Problems solved by technology

However, the actual application effect of the new medicament is not ideal, and there is a big gap with Mirex, which is mainly reflected in two aspects. First, the new medicament is difficult to achieve the effect of eliminating the entire nest of termites, and can only reduce or inhibit the number of termite colonies. Reduce its harm; Second, new agents need to be repeatedly sprayed to achieve the above effects

Embodiment 1

[0020] A high-voltage buried cable needs termite control. Through the indoor toxic effect test, determine the toxic effect of the spinosad bait to the milk termites of Taiwan, the result shows: the content of the spinosad to the half lethal time LT50=5 days of the milk termites of the Taiwan milk termites is 0.002%, LT50= The content in 1 day is 0.005%. According to the above data, three kinds of bait with the content of 0.002%, 0.003% and 0.004% of spinosad are prepared respectively. The bait used in the bait is about 300mm long and 40mm× 400mm pine beams, on the open space within 30m around the cable trench, bury a piece of bait with different contents in the order of content at intervals of 3m. After 3 years of continuous monitoring after spraying, there was no sign of termite activity around the cable trench, which ensured the safe operation of the cable.

Embodiment 2

[0022] A residential area requires termite monitoring and control. Through the indoor toxicity test, the toxic effect of fipronil bait to Coptotermes formosanus or Coptotermes formosanus was determined. The results showed that the content of fipronil to Coptotermes formosanus was 0.0005% when LT50=5 days, and LT50=1 The content of days is 0.001%; ​​the content of fipronil is 0.0003% when LT50=5 days to the median lethal time of termites, and the content is 0.0008% when LT50=1 day. According to the above data, the content of the prepared fipronil is respectively 0.0003 %, 0.0005%, 0.0007%, and 0.0009%. The bait used for the bait is a pine strip with a length of about 200mm and a size of 10mm×10mm. In the pre-fabricated termite monitoring holes underground around the building, every 9m 2 One termite monitoring hole is set up in the area. After spraying once, the termite damage rate of residents in the community dropped from 9.5% before spraying to 0% one year later, and the te...

Embodiment 3

[0024] A reservoir dam needs termite control. Through the indoor toxicity test, the toxic effect of sulfluramid bait on the black-winged termite or the yellow-winged termite is determined, and the results show that the content of sulfluramid to the half-lethal time LT50 of the black-winged termite is 0.05% at 5 days , the content during LT50=1 day is 0.15%,; the content of sulfluramid is 0.05% when LT50=5 days to the median lethal time of the yellow-winged giant termite, and the content during LT50=1 day is 0.1%, according to the above data, the preparation of fluoride The content of insectamine is 0.05%, 0.07%, 0.10% and 0.15% respectively in four kinds of baits. The bait used in the bait is eucalyptus bark with a length of about 250mm and a width of about 50mm. A piece of bait with different contents is buried in the order of high and low. Check the feeding rate of the bait and the signs of termite activity such as mud line and other termite activities every month within on...

Abstract

The invention discloses an application method of multi-content combined baits for controlling termites. The method is characterized by firstly measuring the content of one pesticide when the median lethal time LT50 of the pesticide on one type of termites is 5 days and taking the content as a minimum value of the combined bait, measuring the content of the pesticide when the median lethal time LT50 of the pesticide on the type of termites is 1 day and taking the content as a maximum value of the combined bait, then selecting a plurality of values between the minimum value and the maximum valueaccording to the gradient and preparing baits with different contents. When the multi-content combined baits are applied, the baits with different contents are combined together and are applied to the same point or the baits with different contents are applied every one point, so that the bait with relatively high content is degraded to an optimal level when the effect of the bait with optimal content is reduced due to degradation, thus ensuring that one part of the baits are in best state of the effect all the time in a fairly long time after applying the combined baits for one time; the purposes of improving the effect of controlling the termites, reducing repeated bait application and improving the operating efficiency can be achieved; the method is green, environmentally friendly, economical and efficient.

Description

Technical field: [0001] The invention belongs to the field of termite control, and in particular relates to a multi-content combined bait application method for termite control. Background technique: [0002] Termites belong to the insects of the order Isoptera, and were once listed as one of the world's five major pests by the International Center for Insect Physiology and Ecology (ICTPE). Power and communication equipment and other hazards are serious. Because the activity of termites is very hidden, it is difficult to find their nests for prevention and control. The main control method is trapping and killing, that is, after some worker ants foraging outside the termite nests take the bait, they bring the medicine back to the nest and feed each other so that the whole nest of termites dies. , So far, booby trapping is considered to be the most effective way to control termites. [0003] However, in the past few decades, the active ingredient of domestic baits used to tr...
