I get infested plants of technical hemp (Cannabis sativa)on July 2011. The plants were sampled on one Moravian field (Czech Republic) and were heavily infested with the moth, respectively its caterpillars, hemp borers (Grapholita delineana). I work in Agritec. This firm cooperate on the research dealing with agronomical aspects of technical hemp growing in the Czech Republic.

I got infested plants of technical hemp on July 2011. The plants were heavily infested with larvae (caterpillars)and pupae. And also adults just were leaving the plants. It is sure that the adults (on photo) leaved the infested plants (technical hemp - Canabis sativa).
