Researchers at UC-Riverside conducted genomic sequencing of five nematode families in work that could improve their performance as a biocontrol against insect damage to crops, says the university. The microscopic roundworms already were known as beneficial species and have been used in organic pesticides with limited effect. Assistant professor Adler Dillman, the lead researcher, says genomic sequencing may lead to better-acting biopesticides. The research broadened knowledge of nematodes in general and also found a number of genes that seem to be involved in making the tiny worms into parasites of insects. “We are excited to continue studying these in future experiments,” said Adler.
