Embodiment 1
[0048] A kind of method of indoor raising sugarcane bar borer or two point borer, comprises the following steps:
[0049] S1. Disinfection of egg masses: cut off the egg masses of blackheads, wash them in distilled water, and then put them in disinfectant water (including 2% sodium hypochlorite and 2% formaldehyde) for 5 minutes, take them out and put them in distilled water for cleaning. Blot the water on the egg mass with sterile filter paper, and place it on the aseptic operating table for later use.
[0050] S2. Larva rearing: Adopt the 2-10-20-25 mode: put the egg masses of blackheads into the petri dish and take out the egg shells and filter paper on the second day; increase the worm feed in the petri dish on the tenth day; change a single tube on the 20th day And new big worm feed; Add folded filter paper for pupation on the 25th day.
[0051] The specific operation is as follows:
[0052] Take the prepared worm feed out of the refrigerator and place it for more than ...
Embodiment 2
[0067] S1. Disinfection of egg masses: Cut off the egg masses of blackheads, wash them in distilled water, put them in disinfected water for 5 minutes, take them out and put them in distilled water for cleaning. Standby on the sterile operating table.
[0068] S2. Larva rearing: adopt the 3-12-22-25 mode: that is, put the blackhead egg mass into the petri dish and take out the egg shell and filter paper on the third day; increase the worm feed in the petri dish on the 12th day; change the order on the 22nd day tube and new worm feed; add folded filter paper for pupation on the 25th day.
[0069] The worm feed is made of raw materials according to the following proportions:
[0070] Agar powder 15.0g, fresh sweet corn kernels 250.0g, sugarcane stem powder 40.0g, casein 15.0g, whole egg powder 15.0g, yeast powder 20.0g, sucrose 10.0g, cholesterol 0.3g, sodium chloride 0.2g, ascorbic acid 2.0 g, methylparaben 1.5g, sorbic acid 2.0g, multi-dimensional element tablet 1.0g, 40% v / ...
experiment example
[0080] 1.1 Insect sources:
[0081] The mature larvae of overwintering generations of sugarcane stem borer and two-spotted stem borer were collected from the seriously damaged sugarcane area in Chongzuo City, Guangxi Zhuang Autonomous Region, and brought back indoors for rearing. The larvae were reared with corn cobs in insect cages. After pupation, they emerged in insect cages and mate freely. They laid eggs on sugarcane leaves. After the egg masses hatched into larvae, they were reared circularly, and they were reared for 2 generations for later use.
[0082] Instrument: RXZ-280B intelligent artificial climate box, the set temperature is (26±1)°C, the humidity is (75±5)%, the photoperiod is 16L:8D, the light intensity is 9000lx, manufactured by Ningbo Jiangnan Instrument Factory.
