Embodiment 1

[0039] Effects of different time periods and different lengths of Achyranthes bidentata branches on hydroponics

[0040] During the vigorous growth period of Achyranthes bidentata (May to September), choose 7:00~9:00 (20~25℃), 11:00~13:00 (35~40℃) and 17:00~19:00 (25℃). ~30°C), pick 10 branches and leaves of Achyranthes bidentata plants with 5cm stems + 2 leaves, 10cm stems + 4 leaves, 15cm stems + 6 leaves and 20cm stems + 8 leaves, respectively, and keep them moist with water After 24 hours, graded and evaluated according to the freshness of the stems and leaves. Among them, the grading standard of preservation is as follows: the degree of freshness preservation is the highest if the leaves and stems are normal, the degree of freshness preservation is the second when less than half of the leaves are wilted, and the degree of freshness preservation is the lowest if the leaves and stems are wilted.

[0041] Table 1 Comparison of the freshness of Achyranthes knuckles in differ...

Embodiment 2

[0050] Effect of disinfection treatment on Achyranthes knuckle branches

[0051] Immerse the pruned Achyranthes bidentata stem ends in 50% carbendazim 100 times, 500 times, 1000 times and 2000 times respectively for 5s, 10s, 20s and 40s for wound disinfection, and then immerse the sterilized branch ends about 5cm into In ordinary tap water, after 24 hours, check whether there are flocs around the wound surface and whether the water is turbid.

[0053]

[0054] Note: Different uppercase letters indicate significant differences among different treatment times under the same chemical treatment; different lowercase letters indicate significant differences among different agents under the same treatment time.

[0055] It can be seen from Table 2 that different carbendazim concentrations and treatment time have a great influence on the infe...

Embodiment 3

[0057] Different hydroponic solutions were selected for pre-experiment to verify their effects on Achyranthes bidentata hydroponics.

[0058] The selected hydroponic solutions are: distilled water, IBA (0.2mg / L), NAA (0.05mg / L), compound (NAA (0.05mg / L) and root powder (1.0mg / L) in a volume of 1:1 mixed), tap water ("Hygienic Standard for Drinking Water": GB5749-2006) and root powder (1.0mg / L).

[0059] The above-mentioned hydroponic liquids were respectively selected to perform hydroponics on the isolated stems of Achyranthes bidentata, and the rooting conditions were recorded daily, and the rooting rate, root number and total root length were counted.

Abstract

The invention relates to the technical field of indoor insect breeding, in particular to an indoor mealybug and Aenasius bambawalei Hayat breeding method. The method has the advantages that water-cultured achyranthes bidentata is used to breed phenacoccus solenopsis tinsley and the Aenasius bambawalei Hayat, the developmental duration of the phenacoccus solenopsis tinsley and the Aenasius bambawalei Hayat can be shortened effectively, the survival rate and egg number per female of the phenacoccus solenopsis tinsley are increased, the parasitism rate and eclosion rate of the Aenasius bambawaleiHayat to the phenacoccus solenopsis tinsley are increased, and the method is especially applicable to the indoor breeding and researches of the mealybugs and the parasitic natural enemy of the mealybugs.

Description

technical field [0001] The invention relates to the technical field of indoor breeding of insects, in particular to an indoor breeding method of mealybugs and Leucopteris bancrofti. Background technique [0002] Phenacoccus solenopsis Tinsley belongs to the family Pseudococcidae of the order Hemiptera, and it is a serious threat to the safety of economic crops such as field crops, garden ornamental plants, fruit trees and vegetables that has emerged in my country in recent years. Invasive pests, more than 200 species of plants in 55 families in 24 countries around the world are harmed by the pests. At present, the pest has occurred in 13 provinces (municipalities) in my country. Aenasius bambawalei Hayat, belonging to the Hymenoptera (Hymenoptera) Eucyrtidae, is an obligate parasitoid of the dominant species of Fuso mealybug, with a parasitic rate of 50% to 62% in the wild. It has a good application prospect of biological control. Under laboratory conditions, the multiplic...
