Embodiment 1

[0031] In the rearing room equipped with a constant temperature air-conditioner, adopt the same number and power of illumination devices to move rice seedlings and striatellus in the same state into the beaker and the co-cultivation box of the present invention respectively. The light intensity in the co-incubation box of the invention is measured by an illuminometer, and the measured light intensity results are shown in Table 1. It can be seen from Table 1 that the average light intensity in the beaker is very low, with an average of only 195 μmol m -2 ·s -1 , the illuminance is about 14295 lux (under the condition of ordinary fluorescent lamp, 1μmol·m -2 ·s -1 ≈73.30Lux), while under the same conditions, the average light intensity under the indoor beaker culture rack is 287.5μmol·m -2 ·s -1 , the illuminance is about 21076lux, and the reason for the loss of light is that the gauze at the mouth of the beaker prevents insects from escaping. Because the light saturation p...

Embodiment 2

[0035] BPH is a temperate insect with strong low temperature tolerance, but poor adaptability to high temperature. The optimum growth temperature is between 23.5-28°C, and the optimum temperature is 25°C. In the range of 15-25°C, the growth rate of eggs and nymphs will accelerate with the increase of temperature. When the daily average temperature exceeds 29°C or reaches an extreme high temperature of 35°C, the growth cycle of nymphs will be prolonged, stunted or even dead. In the rearing room equipped with a constant temperature air conditioner, sow Wuyujing No. 3 respectively in beakers and the co-cultivation box of the present invention, and transfer into 1-2 instar SBPH nymphs after 5 days of sowing, and the beaker, the co-cultivation box of the present invention are treated every day. The temperature in the incubator and the indoor ambient temperature are measured, wherein the indoor temperature fluctuates up and down at 25°C. For studying the environmental characteristics...

Embodiment 3

[0037] In the rearing room where the constant temperature air-conditioning is installed, rice seedlings and SBPH in the same state are moved into the beaker and the co-cultivation box of the present invention respectively, and the indoor environment, the beaker cultivation method and the humidity in the co-cultivation box are measured, and the result It was found that the humidity in the beaker was consistent with the humidity in the constant temperature room environment, and the humidity range in the constant temperature room was 64%-83% within the measurement time. Cultivation of SBPH is easily disturbed by season and climate. And the relative humidity in the co-incubation box of the present invention is found through measurement, the humidity in the device is stable in the scope of 78%-81%, is little affected by the external environment, and can play a larger buffering effect on the external environment; At the same time, because the optimum humidity for the growth of SBPH ...

Abstract

The invention discloses a crop and insect co-cultivation box which comprises a box body (1) and a seedling raising disk (4), wherein, an upper cover (2) is arranged at the top of the box body (1), and a box door (3) is installed at the upper part of a front wall of the box body; a rightwards opened square-shaped lug boss (5) used for holding the seedling raising disk (4) is arranged on the inner wall of the box body (1); the upper edge of the seedling raising disk (4) is positioned on the upper side of the lug boss (5); a lighting device (6) positioned on the lower side of the upper cover (2)is arranged at the upper part of an inner chamber of the box body (1); a blower (7) is arranged at the upper part of a rear wall of the box body (1); a liquor feeding pipe (9) communicated with the inner chamber of the box body (1) is arranged on the outer side of the lower part of the box body (1); and a control switch (8) is arranged on the liquor feeding pipe (9). The crop and insect co-cultivation box provides a crop and insect co-cultivation platform that achieves full automation, good effect, low construction cost and wide application range, and can be widely applied to crop and insect interaction researches such as crop cultivation, insect raising, insect resistance of crop, and identifications on disease resistance of bacteriosis and virus of insect vectors.

Description

technical field [0001] The present invention relates to the fields of agriculture and biological scientific research, in particular to a device for large-scale feeding of crop phytophagous insects and as a platform for identification of insect resistance and insect vector bacterial virus disease resistance of crops, specifically It is said to be a crop insect co-incubator suitable for raising crop insects and cultivating crops simultaneously. Background technique [0002] There are many kinds of herbivorous insects, and the population is huge, which has brought great harm to agricultural production. In addition to directly eating crops, many herbivorous insects can cause the yellow leaves to die, the yield is reduced, and the quality is reduced. , the transmission medium of bacterial disease, only the crop virus disease that insect spreads causes the loss to crop production to reach several billion dollars every year. [0003] There are many kinds of insects that endanger a...
