Problems solved by technology

[0004] Through a large number of studies, it has been found that the kidney bean pods are also very suitable for laying eggs of the southern flower bug. Not only do they have advantages in material collection and preservation, but also the hatching rate of the eggs of the southern flower bug can reach more than 80%. It is a rare egg-laying medium plant, but Also there are several disadvantages: 1) the pod size (about 20cm in length and about 2cm in width) is larger than other spawning medium plants, and there are not many materials for laying eggs in the limited space. If too many pods are placed, the Because the pods are superimposed on each other, the parts that can be used for laying eggs of the southern flower bug will be virtually lost; 2) in the process of breeding the worm body in the later stage of the egg-bearing pods, due to their size, it is easy to crush the nymphs during the turning process; 3) In terms of refrigeration, the size of pods will also cause inconvenience in storage space. If eggs are used as products, it will also affect the later packaging and transportation

preparation example Construction

[0025] The invention provides a method for preparing the egg-laying medium of the southern flower bug, which comprises the following steps:

[0026] 1) cross-cutting the whole kidney bean pod to obtain the tip of the pod;

[0027] 2) melting solid paraffin to obtain liquid paraffin;

[0028] 3) immerse the incision at the tip of the bean pod in step 1) into the liquid paraffin described in step 2), seal the seal, and cool to obtain the egg-laying medium of the southern flower bug;

[0029] There is no chronological order limitation between said step 1) and step 2).

[0030] In the present invention, the position distribution of the whole kidney bean pod is as follows: figure 1 As shown, where M represents the middle of the pod; T represents the tip of the pod; H represents the head of the pod; S represents the pod surface; G represents the pod seam.

[0031] The present invention preferably also includes cleaning and air-drying the whole kidney bean pods before cross-cuttin...

Embodiment 1

[0048] Embodiment 1 A kind of preparation method of the medium for laying eggs of the southern flower stinkbug

[0049] 1. Cleaning of kidney bean pods

[0050] Select kidney bean pods with no damage on the surface and complete bean tips, place them in 2L of clean water, add 0.15mL of dish soap, and then rinse. Hold the pods firmly in the water and rinse them up and down repeatedly for 30 seconds. Lift the pods completely and rinse them under tap water for 15 seconds. This process is to wash off the chemicals left on the surface of the pods.

[0051] 2. Drying of washed kidney bean pods

[0052] Spread the washed pods on the filter paper one by one, use an absorbent paper towel to gently wipe off the water droplets on the pods, and then use Midea electric fans on both sides of the pods to blow air, and the pods must be positioned in the direction of the wind to ensure that the pods The gaps are dry, the blowing time is 30min, and the temperature is 28°C.

[0053] 3. Cut the...

Embodiment 2

[0057] Example 2 verifies the freshness of the southern stinkbug spawning medium of Example 1

[0058] Place the above-prepared egg-laying medium of the southern flower bug and the same number of pod tips and whole bean pods under the environmental conditions of 27±1° C. and 70±5% humidity, and observe the egg-laying medium and the whole body of the southern flower bug. The freshness of the root pods was repeated 10 times for each treatment. See Table 1 for the comparison results, and the results show that the egg-laying medium in Example 1 is basically similar to the freshness of the whole kidney bean pod.

Abstract

The invention provides a preparation method and application of a southern orius insidiosus spawning medium, and belongs to the technical field of insect rearing. The preparation method comprises the following steps that 1, whole kidney bean pods are transected, and pod tips are obtained; 2, solid paraffin is molten, and liquid paraffin is obtained; 3, cuts of the pod tips obtained in step 1 are soaked with the liquid paraffin obtained in step 2, sealing is performed, and cooling is performed to obtain the southern orius insidiosus spawning medium; no time sequence limit exists between step 1 and step 2. The obtained southern orius insidiosus spawning medium is good in heat preservation effect, and no adverse effect is caused to the egg quality and egg incubation rate; more importantly, byadopting the southern orius insidiosus spawning medium, the egg laying amount of southern orius insidiosus can be increased.

Description

technical field [0001] The invention relates to the technical field of insect rearing, in particular to a preparation method and application of an egg-laying medium of the southern flower bug. Background technique [0002] Orius similis (zheng) is a dominant species in southern my country. It has strong predation ability and has obvious control effects on thrips, aphids, spider mites, whiteflies, leafhoppers, Lepidoptera pest eggs and newly hatched larvae. , is a class of predatory natural enemies with broad application prospects. The southern flower stinkbug likes to lay eggs in the fresh and tender parts of plants. The new shoots, young leaves, flower buds and other materials of plants such as melons and beans can be used as the oviposition substrate for adults when they are reared. [0003] At present, there have been a large number of researches on the selection of oviposition substrates of the small flower stinkbug at home and abroad. For example, Murai (Murai T, Narai...
