Pesticide Sensitivity

In laboratory trials, dimethoate, thiacloprid, acetamiprid, sulfoxaflor, and deltamethrin caused severe mortality (IOBC class 4: 'very harmful') within 24 hours. Spirotetramat, spiromesifen, orange oil, and fluopyram+tebuconazole were classified as 'slightly effective' (IOBC class 1), indicating better compatibility with .

Taxonomic Status

The Discodes is classified in the Encyrtinae of Encyrtidae. The UCR Entomology Research Museum holds specimens of D. aeneus, D. anthores, D. arizonensis, D. coccophagus, D. discors, and D. yasnoshae among its Encyrtidae collection.
