Vedclass · Answer

(B) $Bt$ cotton is genetically modified to express insecticidal proteins derived from the bacterium $Bacillus$ $thuringiensis$. These proteins are specifically toxic to certain orders of insects,primarily lepidopterans (e.g.,tobacco budworm,armyworm),coleopterans (e.g.,beetles),and dipterans (e.g.,flies,mosquitoes). $Bt$ cotton is not a universal pesticide; it does not provide resistance against all types of pests,such as sucking pests,fungal pathogens,or viral diseases. Therefore,it is only resistant to the specific groups of insects for which the $Cry$ proteins are effective.

$Bt$ cotton is resistant to pests,such as lepidopterans,dipterans,and coleopterans. Is $Bt$ cotton also resistant to other pests as well?
