Abstract
This micro-organism is being used with considerable success against the larvae of various Lepidoptera. Spores, obtained from laboratory cultures, are applied as dusts or powders to the host plant of the insect and when ingested by the latter, produce a disease which is quite long-lasting. Results in the laboratory and in the field are reported and the percentage of insect mortality ranges from 100 to 62-5%. Since the product is not toxic, the treated plants can be used as food without danger to the consumer.
