Ocorrência de Térmitas Alados (Insecta: Isoptera) em floresta primária e áreas de policultivo na Amazônia Central

Abstract

The diversity of the alates of termites in a policulture system was compared with that of primary forest in Central Amazonian. From November 1994 to March 1996, two light traps and two flight traps were instded in the policulture system; and one light trap and two flight traps in the forest. Of the total of 48 morphospecies, I identífied in Termitidae: Syntermes sp.; in Kalotermitidae: Kalotermes sp., Neotermes sp., Gl'totermes sp., and Incisiterrnes sp.; in Rhinotermitidae: Rhinotermitinae and Heterotermes sp.. Terrnitidae was the most abundant family in the areas, foliowed by Kalotemiitidae and Rhinotermitidae in the policulture, happening the inverse in the forest. Termitidae and Kalotmitidae were more ftequent in September (forest) and October 1995 (policulture); Rhinotermitidae in December of 1995 (policulture), September 1995 and March 1996 (forest). For comparison, we used only the collections of the period of June 1995 to March 1996. Of the 44 morphospecies collected in this period, 14 occurred exclusively in the policulture, 12 only in the primary forest, and 18 were common to both areas. There was no similarity in the composition of the species of Rhinotermitidae in both areas. Thirty-two species were observed in the policulture system and 30 in the forest. For the fàmilies, the synchronism of the captures was abòut 10-25% when the captures in the sarne area with the same types of traps were compafed. The synchronism was lower (10-14%) when the areas were compared. To judge by the number of species observed in the policulture system in comparison to the prirnary forest, the potential for colonization by tennites of the cultivated areas is similar to the forest.
