Abstract
the invention discloses a method for quickly separating mosquito pupae. The method comprises the steps of pouring a mixture of mosquito larvae and pupae into ice water, floating the pupae on the water surface, sinking the larvae into the ice water, and respectively fishing out the upper pupae and the lower pupae to obtain separated pupae and larvae. The inventor finds that when larvae and pupae of mosquitoes are placed in ice water, the larvae automatically sink at the moment of being frozen, the pupae float on the water surface, and when the temperature of the ice water is raised to normal temperature (25 ℃) after the pupae is fished out, the larvae automatically float upwards. Therefore, the mosquito larva and pupa separating device can effectively separate the mosquito larvae and pupae, improves the separation efficiency of the mosquito larvae and pupae, saves time and labor, and does not damage the pupae.
Description
Technical Field
the invention belongs to the field of mosquito control, and particularly relates to a method for quickly separating mosquito pupae.
Background art:
The major harm to mosquitoes is the transmission of disease. Mosquito-transmitted diseases have been studied as many as 80. Killing mosquitoes is an effective way to prevent and reduce diseases. In the experiment, a large amount of mosquitoes are needed to carry out researches on attractants, repellent agents, sterility technologies and the like. Therefore, a large amount of mosquito pupae and later adults need to be obtained for experimental verification.
The invention content is as follows:
The invention aims to provide a method for quickly separating mosquito pupae.
The invention discloses a method for quickly separating mosquito pupae, which comprises the following steps:
Pouring the mixture of mosquito larva and pupa into ice water, floating pupa on water surface, depositing larva in ice water, and respectively fishing out upper pupa and lower pupa to obtain separated pupa and larva.
The collected pupae can be used for pupal stage tests or experimental needs of adult culture.
Preferably, said mixture of mosquito larvae and pupae is obtained by: pouring culture medium or culture solution containing mosquito larva and pupa into screen mesh, filtering with water, and removing the medium to obtain mosquito larva and pupa mixture.
The screen is a 20-mesh screen.
Preferably, the culture medium or culture solution containing the larvae and pupae of the mosquito is poured into a screen, filtered with water, the medium or culture solution is removed to obtain a mixture of the larvae and pupae of the mosquito, the mixture of the larvae and pupae of the mosquito is poured into ice water, the pupae floats on the water surface, the larvae sink in the ice water, then the pupae is collected by a filter spoon with a screen, and the larvae on the lower layer are collected to obtain separated pupae and larvae.
the inventor finds that when larvae and pupae of mosquitoes are placed in ice water, the larvae automatically sink at the moment of being frozen, the pupae float on the water surface, and when the temperature of the ice water is raised to normal temperature (25 ℃) after the pupae is fished out, the larvae automatically float upwards.
Therefore, the mosquito larva and pupa separating device can effectively separate the mosquito larvae and pupae, improves the separation efficiency of the mosquito larvae and pupae, saves time and labor, and does not damage the pupae.
description of the drawings:
FIG. 1 is a graph showing the effect of separation of mosquito larvae and pupae.
The specific implementation mode is as follows:
The following examples are further illustrative of the present invention and are not intended to be limiting thereof.
Example 1:
pouring a culture medium containing larvae and pupae of mosquitoes for a raised experiment into a filter cup with a 20-mesh sieve pore on the bottom wall, filtering with water, removing the medium (filtering the medium out of the sieve pore) to obtain a mixture of the larvae and pupae of the mosquitoes, placing the filter cup containing the mixture of the larvae and pupae of the mosquitoes into ice water, enabling the ice water to enter the filter cup through the sieve pore, waiting for 10 seconds, enabling the pupae to float on the water surface, enabling the larvae to sink in the ice water, collecting the pupae with a filter spoon with a screen, lifting the filter cup after collection, and obtaining the larvae at the bottom of the filter cup. The collected pupae are living bodies and can be hatched into imagoes, so that the pupae can be used for pupal stage experiments or adult culture experiments.
Comparison: the mixture of the larvae and pupae of the mosquitoes is poured into water at normal temperature (25 ℃), the larvae and pupae of the mosquitoes float on the water surface, and the larvae of the mosquitoes do not sink into the water or the water bottom.
example 2:
Feeding 200 aedes albopictus pupas and 200 aedes albopictus larvae in a culture solution mixed in a water pan, then pouring the mixture into a filter cup with a 20-mesh sieve pore on the bottom wall, flushing and filtering the filter cup with water, removing the culture solution to obtain a mixture of the larvae and the pupas of the mosquitoes, placing the filter cup containing the mixture of the larvae and the pupas of the mosquitoes into ice water, enabling the ice water to enter the filter cup through the sieve pore, waiting for 10 seconds, enabling the pupas to float on the water surface, enabling the larvae to sink in the ice water, collecting the pupas by using a filter spoon with a screen, lifting the filter cup after collection is finished, and obtaining the larvae at the bottom of the filter cup. The collected pupae are living bodies and can be hatched into imagoes, so that the pupae can be used for pupal stage experiments or adult culture experiments.
The results of the experiment are shown in FIG. 1, and it can be seen from FIG. 1 that the larvae and pupae are well separated.
Example 3:
The mixture of larvae and pupae of aedes albopictus of example 2 was poured into ice water and after waiting 10 seconds, the pupae floated on the water surface while the mosquito larvae settled in the water.
Comparison: the mixture of larvae and pupae of Aedes albopictus was poured into water at room temperature (25 deg.C) to allow both larvae and pupae of mosquito to float on the water surface without sinking into the water.
