Abstract

Baculoviruses from five hymenopteran and eighteen lepidopteran species were studied by electron microscopy. Ten samples belonged to the unicapsid (UC) and eight to the multicapsid (MC) type of nuclear polyhedrosis viruses. Five were granulosis viruses (GV). Average dimensions of polyhedra and granules were 0.2 - 2.0 ┬Ám and 340 - 370 x 190 - 200 nm, respectively. Polyhedra contained up to 200 viruses. Average virus lengths were 232 - 370 (UC), 326 - 385 (MC), and 282 - 311 nm (GV). MC viruses contained up to 17 capsids. Oval particles and abnormally long or short viruses and capsids were present in most samples. Viruses of abnormal length constituted up to 26% of particles.
