MOREIRA, GRAZIELLE F et al. Laboratory rearing technique and biology of Mycotretus apicalis (Coleoptera: Erotylidae) on dried Pleurotus sajor-caju mushrooms. Rev. Colomb. Entomol. [online]. 2010, vol.36, n.2, pp.342-345. ISSN 0120-0488.

Mycotretus apicalis is an erotylid beetle that is commonly found in cultivations Pleurotus sajor-caju in Minas Gerais, Brazil and could potentially be a pest. The life cycle is studied for the first time by laboratory rearing using dried P. sajor-caju mushrooms as both a feeding resource and an oviposition substrate. M. apicalis species has a generation time of about three weeks, with the egg-adult period was about 22 days, four larval instars, and the average longevity for adults of 89.7 ± 32.89 days. These results suggest that the M. apicalis has a potentially high rate of population increase, indicating its great potential to be a pest insect.
