Female male drosophila separator
Technical field
The invention belongs to Bioexperiment equipment technical field, particularly the female male drosophila separator of one.
Background technology
Fruit bat is a kind of conventional Bioexperiment material.Fruit bat needs after maturation to carry out male and female separation in blake bottle.Male drosophila individuality is less and have copulatory organ, abdomen end black, and the abdomen back of the body has 3 stripe.Female fruit bat individuality is comparatively large and have ovipositor, and abdomen end look shallow, and the belly back side is 5 blackstreaks.General naked eyes examine just can tell male and female, and its male and female are separated by magnifying glass observation after generally being anaesthetized by fruit bat with ether by laboratory.
Larger to fruit bat injury by the mode of etherization.On August 13rd, 2014 application number be 201420155813.3 innovation and creation disclose a kind of fruit bat separator, comprise the storage fly tank being provided with band stopple, storage fly pot bottom is connected with some separator tubes by pipeline, each separator tube is separated tubule by some joints and forms, arrange between adjacent separation tubule and intercept cushion hole, intercept in cushion hole and be provided with dismountable obstruct pin.Although these innovation and creation can avoid the use of ether, its complex operation, and also separating effect is poor, and fruit bat is usually trapped in and is separated in tubule, and experimenter has no way out to it.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of female male drosophila separator is provided, is not using under narcotic prerequisite, realizing the quick separating of female male drosophila.
To achieve these goals, technical scheme of the present invention is as follows: a kind of female male drosophila separator, the arm comprising supervisor and be communicated with supervisor, the both sides of supervisor are provided with the current switch portion of restriction fruit bat, arm are also provided with the switch portion that restriction fruit bat is current; Supervisor offers a gap, be provided with a spacer in supervisor, spacer can horizontally rotate in supervisor, and spacer has a shank, and shank stretches out outside gap.
In this programme, one end of supervisor is used for the fruit bat that cultured, male and female load in mixture to derive from blake bottle, and the other end of supervisor connects the blake bottle of dress male drosophila or female fruit bat separately, and arm fills separately the blake bottle of female fruit bat or male drosophila for connecting.Gap on supervisor, due to the air communication with outside, can induce fruit bat to fly towards gap.Because spacer can horizontally rotate in supervisor, the hand-held shank of experimenter, can promote fruit bat with spacer and fly forward.On the other hand, when flying into the different fruit bat of 2 sexes in being responsible for quickly, 2 fruit bats can be kept apart by spacer, guarantee that they enter different blake bottles separately.Gap makes fruit bat can not stay in being responsible for coordinating of spacer, and female male drosophila can enter respective blake bottle rapidly.Supervisor is generally circle, and have amplification to fruit bat, assistant experiment personnel distinguish its male and female.
As improvement, described switch portion comprises stator and activity template, and one end of activity template is exposed to the outer surface of supervisor and arm, and the other end of activity template is positioned at the inside of supervisor and arm and offsets with stator under the action of the spring.
The switch portion of this programme can regulate the size of opening easily, can put fruit bat into supervisor singly.In addition, activity template rebounds under the action of the spring when offseting with stator and can occur shake and sound, and orders about fruit bat flight forward.
As improvement, described spacer is the convex lens of a circle.Convex lens can amplify fruit bat, and spacer can horizontally rotate and can move along gap, makes experimenter can observe the feature of fruit bat with multi-angle, sees rapidly its male and female clearly.
As improvement, described arm is positioned at the pipeline section at place, gap in the junction with supervisor.Now, by horizontal for spacer in the front of supervisor with arm junction, can stop that fruit bat continues, along supervisor's flight forward, fruit bat to be flown along arm.If make fruit bat continue to fly along supervisor forward, then with spacer, supervisor and the junction of arm are blocked.
As improvement, two ends of described supervisor are provided with the connector for being connected with blake bottle, and the end of arm 2 is also provided with the connector 6 for being connected with blake bottle 7.Connector facilitates and realizes between blake bottle being connected.
In sum, the present invention has the advantage of modern design, practical function, successful, can realize being separated of female fruit bat and fanout free region between male drosophila efficiently.

Embodiment
Embodiment 1
As shown in Figure 1, a kind of female male drosophila separator, the arm 2 comprising supervisor 1 and be communicated with supervisor 2, supervisor 1 and arm 2 are transparent glass round tube, two ends of supervisor 1 are provided with the connector 6 for being connected with blake bottle 7, and the end of arm 2 is also provided with the connector 6 for being connected with blake bottle 7.The both sides of supervisor 1 are provided with the current switch portion 3 of restriction fruit bat, arm 2 are also provided with the switch portion 3 that restriction fruit bat is current.
As shown in Figure 2, switch portion 3 comprises stator 31 and activity template 32, and one end of activity template 32 is exposed to the outer surface of supervisor 1 and arm 2, and the other end of activity template 32 is positioned at the inside of supervisor 1 and arm 2 and offsets with stator 31 under the effect of spring 33.
Supervisor 1 offers a gap 4, and be provided with a spacer 5 in supervisor 1, spacer 5 is the convex lens of a circle.As shown in Figure 3, the internal diameter that the radius of spacer 5 is slightly smaller than supervisor 1 makes spacer 5 can horizontally rotate in supervisor 1, and spacer 5 has a shank 51, and shank 51 stretches out outside gap 4.
Arm 2 is positioned at the pipeline section at place, gap 4 in the junction with supervisor 1.
