The invention provides feed for larval coccinella septempunctata. The feed includes the following raw materials: egg, raw pork liver, water, milk powder, oat and yeast powder. The preparation method of the feed includes: (1) firstly cutting the raw pork liver into strips with a cutter, and then performing mashing into mud; (2) adding boiling water to soak the oat to soft; (3) adding the raw materials into a beaker, stirring the materials evenly with a stirrer, additionally weighing and adding agar and water into a pot, putting the pot on an electromagnetic oven to melt the agar, cooling the agar, then pouring the molten agar into the evenly stirred materials in the beaker, then fully stirring the substances, performing subpackaging in a culture dish, conducting sealing with a sealing film,and putting the product into a refrigerator for preservation. The invention has the advantages that after application to feeding of larval coccinella septempunctata, the feed can make the weight, pupation rate and eclosion rate of the larval coccinella septempunctata approach the level of those fed by aphids, is more beneficial to the maturation of larvae to adults, also the preparation method ofthe feed is simple, and is easy for large-scale operation, and the feed is easy for storage and large-scale popularization.

The invention discloses a ladybug attractant of an aphid natural enemy. The attractant comprises ladybug sex pheromone, synomone and kairomone; the synomone is aphid-induced plant volatile matters; and the kairomone consists of aphid warning pheromone, aphid body surface extracts and aphid honey dew volatile matters. The ladybug attractant has good attraction effects, good effect repeatability andhigh stability in both laboratory and field experiments, and has broad spectrum for beneficial ladybugs such as coccinella septempunctata, harmonia axyridis, propylaea japonica and the like.

The invention relates to an insect capture lamp, in particular to a household coccinella septempunctata capture lamp. The household coccinella septempunctata capture lamp comprises a shell. A fixing cover is combined with the top end of the shell in a clamped mode, and a lamp holder is combined with one side of the fixing cover in a clamped mode. An LED bulb is arranged inside the fixing cover ina penetrating mode, a clamping block is connected with the interior of the fixing cover in a rotating mode, and a limiting pipe is welded at one end of the clamping block. A first fixing ring is welded at the bottom end of the limiting pipe, sliding channels are welded on the side face of the first fixing ring, and stop plates are arranged in the sliding channels. A turbine drives the stop platesto rotate through a first gear and a second gear. By the adoption of the household coccinella septempunctata capture lamp, the purposes that coccinella septempunctata on a household balcony is captured, and mosquitoes are killed can be achieved, and a good using effect is achieved. In addition, little insects can be killed by the use of the coccinella septempunctata, the food is supplied to the coccinella septempunctata, part of insects with the small size are killed, and the two purposes are achieved through one step.

The invention relates to a primer pair for detecting coccinella septempunctata. The primer pair sequence is shown as SEQ ID No.1 and SEQ ID No.2. The invention also relates to a reagent kit containing the primer pair and a detecting method for detecting coccinella septempunctata by virtue of the primer pair and the reagent kit. The detecting method is simple, fast, peculiar and sensitive.

The invention provides an attractant for coccinella septempunctata. The attractant for the coccinella septempunctata consists of the following raw materials: 280 to 370 grams of triple superphosphate, 50 to 67 grams of diammonium and 21 to 30 grams of plant ash, wherein the ash rate of ramie root to tamarix to diversifolious poplar in the plant ash is 1:1:1. The attractant for the coccinella septempunctata is prepared by the following steps of: crushing the triple superphosphate and the diammonium into powder; mixing the power and the plant ash; and adding 18 to 35 kilograms of water to stir uniformly and spraying the mixture. The attractant for the coccinella septempunctata is sprayed for twice every year and aims to induce the coccinella septempunctata and kill aphids in the cotton field, wherein the first spraying time is from the twelfth day to the fifteenth day in June and germinated fruit branches of cotton is protected from being infringed by the aphids; the second spraying time is from the twenty-eighth day in July to the first day in August and cotton bolls are protected from being infringed by the aphids; and the spraying temperature is between 28 and 30 DEG C. By the attractant, the yield of the cotton can be increased by 60 to 80 kg / mu. When the attractant is sprayed on melon and fruit, vegetable, red date trees, walnut trees, Pyrus sinkiangensis trees and apple trees, the technical effect of inducing the coccinella septempunctata to kill the aphids is achieved.

The invention belongs to the technical field of insect breeding and particularly relates to a device for trapping coccinella septempunctata for oviposition. According to the device for trapping the coccinella septempunctata for oviposition, a pea seedling carrying sufficient megoura japonica is used as a trapping material, by use of the taxis of the coccinella septempunctata to aphids, the coccinella septempunctata and the pea seedling carrying the sufficient megoura japonica are placed in an oviposition container for trapped oviposition, the trapping effect is obvious, the coccinella septempunctata can be trapped together, and gathered oviposition of the coccinella septempunctata is facilitated; a smooth black PE bag which has the high oviposition amount and is 0.1-0.2 mm thick is used asan oviposition carrier, the oviposition rate of the coccinella septempunctata and the recovery rate are effectively increased, the problems that the oviposition amount of the coccinella septempunctata and the recovery rate of eggs are low is solved effectively, and the method plays an important role in guaranteeing population reproduction of the coccinella septempunctata.

The invention belongs to the technical field of insect cultivation, and in particular relates to a device for luring ladybugs to lay eggs. The device for trapping the seven-star ladybug to lay eggs described in the present invention uses the pea seedlings planted with sufficient Prunus pea as the trapping material, utilizes the tropism of the seven-star ladybug to the aphids, and mixes the seven-star ladybug with the sufficient pea prunus Put the pea seedlings of the tail aphid in the spawning container for trapping and laying eggs, which has obvious trapping effect, and can lure the seven-star ladybugs together, which is conducive to their aggregation and laying eggs; and the smooth one with a high number of laying eggs The black PE bag with a thickness of 0.1‑0.2mm is the egg carrier, which effectively improves the egg laying rate and recovery rate of the seven-spot ladybug, and effectively solves the problem of low egg production and egg recovery rate of the seven-spot ladybug. It plays an important role in population reproduction.

The invention discloses a diapause maintaining and cancellation method of Coccinella septempunctata. The method comprises the following steps: transferring Coccinella septempunctata entering diapause state to a condition of 18 DEG C and lighting period of L10:D14 (or dark) for storage; and after storage, transferring the Coccinella septempunctata to a condition of 24 DEG C and lighting period of L16:D8 to recover development. The method has diapause maintaining time of 114-183 days and diapause canceled in 7.52-8.62 days. The method is of great significance for large-scale propagating Coccinella septempunctata, prolonging shelf period and field prevention / control action time, grasping natural enemy insect development characteristic and occurrence dynamics, improving pest prevention / control efficiency, deepening understanding about natural enemy insect development mechanism, and investigating environment adaptability mechanism and evolution route of insect.
