Notes on biology of the stink bug Cyptocephala alvarengai Rolston (Hemiptera: Pentatomidae) feeding on rice panicles.
The development of the stink bug Cyptocephala alvarengai Rolston (Hemiptera: Pentatomidae) was studied on rice panicles under laboratory conditions. Adults were collected in rice fields in Goianira, Goiás, Brazil. The number of eggs per egg mass ranged from 6 to 20, with a mean of 11.8 ± 0.8. The egg to adult developmental time was 33.2 d. Adult longevity ranged from 16 to 46 d. The pre-oviposition, oviposition, and post-oviposition periods were 7.0, 22.3, and 6.3 d, respectively. Fertility was 82.3%. Cyptocephala alvarengai presents biological similarities to other stink bugs that feed on rice panicles, and has potential as a rice pest.
