Diamondback moth larvae are very small and delicate, developing very quickly. They are not cannibalistic unless environmentally stressed. Eggs should be surface sterilized for strong performance. This colony originated in a cabbage field outside Geneva, New York in 1988.
Benzon Research also maintains what is known in the literature as the "NO-QAGE strain" of B.t.-resistant P. xylostella. It was derived from crossing the susceptible "Geneva" strain with a population of field selected (evolved B.t. resistance) P. xylostella originally collected in Hawaii. The colony typically maintains a level of resistance to our internal Btk standard (various Cry proteins) that is approximately 500-1000x higher than the susceptible colony.
