The invention relates to new pyrazoline derivatives having insecticidal activity; the new compounds can be represented by the general formula ##STR1## wherein R is an alkoxycarbonyl group having 2 to 6 carbon atoms, X and Y are equal or different and represent hydrogen atoms or halogen atoms, and n is 2, 3 or 4. After having been processed to compositions, the compounds may be used for the control of insects in a dosage from 0.01 to 1 kg of active substance per hectare.
该发明涉及具有杀虫活性的新型
吡唑啉衍
生物;新化合物可以用通式表示为 ##STR1## 其中,R是具有2到6个碳原子的烷氧羰基基团,X和Y相等或不同,表示氢原子或卤素原子,n为2、3或4。在制成配方后,该化合物可用于控制昆虫,剂量为每公顷0.01至1千克活性物质。
