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 large egg masses and create a new batch; 1 means to collect and inoculate egg masses; 2 means to take out dishes; 3 means to separate bottles; 4 means to take old feed; 5 means to change twice; 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.

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. Take a 300ml disposable plastic bowl, add 1.2-2g cotton and 30-45ml 10% sucrose water as a sugar water bowl, and place the sugar water bowl in the center of the insect cage for nutritional 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 striped rice borer standardized feeding and management method which includes the processes of artificial feed preparation, larva 36-day feeding and adult feeding. The methodfirst suggests 5 days as the period of indoor population egg collection, 4 days as the period of pupa collection and 36 days as the larva feeding period of inoculating single-batch egg masses into a pupation stage. By standardized management of different stage operation processes, a multi-batch overlap loop feeding novel management system is established. The basic requirements of indoor populationlong-term subculture feeding can be met, reproduction can be expanded at any time according to change of test insect dosage, and the preparation period of test insects with different instars and at different stages is greatly shortened. Besides, the method effectively solves the problem of unstable striped rice borer indoor population feeding scale, namely the condition that accidental populationscale rapidly shrinks and even tends to be extinct. The method can be popularized as a striped rice borer indoor artificial feeding technical specification.

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...
