1. Antibacterial properties of contact defensive secretions in neotropical Crematogaster ants
Crematogaster ants use their contact venoms to compete with other ants. Although those venoms are used primarily as repellent and toxic secretions, they may have other functions. The present study aimed to test the antibacterial property of abdominal venom of three neotropical Crematogaster ant species (C. distans, C. pygmaea and C. rochai) against gram-nega

2. 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

3. Morphological, chemical and developmental aspects of the Dufour gland in some eusocial bees (Hymenoptera, Apidae): a review
Aspectos morfológicos, químicos e do desenvolvimento da glândula de Dufour em algumas abelhas eussociais (Hymenoptera, Apidae): revisão. Esta revisão aborda os mais recentes dados sobre a glândula de Dufour em algumas abelhas eussociais, considerando aspectos gerais da sua morfologia, do seu desenvolvimento, da natureza química da sua secreção, assi

4. Chemical composition of the dufour gland secretion in queens of Melipona bicolor (Hymenoptera, Meliponini)
Utilizando cromatografia gasosa acoplada à espectrometria de massa, descrevemos as diferenças na composição química da secreção da glândula de Dufour de rainhas virgens e fisogástricas de Melipona bicolor. A secreção da glândula de rainhas virgens consiste de hidrocarbonetos, enquanto a das rainhas fisogástricas contém, além de hidrocarbonetos

5. Size differences in the Dufour gland of Apis mellifera Linnaeus (Hymenoptera, Apidae) between and within the female castes
The Dufour gland is found closely associated with the sting apparatus of all hymenopteran females, playing multiple roles among bees. In Apis mellifera Linnaeus, 1758 the gland is connected to the dorsal vaginal wall and, in queens, it produces egg-marking pheromones. In workers the function of this gland is unknown, except by its capacity to mimic the queen

6. Cuticular hydrocarbons mediate discrimination of reproductives and nonreproductives in the ant Myrmecia gulosa
In many species of social insects, the cuticular hydrocarbons of adults vary with both colony identity and individual physiology (oogenesis). Such variations have been shown in some ants and social wasps to function in nestmate recognition, but as yet there is no demonstration of their use by workers to recognize egg layers. We report that in the ant Myr
