Description
Technical field
The present invention relates to the technology of mass rearing grained moth in the agro-ecology field.
Background technology
Rice moth (Col ' cyra cephalonica) be a kind of stored grain insects, its ovum can be used as the host of parasite or the feed of predator insect.Therefore, in many years in the past, a large amount of Study on Production Technology of rice moth are subjected to countries in the world biological control worker's great attention all the time.But there are many shortcomings in the method for in the past producing rice moth, makes this technology fail to promote in production reality, and these shortcomings are summarized can be divided into following several respects:
1, feed is mouldy easily.The main component of feed is rice bran or wheat bran, for making the neat and small grub of rice moth egg hatching survive the ratio raising, the water content of feed generally is controlled at more than 15%, past, reinforced mode was fixed, therefore promptly the process of feeding intake is disobeyed the larval feeding amount and is decided, but adds the material of some at every turn, is reaching 40-50 days rice moth in larval phase, be under about 80% the environmental condition in relative temperature, feed very easily is subjected to the pollutions of various assorted bacterium and moldy metamorphism.Not only rice moth larva aphagia of feed after rotten, and the environment after going mouldy can cause the mortality of larva, and lethality can reach 100% sometimes.
2, raising feed in early stage is blocked up, and temperature is difficult for scattering and disappearing.Because the activity of microorganism and larva all can produce a large amount of heat, feed is blocked up and raise in earlier stage, and temperature is difficult for scattering and disappearing, and after 15 days, the feed temperature can be raised to about 40 ℃ sometimes, causes the larva death of 60-80% in the rice moth inoculation.
3, gallery irregularity is grown inconsistent.Method in the past is once inoculation on the bed of material that approximately 5cm is thick, just pierce after the larva hatching and get food in the feed, grow, larva weaves silk, and adhesion becomes certain duct with ight soil with swill, the end opening that head is only arranged, larva is ensconced wherein, if there are not alien enemy's special circumstances such as infringement, whole larval phase and pupa time will be always in the ducts, along with the gallery of growing up of polypide also can constantly extend forward.Because these gallerys are random, be wrapped in the material mutually, only causing, the insect of 20-30% may obtain sufficient feed, and other are because of being crushed on other gallery bottom or by other gallery the food obstruct being opened, and insect will grow slowly or stasi because of can not get sufficient food, and final result is that the emergence time is very irregular, emergence period often reaches more than two months, the polypide size differs greatly, though many insects sprout wings reluctantly, has 50% can not lay eggs.
4, wasting space.Aging method does not reach the high-density rearing, every square metre go out moth amount only about the 1000-2000 head, the rice moth egg of sufficient amount is provided for production, just will take a large amount of spaces and specifically be reflected in use a large amount of foster worm frame and insectary.
5, other stored grain insects of easy infection.Though the feed that aging method uses is through baking disinfecting, still can not avoid the infringement of other stored grain insects, inoculating rice moth egg after 20-30 days often, other stored grain insects, as intend that ostomatid etc. is a large amount of takes place, a large amount of on the one hand feeds that consume of these insects discharge the environment of some noxious materials around poisoning on the one hand, rice moth can't be survived, can cause the rice moth 80%-90% underproduction or not have output at all.
6, collect difficulty.After the rice pretty young woman sprouts wings, moth is dispersed everywhere, general employing adds the yarn lid and collects or collect with the receipts moth device of dust catcher repacking, efficient is all very low, and the moth bulk diffusion is serious, can only collect for each person every day between 20 square metres feeding room, and because dust from flying, cause great damage for operator's health, and the receipts moth is not thorough, the moth that is hidden in edge is difficult to be collected into.
