Embodiment 1

[0028] Such as Figure 1-3 Shown, a kind of predatory ladybug ovum collection method comprises the following steps:

[0029] 1) Raising a stable population of predatory ladybugs: raising the predatory ladybugs collected in the field under indoor conditions, and after laying eggs, move the egg mass to an insect breeding device for continuous feeding until a stable population is formed, and set aside for use;

[0030] Described predatory ladybug is any one of seven-spotted ladybug, heterochromia ladybug, polyheterotype ladybug, and tortoiseshell ladybug;

[0031] Described indoor condition refers to temperature 24-28 ℃, light intensity 0-3000lx, light cycle L:D=12:12, light source type is LED;

[0032] 2) Collection of predatory ladybug eggs: pick a pair of female and male predatory ladybugs from the stable feeding population of predatory ladybugs, put them into a petri dish containing bedding materials, add sufficient food, and observe the eggs produced at a fixed time every d...

Embodiment 2

[0039] Embodiment 2, the manufacture of the petri dish containing filter paper: take the petri dish with a diameter of 9 cm and the qualitative filter paper with a diameter of 11 cm as an example: the height of a petri dish with a diameter of 9 cm is generally 2.0-2.2 cm, and the bottom area is 63.59 cm 2

[0040] Spread a filter paper with a diameter of 11 cm on the bottom of the petri dish so that the inner wall of the bottom of the petri dish is covered by the filter paper, and cover the petri dish to make it.

Embodiment 3

[0041] Embodiment 3, the collection of predatory ladybug ovum: drop a pair of male and female ladybugs into a petri dish containing filter paper, and add a large amount of bean aphid therein for its feeding, observe at a fixed or random time every day, and find that its production After ovulation, the entire filter paper is removed from the petri dish, and new filter paper and bean aphids are added to allow it to continue laying eggs for centralized collection. According to the demand for egg masses, several identical petri dishes can be made for centralized collection of egg masses. Collect the filter papers containing egg masses in one place for collection.

Abstract

The invention discloses a method for acquiring and collecting egg masses of predatory ladybirds. The method comprises steps of feeding a stable population of the predatory ladybirds, acquiring eggs ofthe predatory ladybirds, manufacturing a culture dish containing a bedding material and collecting the eggs of the predatory ladybirds. A device for acquiring and collecting egg masses of predatory ladybirds comprises a circular base, a plurality of base grooves are formed in an upper surface of the circular base, one end of a first support rod is connected with one end of a second support rod through a bearing, the other end of the second support rod is fixedly connected with one end of a third support rod, the other end of the third support rod is clamped with an annular cutter head, the other end of the first support rod is fixedly connected with a bottom surface of a boss, the boss is positioned in an inner cavity of the first support rod, and the bottom surface of the boss is elastically connected with the circular base through a spring. The method and the device provide efficient, convenient observation recording and statistical method for researching egg-laying quantity and egg-laying habits of the predator ladybirds under different environmental conditions, and have advantages of simple operation, high efficiency, low cost and the like.

Description

technical field [0001] The invention relates to a device for collecting predatory ladybug egg masses, belonging to the technical field of biological research. Background technique [0002] With the development of modern agriculture, problems such as environmental pollution, ecological balance and pesticide residues brought about by agricultural production are restricting the sustainable development of agriculture and affecting the living environment in rural areas. At the same time, with the continuous improvement of people's living standards, the requirements for the refinement and quality of agricultural products are more stringent, forcing agricultural production to change from extensive management, relying on chemical fertilizers and pesticides to fine-grained policies, and green prevention and control. The rapid development of modernized agriculture and urban agriculture in first- and second-tier cities has made the market for the use of biological control methods to ef...
