1. Soldiers Initiate Foraging Activities in the Subterranean Termite,Heterotermes tenuis

   Fabiana Elaine Casarin, Ana Maria Costa–Leonardo, Alberto Arab · 2008 · Journal of Insect Science

   Resumen

   Caste polyethism has been recorded in some termite species, however the foraging behavior of subterranean termites remains poorly known. Heterotermes tenuis Hagen (Isoptera: Rhinotermitidae) is a subterranean termite that is native to Brazil and is an agricultural and urban pest. The aim of this study was to investigate which caste acts as scouts when searching for food sources and determinate the percentages of each caste present in the foraging territories of field colonies of H. tenuis. Our results showed no significant differences among the caste proportions present in the foraging territories of the three colonies studied in the field. Laboratory experiments showed that minor soldiers were the most frequent initiators of foraging activities. This result suggests that the exploratory phase of the foraging behavior may be regulated by the number of soldiers present in the foraging territories of each colony.

   Resumen

   A phylogenetic analysis of Heterotermes from 63 locations in the West Indies and associated mainland is presented based on the DNA sequence of a portion of the mitochondrial 16S rRNA gene. Maximum parsimony analysis of the aligned Heterotermes species and the outgroup taxa resulted in a consensus tree with five distinct West Indian groups. Morphological characters and geographical distribution supported the resulting clades, which were given the following taxonomic assignments: Heterotermes cardini (Bahamas and Cuba); Heterotermes sp. (Bonaire, FL; Grand Cayman; Grand Turk; Jamaica; and St. Barthelemy), Heterotermes convexinotatus (Antigua, Barbados, Curacao, Dominican Republic, Martinique, Puerto Rico, St. Kitts, St. Maarten, Venezuela, and Virgin Island), and Heterotermes tenuis (Lesser Antilles except Barbados and Martinique, Ecuador, and Suriname). The Florida Heterotermes sp. is a known nonendemic population, whereas those on Barbados, Grand Cayman, Grand Turk, Martinique, St. Barthelemy, and elsewhere may harbor or consist solely of nonendemic populations.
