About Steinernema carpocapsae

Steinernema carpocapsae is a parasitic nematode capable of infecting a broad range of insect species. The infective juvenile, which emerges from a depleted host cadaver to seek out a new insect to infect, is the only free-living stage. Infective juveniles tend to be found at the soil surface, and use an ambushing search strategy in which they stand on their tails and attach to a passing insect.

Genome Assembly & Annotation


The genome assembly was produced by the University of California, Irvine using PacBio long reads, with BioNano optical mapping, as described in Serra et al. (2019). It is an update to an earlier assembly from the same institute.


The gene predictions were made using AUGUSTUS incorporating evidence from open reading frames, RNASeq data across multiple developmental stages and conditions, and alignments from C. elegans. The gene models were updated in release 15 to incorporate UTRs.
