Embodiment 1

[0054] In the artificial feed preparation process of the standardized feeding and management method of Chilo suppressalis, according to the different ages of larvae and the difference in the number of inoculated insects in a single bottle, three types of feed dosage specifications are divided, including small amount of feed, large amount of feed and medium amount of feed. Packed in wide-mouth glass jars as feed bottles. Among them, the amount of small amount of feed is about 40ml, which is used to inoculate the 1st to 2nd instar newly hatched larvae, and the amount of inoculated worms in a single bottle is 800 to 1200 heads / bottle. The amount of large-scale feed is about 120ml, which is used to inoculate 3rd to 4th instar larvae, and the amount of inoculated larvae in a single bottle is 150-200. The amount of medium feed is about 60ml, which is used to inoculate the 4th to 5th instar newly hatched larvae, and the amount of inoculated larvae in a single bottle is about 50.

Embodiment 2

[0066] In the standardized feeding and management method of Chilo suppressalis, according to the 36-day feeding process of larvae, the timeline of the single-batch feeding operation process and the amount of feed are shown in Table 1.

[0067] Table 1. Time axis and feed consumption of single batch feeding operation process

[0068]

[0069] Note: (1) A single batch number A-30 indicates a new batch on the 30th day of month A. (2) In conventional feeding operations, 0 means to collect 5-day-old egg masses and create a new batch; 1 means egg mass collection and inoculation; 2 means take out dishes; 3 means divide bottles; 4 means take old feed; 5 means second replacement; 6 means One pupa: 7 means two pupae: 8 means three pupae: 9 means four pupae. (3) In the amount of feed, S represents a small amount of feed, M represents a medium amount of feed, and L represents a large amount of feed.

[0070] The following combines Table 1 and figure 1 The 36-day rearing process of l...

Embodiment 3

[0086] The adult feeding process of the standardized feeding and management method of Chilo suppressalis is carried out according to the following steps:

[0087] (1) Take an adult insect cage (L 40cm×W 40cm×H 60), and place it on the multi-layer light insect rearing rack in the adult insect culture room. Get a 300ml disposable plastic bowl, add 1.2~2g cotton and 30~45ml of 10% sucrose water as a sugar water bowl, and place the sugar water bowl in the center of the insect cage for nutrition supplementation for adults.

[0088] (2) Take 4 to 5 cups of brand-new egg-laying seedlings and 2 to 3 pupa collection boxes (containing about 400 to 600 pupae) from larva rearing, put them in insect cages, and evenly disperse them around the sugar water bowl.

[0089](3) Usually, the adult eclosion peak of the box pupae is the 3rd to 5th day after the pupae collection box is moved into the adult insect culture room. After a large number of adults emerge and mate and lay eggs, the egg-layi...

Abstract

The invention discloses a standardized feeding and management method for Chilo suppressalis, which comprises artificial feed preparation, 36-day feeding of larvae and feeding processes of adults. The present invention proposes for the first time that 5 days are used as the cycle for collecting worm eggs for indoor populations, 4 days is used as the cycle for collecting pupae, and 36 days are used as the larva rearing cycle for a single batch of egg masses to be inoculated to the pupation stage. Through the standardized management of the operation process of different insect states, a new management system of multi-batch and overlapping cycle feeding has been established. The invention can not only meet the basic needs of long-term subculture of indoor populations, but also can expand and reproduce at any time according to the change of the number of test insects, which greatly shortens the preparation period of test insects of different ages and different states. In addition, the present invention effectively solves the problem of unstable breeding scale of the indoor population of the stem borer, that is, the sporadic population size shrinks rapidly or even tends to become extinct, and can be popularized as a technical specification for the indoor artificial breeding of the stem borer.

Description

technical field [0001] The invention belongs to the technical field of standardized feeding of insects, and in particular relates to a method for standardized feeding and management of Chilo suppressalis. Background technique [0002] Chilo suppressalis is an important food crop pest, not only widely distributed in the rice producing areas of my country, Southeast Asia, and South Asian countries, but also the dominant species of borer in most rice areas. The insect has the characteristics of borer damage, and it is difficult to achieve the desired effect with conventional control methods. In recent years, with the adjustment of the farming system and planting structure in my country's rice fields and the irrational use of chemical pesticides, the resistance level of Chilo borer has been increasing, and the number of occurrences has shown an obvious upward trend. These unfavorable factors have prompted people to seek more environmental compatibility. Good pest control. At pr...
