為了檢測HMGR抑制劑的具體殺蟲活性,進行了JH生物合成抑制作用的測試、對害蟲胃毒作用的測試、對害蟲殺卵作用的測試以及對害蟲生長調節作用的測試

摘要:農藥作為防治病蟲害的一種重要工具,每年可為全世界挽回巨大的農作物損失以及經濟損失。傳統的殺蟲劑在快速處理害蟲,確保農作物的豐收和人類的健康等等方面做出了相當卓越的貢獻。但與此同時,由于人們對殺蟲劑的不合理的使用,再者有一些殺蟲劑本身本來就有的缺點,引發了許許多多問題:比如殘留問題、對環境造成污染的問題、對生態產生的負面影響問題、對生物健康狀況的負面作用問題等等。隨著人類環境保護意識的日漸加強,人類對賴以生存的生態環境質量要求愈來愈高,我們需要設計出更多的高效、安全、生態友好的農藥新品種。因此國家“十二五”科技支撐計劃提出了支持綠色生態農藥發展的規劃。如何快速有效地發現綠色生態的新農藥靶標和新農藥結構就顯得尤為重要。在此背景下,開啟了本實驗。為了檢測HMGR抑制劑的具體殺蟲活性,進行了JH生物合成抑制作用的測試、對害蟲胃毒作用的測試、對害蟲殺卵作用的測試以及對害蟲生長調節作用的測試。實驗結果表明本發明的化合物是優異的昆蟲保幼激素生物合成抑制劑,抑制中的濃度達到納摩爾每升。其活體殺蟲活性主要體現在優良的胃毒、殺卵和昆蟲生長調節作用。34788

Study on insecticidal activity of HMGR inhibitor
Abstract: Pesticides, as an important tool for insect disease prevention, can save huge crop losses and economic damages every year around the world. Traditional pesticides have made quite outstanding contributions in rapidly processing pests, ensuring the harvest of crops and human health, etc. But at the same time, due to the unreasonable use of pesticides, moreover there are some disadvantages in some pesticides, many problems are caused, such as residual problems, pollution to the environment, the negative effect on ecology and biological health condition, and so on. With the increasing of human environmental protection consciousness, our requirements on the quality of the survival ecological environment are higher and higher, and more efficient, safe, eco-friendly pesticide varieties should be designed. Therefore the national science and technology support program of "The 12th Five-Year Plan" put forward supporting plan for the development of green ecological pesticide, and how to quickly and efficiently find out new green ecological pesticides targets and pesticide structure is particularly important. Under this background, this experiment is conducted. To detect the specific insecticidal activity of HMGR inhibitor, it carried out JH biosynthesis inhibiting test, tests of stomach toxicity effect on pests as well as the function of killing pest eggs on growth regulation of insects. The experimental results showed that this compound invented was a superior insect juvenile hormone biosynthesis inhibitor, and the concentration of the inhibitor had reached nanomole per liter. Its living insecticidal activity was mainly reflected in stomach poison, eggs killing and insect growth regulation.
