The invention relates to culex and aedes attractant and an application method, belonging to the mosquito attractants containing organic compounds; the attractant in the invention is formed by mixing caprylic acid and benzpyrole, wherein the concentration of the caprylic acid is 10mug / ml, and the concentration of the benzpyrole is 0.1-1mug / ml, and the caprylic acid and the benzpyrole are prepared by 1:1 of volume ratio; the application method is that: the attractant is arranged in the room or at the field and is released slowly and naturally; in the field, the attractant is arranged in a glass long-neck volumetric flask or is released by being arranged in glass long-neck bottles with corks or is used with an insect trap. In the invention, the attractant can effectively attract culex pipiens pallens, aedes albopictus and other mosquitos, and the drug diffusion is little, and the attraction efficiency is high.

The invention discloses an anti-mosquito finishing process of a textile fabric. The textile fabric is cotton, tencel, modal, blended cotton (viscose cotton, polyester cotton, polyamide cotton), silk, a wool cotton dyed fabric, a thin chemical fiber fabric, a pair of socks, a mosquito net and the like. The process comprises the steps of: selecting a mosquito repellent and a low-temperature fixative, carrying out nano microencapsulation on the mosquito repellent by utilizing a microencapsulation technology, carrying out anti-mosquito finishing on a textile fabric to form an anti-mosquito emulsion through the low-temperature fixative, dehydrating and curing to finally obtain the anti-mosquito finished fabric. The anti-mosquito fabric fabricated by the anti-mosquito finishing process has a fast mosquito killing function, a repelling rate of the anti-mosquito finishing process on aedes albopicus, culex pipiens pallens and the like is higher than 90 percent and an anti-biting rate of the anti-mosquito finishing process is 100 percent; the anti-mosquito fabric does not have bad influence on physical indices such as appearance, strength, moisture absorbing property and the like of the fabric; the anti-mosquito fabric has a good anti-mosquito effect after being washed 15 times; and the anti-mosquito finished fabric does not stimulate or cause allergy to skin, is safe and non-toxic to ahuman body, and is comfortable to wear.

The invention discloses a method for controlling Culex palustris by using Beauveria bassiana, which comprises the following steps: 1) cultivating Beauveria bassiana to obtain a culture of Beauveria bassiana; 2) cultivating Beauveria bassiana centrifuge and collect the sediment, mix the Beauveria bassiana sediment with brown sugar powder 2g, algae extract 1g and yeast extract powder 0.5g, and dry at 30-40°C to obtain Beauveria bassiana Mixture; polylactic acid 100g was dissolved in 500mL of acetone to obtain a polylactic acid solution; Beauveria bassiana mixture, polylactic acid and urea with different contents were mixed evenly to prepare a spray film solution containing urea with different contents; 3) using Expandable polystyrene beads are used to prepare pellet cores; and the pellet cores are sprayed multiple times to obtain mosquito control particles; 4) Sprinkling the mosquito control particles into water bodies that require mosquito control, That is to realize the prevention and control of mosquitoes. The invention has the functions of trapping mosquito larvae and killing mosquitoes.

Compositions described herein are purposed to attract gravid mosquitoes to oviposit in a preferred environment. The composition for directing the oviposition of mosquitoes comprises one or more attractants and N—P—K additive, wherein the N—P—K additive is mixture that contain chemical elements nitrogen, phosphorus and potassium. The attractants can be modified to provide a composition for facilitating the oviposition of different kind of mosquito. The composition described above, can be modified to provide a composition for facilitating the oviposition of the Anopheles species of Culicidae. The composition can also include cooked whey, n-heneicosane and / or tetradecanoic acid methyl ester to provide a composition for facilitating the oviposition of the Aedes species of Culicidae. The composition can also be modified to provide a composition for facilitating the oviposition of the Culex species of Culicidae.

The invention relates to a fruit-based culex attractant. The fruit-based culex attractant comprises, by mass, 1-50% of red berry pulp, 1-50% of banana pulp, 1-50% of sugar, 1-50% of red wine and the balance water, wherein the red berry pulp and the banana pulp are prepared from rotted or damaged red berries and bananas respectively. The fruit-based culex attractant is high in culex attracting ratio, wide in material source, cheap, environment friendly, convenient to use and non-toxic to people and livestock, thereby being a safe, environment-friendly, efficient, simple and convenient culex control product.
