Detailed Description
The method for breeding the female mosquito that spawns of aedes albopictus according to the present invention will be described in further detail with reference to the following embodiments.
Example 1
The method for feeding aedes albopictus spawning female mosquitoes provided by the embodiment comprises the following steps:
eclosion: in an adult mosquito rearing room with a temperature of 26-28 ℃ and a relative humidity of 65-85%, mosquito pupae of aedes albopictus, of which the number ratio of female pupae to male pupae of aedes albopictus is shown in table 1, are placed into an adult mosquito rearing cage (specification: 30cm), a box cover of a pupae box in the adult mosquito rearing cage is opened, the mosquito pupae is turned into adult mosquitoes, and a glucose water solution with the mass concentration of 10% is provided for the adult mosquitoes during eclosion (the method is that 10% of cotton soaked by the glucose water solution is placed above the adult mosquito rearing cage to ensure that the cotton contains enough glucose water solution, and the cotton containing the glucose water solution is changed once every other day), and the mosquito pupae are totally eclosion into adult mosquitoes after 2 days. Three parallel sample experiments were performed for each ratio.
Spawning: after 5 days, feeding anticoagulated sheep blood for the first time to the female mosquitoes (the temperature of the sheep blood is maintained at about 37 ℃ so as to be convenient for the female mosquitoes to suck, and the blood feeding time is about 1-2 hours each time), after one day, placing a spawning cup in a adult mosquito feeding cage until the female mosquitoes spawn for the first time; collecting the mosquito eggs in the egg laying cup for the first egg laying after two days, and feeding anticoagulated goat blood for the second time for the female mosquitoes; after the second blood feeding, placing a spawning cup in the adult mosquito rearing cage for the female mosquito to spawn for the second time; two days later, the mosquito eggs in the egg laying cup for the second egg laying were collected, and the number of eggs laid twice was counted as shown in table 1.
Hatching: the mosquito eggs can grow to be mature after being collected for one week, and the mature mosquito eggs are hatched into larvae, and the method comprises the following steps: adding water into yeast peptone to prepare an aqueous solution with the concentration of 0.9g/L, and taking the aqueous solution as hatching fluid; the yeast peptone is Angel yeast peptone FP101, which is a stable, safe and comprehensive nutrient peptone prepared by separating and enriching yeast protein treatment and complex enzyme action of pure cultured high-protein baker's yeast. The contents thereof are as follows, total nitrogen: not less than 10.0%, a-amino nitrogen: not less than 2.5%, water content: less than or equal to 6.0 percent, NaCl: 2.0% or less, ash content: less than or equal to 15.0%, pH (2% solution): 5.3-7.2;
placing the hatching solution at the temperature of 25-30 ℃ for fermenting for 24 hours to obtain fermented hatching solution;
weighing 0.05g of aedes albopictus eggs (1g ═ 15 ten thousand eggs) and adding to a 15mL hatching tube, and adding 10mL of fermented hatching fluid (the fermented hatching fluid accounts for 2/3 of the volume of the hatching tube) to the hatching tube; sealing the tube cover of the incubation tube, shaking up, standing and incubating for 1 hour at the temperature of 25-30 ℃, then opening the tube cover of the incubation tube, and transferring the incubated larvae to a feeding tray. The larval hatchability of the mosquito eggs was counted as shown in table 1. Wherein, the larva hatchability is the ratio of the number of hatched larvae to the total number of hatched mosquito eggs, and the higher the hatchability is, the higher the quality of the mosquito eggs is, and the higher the proportion of active mosquito eggs is. The hatching rate of the active mosquito eggs refers to the ratio of the number of hatched larvae to the total number of the active mosquito eggs used for hatching.
TABLE 1
Figure BDA0001402244340000051
Figure BDA0001402244340000061
As can be seen from the results in table 1: the male and female ratio of the mosquito pupae plays a key role in the breeding rate and the quality of spawning of the female mosquitoes. When the male-female ratio is 2: 1-4: 1, the average egg laying amount of a single female mosquito is 57.15-54.98, the average hatching rate of larvae is 68.58-71.90%, and particularly when the male-female ratio is 3:1, the egg laying amount of the female mosquito is the highest, the mosquito egg quality is high, and the larva hatching rate is high; when the ratio of the male to the female exceeds the range of 1: 1-5: 1, the egg laying amount or the hatching rate of the mosquitoes is greatly reduced, and when the ratio of the male to the female is 1:2, the average egg laying amount of a single female mosquito is 42.32; when the male-female ratio is 6:1, the average egg laying amount of a single female mosquito is 40.13, and the average hatching rate of larvae is 53.43 percent. It can be seen that the preferred range of the hermaphroditic ratio is 2:1 to 4:1, and controlling the hermaphroditic ratio within this range enables both higher egg laying rate and larva hatching rate to be achieved.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
