生物型

Occurrence, development, and mechanism of planthopper insecticide resistance are discussed, along with proliferation of the resistant biotypes. 對(duì)褐飛虱抗藥性的形成和發(fā)展及其抗藥性機(jī)理等方面進(jìn)行了綜述，并對(duì)該蟲的再猖獗進(jìn)行了探討。

Briselden AM, Hiller SL. Longitudial study of the biotypes of Gardnerella vaginalis. J Clin Microbiol 1990;28:2761. 吳愛武

RESULTS Eleven biotypes,18 antibioticgrams,9 serotypes and 18 plasmidgrams were detected in the 97 strains. 結(jié)果97株菌分11個(gè)生物型，18個(gè)抗菌譜型，9個(gè)血清型與18個(gè)質(zhì)粒譜型，但分型率高低不一。

The result of such combined effects of the genetic system and the environment is strong homozygosity of the biotypes found by the author. 遺傳系統(tǒng)和環(huán)境的這種聯(lián)合效應(yīng)的結(jié)果，使作者看到了生物型的強(qiáng)純合性。

The only disadvantage is that it may trigger the selection of new biotypes that are able to attack the resistance cultivars. 唯一不利之處是可能促進(jìn)新生物型的選擇，危害抗蟲品種。
