The present study investigated the trail-following behavior of the subterranean termiteCoptotermes gestroi(Wasmann Rhinotermitidae) under laboratory conditions. The results showed that workers were the first to initiate the exploration to the food source. When food was discovered they returned to the nest laying a trail for recruiting nestmates to the food source. In this situation, workers always traveled significantly faster when returning from the arenas. Both workers and soldiers were recruited to the food source; however, the soldier/worker proportion was higher during the first phase of the recruitment. When no food was available, the number of recruited nestmates and the speed on their way back to the nest were significantly lower. The results also showed that scout foragers always laid trail pheromones when entering into unknown territories, and that chemical signals found in the food could induce workers ofC. gestroito increase their travel speed.

ABSTRACT The subterranean termite Coptotermes gestroi (Wasman) (Isoptera: Rhinotermitidae) is considered one of the main pest species in urban areas in the Southeast Region of Brazil. For the control of this pest, the use of chemical insecticides is recommended, but this method is problematic in urban areas because of the risks of intoxication in the population and environmental contamination along with difficulties in isolating the treated areas. Therefore, it is necessary to find alternative methods aimed at minimizing the undesirable effects on the human population and the environment caused by termite control measures. The objective of this research was to evaluate the toxicity of several essential oils of Eucalyptus (E. camaldulensis, E. citriodora, E. tereticornis, E. pseudoglobulus, and E. maidenii) to the termite C. gestroi, under laboratory conditions. The oils were applied on filter papers that were infested with C. gestroi immediately after the treatment. The most toxic oil to the termite was E. citriodora, with the lowest lethal concentration (LC50: 0.63%) and the shortest lethal time (LT50: <1 h at 10%, LT50: 42.4 h at 1.25%). The least toxic oil was E. pseudoglobulus, with the highest lethal concentration (LC50: 3.66%) and the longest lethal time (LT50: 11.1 h at 10%; LT50: 473 h at 1.25%). These results indicate the potential for use of eucalyptus essential oils, especially for E. citriodora, for the control of C. gestroi. This article also provides information on the yield from essential oil extraction for different eucalyptus species.

Coptotermes Gestroi

Termite infestations in urban areas are a serious problem because they cause negative economic effects, reduce the esthetic value of buildings, damage crops, and require household repairs. Chemical controls are the most common method used against subterranean termites, and baiting has emerged as one of the prominent control methods. The goal of this research was to determine the efficacy of termite baiting by treating one of six active termite stations (selective baiting) with chlorfluazuron baits to eradicate six populations of subterranean termites. This work shows that the placement of chlorfluazuron baits in one of the active stations was sufficient to destroy a colony that was interconnected with multiple chlorfluazuron-free stations. In general, it requires an average of 4–8 weeks for a quantity of less than 300 g of chlorfluazuron bait to remove a termite infestation at the study site.
