current conventional test methods have low work efficiency and low tool utilization, which affects the ability to study small and medium-sized insects. efficiency

Embodiment 1

[0043] 1) Host plant cultivation: pea seeds are soaked in warm soup and treated with germination, then place 8-12cm high sandy soil in a pot with a length, width and height of 35-40cm*18-20cm*12-15cm, and place the germinated 36-42 seeds are sown in pots, watered, and cultivated for later use.

[0044] 2) Cultivation of phytophagous small and medium-sized insects: After the pea plants grow to the second-leaf stage, inoculate the leaves or plant stems containing various pea aphids together on the pea plants, and take out the leaves or plant stems after 2-3 days. Continue to cultivate to form a stable population.

[0045] 3) Breeding of small and medium-sized predatory insects: After the pea aphid forms a stable population, inoculate the seven-star ladybug to the pea plants that have formed a stable population of the pea aphid at a ratio of 1:100, and then raise them. During the feeding process, the pea plants were replaced in real time.

[0046] 4) Production of special petri...

Embodiment 2

[0056] First 3 steps are with embodiment 1.

[0057] 4) Production of special petri dishes: take a petri dish with a diameter of 10cm as an example: the height of a petri dish with a diameter of 10cm is generally 1.6-1.8cm, and the bottom area is 78.5cm 2 .

[0058] S1: Fold the filter paper with a diameter of 10cm in half (keep the same size as the bottom of the petri dish).

[0059] S2: Fold the half-folded filter paper 1.6-1.8cm along the diameter of the semicircle toward the top of the arc (keep consistent with the height of the petri dish).

[0060] S3: Fold the above half-folded filter paper again along the diameter of the semicircle toward the top of the arc, with the same height.

[0061] S4: The filter paper is unfolded to form two semi-ellipses with a partition with a height of 1.6-1.8 cm.

[0062] S5: Put the filter paper folded in step S4 into a petri dish, and cover the petri dish, so that two independent spaces are formed in the same petri dish.

[0063] S6: ...

Embodiment 3

[0072] 1) Host plant cultivation: Carry out warm soup soaking and germination treatment to broad bean seeds, then place 8-12cm high vermiculite in a pot whose length, width, and height are 35-40cm*18-20cm*12-15cm, and germinate 36-42 of the seeds are sown in pots, watered, and cultivated for subsequent use.

[0073] 2) Cultivation of phytophagous small and medium-sized insects: After the broad bean plants grow to the second-leaf stage, inoculate the leaves or plant stems containing each insect state Prunus pea on the broad bean plants together, and take out the leaves or plants after 2-3 days Stems, continue to cultivate to form a stable population.

[0074] 3) Breeding of small and medium-sized predatory insects: After a stable population of P. pea is formed, inoculate hoverflies at a ratio of 1:80 to broad bean plants that have formed a stable population of P. pea, and raise them. During the feeding process, the broad bean plants were replaced in real time.

Abstract

The invention discloses a feeding method of small and medium sized insects. The method includes the following steps: (a) separating a single culture dish into two or four independent spaces identical in size with filter paper to obtain a special culture dish; (b) putting a host plant leave in each independent space of the special culture dish in the step (a) with the back upward, choosing a phytophagous insect from a stable population in each independent space for feeding, changing the host plant leave on time, and recording reproductive output of the phytophagous insect in each independent space on time till the phytophagous insect dies; (c) respectively putting a predatory insect in each independent space in the special culture dish in the step (a), then respectively putting in 30-150 phytophagous insects for feeding, and recording feeding amount of every single predatory insect on time till the predatory insect dies. Through the feeding method, feeding time and feeding space are saved greatly when insect population growth and decline dynamic is researched with the life table technique.

Description

technical field [0001] The invention belongs to the field of breeding methods for small and medium-sized insects related to biological control, and in particular relates to a breeding method for small and medium-sized insects. Background technique [0002] Biological control is the use of natural enemies to control plant diseases, insect (mite) damage and weeds in farmland, or the use of parasites, predators, and pathogenic microorganisms to control harmful organisms. At present, the natural enemy insects used in my country include: Odonata, Mantis, Neuroptera and Coleoptera and more than 120 species in 19 orders, which are called "living biological pesticides". However, most pests occur early, damage for a long time, and the density increases with the increase of temperature. Natural enemies tend to follow the prey at a high density. It is difficult to use natural enemies to control the number of pests in the initial stage of pests. The purpose of growth, therefore, needs ...
