Abstract

Camu camu is one of the native fruits with a great economic potential for agroindustry and agro exportation. Edessa is one camu camu pest that produces in dry buds and fruits with a mark decolorated with concentric circles well marked and a central point when they feed. The aim of the current research was to determinate the biological cycle under laboratory conditions and population fluctuations of Edessa aff. aulacosterna. "Camu camu fruit stink bug" during January to November, 2004 in camu-camu culture, in development and production parcels located in flooded areas of restinga in Pucallpa, Ucayali, Peru. Eggs, nymphs and adults were colected to begin artificial rearing proceeding of distrit of Yarinacocha, Pucallpa, Ucayali, Peru. Development time of eggs to 1th nymphal ins tar was 5.1 days. 94.6% of egg hatchability, varied between 12 until 14 egg-laying was found. The time passed since eggs until III nymphal instar was 37.3 días and of III to V nymphal instar was de 81.9 days. Percentage of mortality of 2nd nymphal instar to adult was 98,1%. Adults collected were localized mainly on branches and stem of the plants, while nymphs were found in delicated buds. In relation to seasonal populations only were registered eggs laying throught the year in parcels in production. Differences between nymphs I to V and adults of Edessa aff. aulacosterna, in production and development plantations were not found. Only differences in dry and wet period in III to V nymphs instar in development camu camu plants were found. Edessa aff. aulacosterna mainly presented a contagious distribution. Suitable knowledge of bioecology of Edessa aff. aulacosterna permit improves strategy of pest control.
