Embodiment 1

[0053] 1) Prepare a blank control: no semiochemicals are added to the lure of the insect trapping device;

[0054] 2) Preparation of lures with semiochemicals: the semiochemicals used are the original drug of linalool (97% active ingredient, Sigma-Aldrich company), directly absorb 100 μL of the stock solution of linalool and add it to the lure, and wait to lure After the semiochemical liquid in the core is completely volatilized, insert it into the environmentally friendly yellow sticky insect board;

[0055] 3) Remove adult Bemisia tabaci (male and female) from cotton or pepper, and starve for 2 hours at room temperature;

[0056] 4) The lure core is built into the central position of the insect trapping device;

[0057] 5) Put the blank control and the insect trapping device with the lure into the bemisia tabaci insect cages equipped with cotton or pepper plants, and record the adults of bemisia tabaci trapped by a single sticky insect yellow plate within 30 minutes and 1 h...

Embodiment 2

[0063] 1) Prepare a blank control: no semiochemicals are added to the lure of the insect trapping device;

[0064] 2) Prepare lures with semiochemicals: the semiochemicals used are linalool stock (active ingredient 97%, Sigma-Aldrich company), draw 10 μL of linalool stock solution, add 90 μL of n-hexane and mix to obtain the concentration 0.1μL / μL of semiochemical, then suck 100μL and add it into the lure. After the semiochemical liquid in the lure is completely volatilized, insert it into the environmental protection yellow sticky insect board;

[0065] 3) Remove adult Bemisia tabaci (male and female) from cotton or pepper, and starve for 2 hours at room temperature;

[0066] 4) The lure core is built into the central position of the insect trapping device;

[0067] 5) Put the blank control and sticky boards with lures into the insect cages of Bemisia tabaci with cotton or pepper plants, and record the adults of Bemisia tabaci trapped by a single yellow sticky board within 3...

Embodiment 3

[0073] 1) Prepare a blank control: no semiochemicals are added to the lure of the insect trapping device;

[0074] 2) Prepare lures with semiochemicals: use the semiochemicals as the original drug of linalool (active ingredient 97%, Sigma-Aldrich), add 10 μL of linalool stock solution, add 990 μL of n-hexane and mix to obtain a concentration of 0.01 μL / μL of semiochemicals, then suck 100 μL and add it into the lure, after the semiochemical liquid in the lure is completely volatilized, insert it into the environmental protection yellow sticky insect board;

[0075] 3) Remove adult Bemisia tabaci (male and female) from cotton or pepper, and starve for 2 hours at room temperature;

[0076] 4) The lure core is built into the central position of the insect trapping device;

[0077] 5) The blank control and the insect trapping device with lure cores are placed in the insect cages of Bemisia tabaci with cotton or pepper plants, and the number of adults of Bemisia tabaci trapped by a...

Abstract

The invention provides an insect trapping device with trapping semiochemicals used for a trapping core and a method. Therefore, no less than 70 insects (preferably bemisia tabaci) can be trapped within one hour n average and no less than 200 insects can be more preferably. The insect trapping device is formed by yellow eco-friendly plate-shaped material such as paper. Eco-friendly insect-sticking glue can be coated on the upper surface of the plate-shaped material. The upper surface of a panel can be embedded with the trapping core with trapping semiochemicals which are linalool. When the insect trapping device is prepared, a yellow insect-sticking plate is firstly prepared and linalool or n-hexane is directly used as solvent and added into the trapping core. After the semiochemical liquid in the trapping core compeletly volatizes, the yellow insect-sticking plate is inserted. The insect-sticking plate is high in trapping efficiency, easy in operation and high in safety and is eco-friendly. The utilization rate of a color plate is reduced and cost is further lowered.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to an insect trapping device and method for trapping pests (preferably Bemisia tabaci) with trapping semiochemical lure cores. Background technique [0002] At present, it is very common to use swatches to trap and kill insects. The purpose is to reduce the use of chemical pesticides. However, due to the low trapping efficiency, a large number of swatches are required in actual use, which not only affects the environment, but also increases the cost of control. At the same time, swatches are also widely used in forecasting work, such as the forecasting and forecasting of population dynamics for some whiteflies, aphids, thrips, etc. However, the population dynamics of target pests cannot be correctly predicted if the trapping effect is low. [0003] In the animal kingdom, except for a few species (such as howler monkeys), the visual and olfactory abilities are always opposite, that i...
