蚊能传播疟疾、乙型脑炎、丝虫病等,这是大家熟知的。蚊的发育经过四个阶段,即由卵变为孑孓,孑孓变蛹,蛹变蚊子。在昆虫学上称它为“完全变态”。在这四步变态中,卵、孑孓、蛹都不能离开水,否则它们就不能生存。了解孑孓的生态,就是要掌握它的生长规律,以便采取有效的灭蚊措施。 Mosquitoes can spread malaria, Japanese encephalitis, filariasis, etc., which is well known. Mosquito development through four stages, that is, from eggs into larvae, larvae become pupae, pupal change mosquitoes. In entomology it is called “perverted.” In this four-step metamorphosis, eggs, larvae and pupae can not leave the water, otherwise they can not survive. To understand the ecology of larvae, it is necessary to grasp its law of growth in order to take effective anti-mosquito measures.
