Other claims from this paper (8)
- Observation Five nematode species differed significantly in virulence against pickleworm.
- Observation S. carpocapsae Mexican strain had the lowest LC50 and was more pathogenic than four other nematodes.
- Association Nematode infectivity was positively correlated with pickleworm mortality.
- Association Smaller nematode species were more infective and induced mortality faster.
- Observation First instars and pupae were less affected than older larvae and prepupae; pupae were particularly refractory.
- Observation Applied S. carpocapsae entered squash blossoms, persisted and infected pickleworms.
- Intervention effect Nematode applications reduced damage to squash blossoms and fruit.
- Intervention effect Weekly nematode application at 2.5 billion/ha protected squash fruit as well as permethrin.
