Method for adjusting proportion of male and female prepupae of hermetia illucens by using feed

A black soldier fly and pre-pupae technology, which is applied in the field of black soldier fly breeding, can solve the problems of low total egg production, high egg production cost, and the inability to accurately control the proportion of black soldier fly adults, so as to reduce production costs and improve Fecundity and the effect of reducing the number of male worms

Problems solved by technology

[0004] At present, the ratio of male and female pupae of black soldier flies commonly used in breeding black soldier flies is 0.9 to 1.1. Under the normal state of the whole breeding process, the male black soldier flies will pre-pupa one to two days earlier than the male and female flies. However, there is currently no separation of black soldier flies. In the method of male and female pupae, black soldier fly males will emerge 2-3 days earlier than females, so the proportion of black soldier fly adults in the breeding room cannot be accurately controlled, and sex ratio imbalance is prone to occur. Adults do not mate in time or do not mate after eclosion. The total egg production is low, and the production cost of eggs is high

Embodiment 1

[0028] The present embodiment provides a kind of method utilizing feed to regulate the ratio of black soldier fly male and female prepupa, comprising the following steps:

[0029] (1) The newly hatched larvae are placed in the feeding box, and after feeding feed for 25 days, the amount of feeding feed in the first 5 days is 2 kg altogether, and the amount of feeding feed in the 6th to 25th day is 8 (kg / m 2 ) / d, stop feeding for 2 days, and collect the male prepupa that crawls out of the first stage simultaneously, the quality of male prepupa accounts for 5% of total prepupa quality, after weighing, mark the date and place it in the pupation chamber;

[0030] (2) After continuing to feed the remaining prepupa of step (1) for 2 days, the amount of feeding feed is 1 (kg / m 2 ) / d, stop feeding for 2 days, and collect the male prepupa that climbed out in the second stage simultaneously, the quality of male prepupa accounts for 20% of the total prepupa quality, after weighing, mark t...

Embodiment 2

[0036] The present embodiment provides a kind of method utilizing feed to regulate the ratio of black soldier fly male and female prepupa, comprising the following steps:

[0037] (1) The newly hatched larvae are placed in the breeding box, and after feeding feed for 21 days, the amount of feeding feed in the first 5 days is 2 kg altogether, and the amount of feeding feed in the 6th to 25th day is 12 (kg / m 2 ) / d, the amount of feed is 10kg / m 2 , stop feeding for 2 days, and collect the male prepupa that crawls out of the first stage simultaneously, the quality of male prepupa accounts for 5% of total prepupa quality, after weighing, mark the date and place it in the pupation chamber;

[0038] (2) After continuing to feed the remaining prepupa of step (1) for 2 days, the amount of feeding feed is 3 (kg / m 2 ) / d, stop feeding for 2 days, and collect the male prepupa climbed out of the second stage simultaneously, the quality of male prepupa accounts for 10% of the total prepupa qu...

Abstract

The invention discloses a method for adjusting the proportion of male and female prepupae of hermetia illucens by using feed, and belongs to the field of hermetia illucens breeding. The method comprises the steps that after the components of hermetia illucens feed are adjusted and a population with a high female proportion or a population with a high male proportion is bred, the female and male prepupae of the hermetia illucens are separated in combination with a feeding deprivation means, the hermetia illucens enter an adult breeding chamber according to the proper sex ratio of the adult hermetia illucens, so that the adult hermetia illucens in the adult breeding chamber always maintain a better sex ratio, the adult copulates timely after eclosion, male insects copulate for many times, so that the breeding amount of the male insects is reduced, the reproductive capacity of the adult insects is improved, and the egg production cost is reduced.

Description

technical field [0001] The invention relates to a method for adjusting the ratio of male and female prepupa of black soldier flies with feed, and belongs to the field of black soldier fly breeding. Background technique [0002] Black soldier fly (Hermetis illucens L.) has been widely studied and artificially bred because of its strong ability to transform organic waste into high-quality feed materials. The poor fecundity of adults is one of the main reasons restricting the industrialization of black soldier flies. Therefore, how to improve the fecundity of black soldier flies and reduce the production cost of black soldier flies is a key research direction in the field of black soldier fly breeding. [0003] Studies have shown that male black soldier flies generally emerge 1-2 days earlier than females, and the body length of males is 1-2cm shorter than that of females. The male and female mate within 2-3 days after emergence, and start to give birth 2-3 days after mating. ...
