ABSTRACT:
Novel plectoxins isolated from the Primitive Hunting Spider, Plectreurys tristis are described, and their amino acid sequences are presented. These are toxic to various groups of insects, including Lepidopterans. A particularly potent plectoxin is Plt-VI. The plectoxins may be cloned into a baculovirus vector and hasten its speed of kill.
