The juvenile hormone analogue S-(+)-methoprene is used in combination with the trifluoro-nematicidal ester, so that the toxicity of the trifluoro-nematicidal ester to aedes aegypti larvae can be remarkably improved.

The invention belongs to the technical field of insecticides, and discloses an S-methoprene-containing mosquito-killing solid block formula and a process, the S-methoprene-containing mosquito-killing solid block formula comprises the following components by weight: 10% of an S-methoprene active compound, 58% of a carrier, 20% of a binder, 6% of a slow-release matrix, 4% of a lubricant, 0.5% of a synthetic antioxidant, 1% of an ultraviolet screening agent, and 0.5% of a plasticizer. The carrier is diatomite subjected to hydrophobic treatment, and the hydrophobic treatment process of the diatomite comprises the following steps: drying the diatomite at 120 DEG C for 2 hours, performing spraying treatment by using a 5% silane coupling agent, and activating at 80 DEG C for 1 hour. According to the scheme, HPMC E5 is adopted as a slow-release substrate, and a hydrophobic diatomite carrier and an optimization process are combined, so that stable release of S-methoprene is ensured, the lasting period is as long as 90 days or above, the sustained-release preparation is suitable for long-term storage scenes such as marine transportation, chemicals do not need to be supplemented midway, and the maintenance cost is remarkably reduced. As an internationally recognized safe biopesticide, the S-methoprene is free of ecological toxicity and meets the environmental protection requirement for prevention and control of input mosquito-borne diseases in international trade.

The invention relates to a solid molded body for external use against parasites on animals. The molded body of the invention includes, as active compounds, the combination of fipronil and bifenthrin. In addition, the insect growth regulators pyriproxyfen and methoprene may be added as additional actives.

Mosquitoes and mosquito-borne illness remain to significantly impact public health and human well-being nowadays. Mitigation by pesticides against larvae and adults has played a critical role in mosquito management. Larviciding is more cost effective than adulticiding in mosquito control operations. However, mosquito larvicides are historically low for numerous reasons. Currently larvicides with microbial and insect growth regulators (IGRs) account for most of the available products. Screening of new active ingredients (Als) or improvement of existing Als is desired to augment the arsenals for mosquito control. S-methoprene has been one of the main targets for research and development. The efficacy and safety of S-methoprene has been well documented since the late 1960s, and numerous products have been commercialized to combat pests of economic importance.
