Behavioral and olfactory antennal responses of Solenopsis geminata (Fabricius) (Hymenoptera: Formicidae) workers to their dufour gland secretion.
Behavioral and electrophysiological tests were performed to evaluate the responses of workers of the ant Solenopsis geminata (Fabricius) from different size categories to Dufour gland extracts. Morphometric measures based in head widths across eyes were used to determine worker sizes. Trail following response of different worker sizes to Dufour gland extract from workers of different sizes was ...

Alate trapping studies of a monogyne population of the fire ant Solenopsis geminata indicate that two sizes of gynes are produced. Macrogynes, which participate in late spring and summer mating flights, are larger, fattier, and more than twice as heavy as microgynes, which participate in fall mating flights. Three patterns of gyne production were observed in 51 colonies studied: 35 produced mac...

Severe cutaneous allergic vasculitis in a 60 year-old Caucasian male following the bite of the tropical fire ant, Solenopsis geminata (F.) is reported. Over the course of 8 weeks, the pathology progressed from an extensive red papular urticaria to vasculitis with peri-vascular inflammation and ulceration of the skin on the feet, ankles and lower limbs. Many of the affected areas of the skin eve...
متن کاملMetapleural- and postpharyngeal-gland secretions from workers of the ants Solenopsis invicta and S. geminata.
Chemical analyses by GC-MS of the metapleural glands (MG) from workers of Solenopsis invicta and S. geminata revealed for the first time the chemical composition of these glands and showed small differences between the two species. The MG of both species contain oleic, stearic, linoleic, and palmitic acid. Both ants, in addition, have small but significant amounts of hydrocarbons in their MG re...
