Description

Pipe and using method are raised in a kind of monitoring for tea lesser leafhopper

Technical field

The invention belongs to the biological prevention field of insect, particularly a kind of insect indoor feeding method.

Background technology

Tea lesser leafhopper belongs to Semiptera Auchenorrhyncha cicadelloidea, is one of China topmost insect in tea place.The nymph of this class pest and adult all inhale the juice at the positions such as the tender stem of tea tree and blade vein with the sucking mouth parts thorn, cause the tea tree disorder, and the tealeaves food value of leaf becomes fragile, and has a strong impact on the quality of tealeaves; Female worm originates in ovum in tender stem phloem, hinders the growth of tea tree.In Fujian, every year five, June and nine, October are the smaller green leaf hopper occurrence in peak period, as without prophylactico-therapeutic measures, can cause the tender tip in tea tree top all withered.

The smaller green leaf hopper ovum is about as 0.7mm, becomes polypide long between 2 to 3mm, individual small, and rapidly mobile after smaller green leaf hopper grew into for three ages, and has the ability of spring.Therefore the smaller green leaf hopper body wall is thin, applies a little external force and just can cause its death, catches complete live body from field and observes and acquire a certain degree of difficulty.At present, the multiplex in vitro tea tree tea branch of indoor feeding smaller green leaf hopper or tea shoot are raised.As taken back indoor insertion water containing the tea branch of the tender tip from the tea place clip, smaller green leaf hopper is put on the tea branch and takes food for it; Or worm is put into to the dactylethrae that fresh tea shoot or leaflet tablet are housed and raised.The former is large to the consumption of tea branch, and the nutrition that the tea branch that maintains of water provides is limited, causes the smaller green leaf hopper raised out less than normal; The latter needs tea shoot or leaflet tablet in frequent replacing dactylethrae and pipe, and workload is large, and in Renewal process, smaller green leaf hopper easily escapes or death.

Summary of the invention

The invention provides a kind of monitoring for smaller green leaf hopper and raise pipe and using method, its purpose is: offer the better nutrition of tea lesser leafhopper, reduce the workload while raising, more truly observe more easily that tea lesser leafhopper grows and behavioural habits, and can make its survival rate greatly improve, the scope of activities of restriction smaller green leaf hopper is conducive to the long-term surviving of potted plant tea tree and and continues to provide tea shoot.

For achieving the above object, technical scheme of the present invention is as follows:

Pipe is raised in a kind of monitoring for tea lesser leafhopper, it is characterized in that: the transparent circular glass pipe that tube body is one section both ends open, and glass pipe range 7 cm, diameter 1.5cm, top is as ventilating opening, and with 100 order gauze sealings, bottom does not deal with.

A kind of using method of raising pipe for the tea lesser leafhopper monitoring, it is characterized in that: tea lesser leafhopper that will be to be raised is introduced monitoring and is raised in pipe, then be placed in rapidly on the tea shoot of potted plant tea tree, monitoring is raised the pipe bottom with the dried cotton jam-pack and is fixed on the hard branch of tea shoot pommel.

Wherein, kinds fast, that the bud number is many that described tea tree is chosen more than 2 years, tea shoot grows are carried out potted plant, by good time fertilising and pruning, make the tea tree Fast Growth; When potted plant tea tree starts to sprout in a large number, when reaching 1.5-3cm, tea shoot gets final product.

The smaller green leaf hopper of raising by this method can be the nymph in each length of time, can be also female male imago, and the worm amount that general every cage is put into is no more than five.

In pipe is raised in monitoring, tea shoot comes into leaves to occupy and raises the too many space of pipe or tea shoot and be injured when serious, the tea branch is slowly extracted out in glass tube, allows the smaller green leaf hopper taken food on bud leave if having time tea shoot, then chooses another healthy tea shoot, continues raising.

The invention has the advantages that:

(1) monitoring raising tube body used is circular transparent glass tube, can carry out comprehensive observation, very convenient;

(2) adopt live plant to raise, when being convenient to observe, also guaranteed better the smaller green leaf hopper required nutrition of growing;

(3) tea shoot in the pipe can survive for a long time and grow, and has saved the workload of frequent replacing food;

(4) owing to being to raise in pipe, limit the damaging range of smaller green leaf hopper, alleviated the extent of injury of potted plant tea tree.
