Description

Method for breeding Nanmei tomato leaf miner with single head
Technical Field
The invention belongs to the field of insect breeding, and particularly relates to a method for breeding Nanmei tomato leaf miner in a single-head mode.
Background
The southern American tomato leaf miner Tuta absoluta (Meyrinck), which is also known as tomato leaf miner, tomato leaf miner and tomato wheat moth, is preferably used under the common name of the tomato leaf miner and the international common name of the South American tomato leaf moth, belongs to Lepidoptera (Lepidotera) Merlatheridae (Gelechidae), is a Peruvian native to the western South America, is a worldwide quarantine invasive pest, mainly harms tomatoes (including processed tomatoes, fresh tomatoes, cherry tomatoes/cherry tomatoes and the like), eggplants, potatoes, physalis alkekengi, ginseng fruits, tobaccos and the like, is rapidly diffused, has the extremely high yield reduction rate of 50-80% in severe occurrence, and even damages seeds for rebroading. At present, although the south American tomato leaf miner only occurs in local areas of China, serious harm is caused to tomatoes in protected areas and open areas, and in order to research a method for controlling the south American tomato leaf miner, the problem that tomato crops are seriously damaged is effectively solved, and the problem of feeding the south American tomato leaf miner must be solved.
Because the problem that the abnormal death rate of insects is high when insects are fed by leaves separated from plants is solved, the method for feeding the south American tomato leaf miner in the prior art mainly adopts a potted host cage for feeding, and mainly comprises the following methods:
1) the single-head feeding method of the insect cage for the miniature blade comprises the following steps: the feed is mainly used for feeding small insects such as aphids, whiteflies and the like; the host plant is a potted plant or a plant directly planted in the field. The culture utensil consists of spun yarn, organic glass tube, buffering sponge, powerful glue, metal clip, etc. When feeding, the culture vessel is directly clamped on the leaf connected with the insect by a metal clamp. 2) The method for feeding the miniature blades with the spun yarn bags at one end comprises the following steps: the host plant is a potted plant or a plant directly planted in the field. The culture vessel is a spun yarn bag, which is composed of spun yarn and tightening rope, and is sewed by sewing machine, and the length, width and thickness are 12-15cm, 8-10cm and 2.5-3cm respectively. When feeding, the spun yarn bag is directly tied on the blade. 3) The transparent happy box single-head breeding method comprises the following steps: the host plant is a hydroponic plant. The culture vessel consists of two round transparent hasp boxes (the diameter and the height are respectively 10cm and 15+15cm), a plastic foam plate, tap water, a sealing adhesive tape, a spun yarn covered air vent and the like.
However, the first and second methods have the following drawbacks: 1. because the weight of the culture vessel is attached to a single leaf, the leaf is often broken and falls off in advance, and the leaf is dried up when the insect does not grow completely; 2. because the culture vessel can not rotate freely after being fixed, only a certain angle of the leaf can be observed, which is not beneficial to observation, especially the observation of the ovum and the primary ovum larva; when observed through a culture vessel containing spun yarns or spun yarn bags, the visual field is fuzzy, and the observation effect on leaf miner pests (such as leaf miners, leaf miners and the like) is poor; 3. because the space is small and the area of the leaves is limited, the larvae can leave the cage area through the sneak food submerged channel, so that single-end feeding and observation cannot be continued, and the experiment is forced to be terminated; 4. the potted plant occupies a large space, can only be carried out in fields, greenhouses or small-sized artificial climate chambers, the environmental conditions in the fields and the greenhouses are difficult to control, the small-sized artificial climate chambers can control the temperature and the humidity, but the feeding scale is very limited, for example, at most 4 potted plants can be placed in one small-sized artificial climate chamber with the volume of 450L, and one plant can only be used for feeding and observing about 40 insects at the same time according to 10 true leaves.
The third method has the defects that the culture vessel cannot be laterally arranged and observed in an inverted mode (the lateral arrangement and the inverted mode can cause the water culture to spill), so that the insect age and the insect state are not clearly distinguished, and the observation result is not accurate, particularly the observation result of the submerged insects, eggs (about 0.3mm) and newly hatched larvae (about 0.5mm in body length) is not accurate; the scale of the method is difficult to expand, for example, a small artificial climate chamber with the volume of 450L can only observe and raise 40-50 insects at most simultaneously.
