“…The natural enemy of Microtheca species, Stiretrus decastigmus (Herrich-Schaeffer) (Hemiptera: Pentatomidae), has been recorded in the state of Rio Grande do Sul, southern Brazil, preying on larvae and adults of M. ochroloma (Poncio et al, 2010) and M. semilaevis Stal (Sturza et al, 2012). However, little is known of the biology of this predator, a promising agent for biological control programs targeting this pest.…”

Stiretrus decastigmus (Herrich-Schaeffer) (Hemiptera: Pentatomidae) is an important predator of the insect pest Microtheca ochroloma Stal (Coleoptera: Chrysomelidae). The present study investigated the pre-imaginal development of S. decastigmus at different temperatures. The temperatures were: 20, 25, and 30 °C, with a relative humidity of 70 ± 10% and a photofase of 12 h, and the nymphs were fed larvae of M. ochroloma. We evaluated the duration and viability of the egg and nymphal stages, the duration of each instar, and the predation potential. The incubation time decreased with increasing temperature, and the viability was highest at 25 °C. The duration of the nymphal stage was inversely proportional to the temperature, ranging from 18 days at 30 °C to 40.6 days at 20 °C. The highest S. decastigmus predation rates were found at 20 °C (90.4 larvae) and 30 °C (72.5 larvae). S. decastigmus showed the highest viability and lowest consumption of larvae of M. ochroloma at 25 °C.Keywords: Asopinae, Chrysomelidae, biological control, predator.

A comprehensive catalog is provided for most leaf beetles belonging to the Chrysomelinae subfamily, which are housed in the collections of two institutions in the state of Pará, located in northern Brazil: The Museu Paraense Emílio Goeldi (MPEG) and the Universidade do Estado do Pará (UEPA). The catalog includes detailed geographic distribution data for all species, along with new records and photographs (including two paratypes of Cryptostetha pereirai Bechyně, 1958, with descriptions of the aedeagus and spermatheca). Furthermore, information is provided on host plants, parasites, parasitoids, and predators associated with certain species.
