Research on the monitoring oriental migratory locust based on remote sensing retrieval of vegetation information 基于植被信息遙感反演的東亞飛蝗監(jiān)測(cè)研究
Reasons and characteristics of outbreak of oriental migratory locust locusta migratoria manilensis in nandagang , hebei province 河北省南大港農(nóng)場(chǎng)2002年夏蝗發(fā)生特點(diǎn)及原因淺析
There have been close relations between the occurrence / development of east asia migratory locusts in china and the change of the atmospheric circulation 摘要我國(guó)東亞飛蝗的發(fā)生發(fā)展與大氣環(huán)流的變化密切相關(guān)。
Kinetic studies demonstrated that general esterases in four oriental migratory locust populations hydrolyze - na , - nb , p - na and p - na as substrate . among the four substrates , - na seemed to be the most favorable substrate for general esterases of the locust 酉旨酶動(dòng)力學(xué)研究表明,東亞飛蝗中酷酶對(duì)a一a 、 a一b 、 p一a及p一a等四種模式底物均有水解活性,其中a一na為最適底物,而對(duì)p一a的水解活性較低。
General esterases of oriental migratory locust collected from the four locations were compared . general esterases were most concentrated in the thorax and abdomen , which showed 46 . 1 % and 36 . 1 % of total esterase activity in females , and 42 . 7 and 36 . 0 % in males , when using - na as substrate 東亞飛蝗中酷酶活性主要集中在胸部和腹部,水解a ~ na的酷酶活性在雌性東亞飛蝗中分別有46 . 1 %和36 . 1 %集中在胸部和腹部,在雄性中分別為42 . 7 %和36 % 。
Recently , the chinese plant protection agencies reported the growing hardships in controlling some field populations of oriental migratory locust with organophosphate ( op ) compounds . up to now there are more than 600 arthropod species with documented resistance to one or more insecticides and / or acaricides since resistance phenomenon was first described in san jose scale to lime - sulfur in washington in 1908 . enhanced metabolic detoxification and reduced sensitivity of insecticide target - sites are the two major mechanisms in resistance development , involving three primary metabolic enzymes of esterases , glutathione s - transferases and cytochrome p450 polysubstrate monooxygenases 代謝抗性是指對(duì)殺蟲劑起水解或隔離作用的酶發(fā)生改變,從而對(duì)殺蟲劑起到解毒作用,昆蟲主要解毒酶系有酯酶、谷胱甘肽- s -轉(zhuǎn)移酶、細(xì)胞色素p450單加氧酶等,這三種酶系任何一種的組成部分發(fā)生改變均會(huì)引起害蟲抗性的改變;靶標(biāo)抗性是指由于殺蟲劑作用靶標(biāo)敏感度降低而產(chǎn)生的抗性。
