Gnamptogenys striatula

Gnamptogenys striatula W-DG Trail following 4-Methylgeranyl octanoate 131,decanoate 132, dodecanoate 133 [174]... 

Aggression is not always involved in reproductive regulation. In some species, like Gnamptogenys striatula, reproductive status is determined by mating. Nevertheless,... 

H. saltator produces less pronounced qualitative differences. Other ponerine ants that are generally characterized by smaller colony sizes and limited queen-worker dimorphism (Peeters, 1993) only show quantitative differences in their cuticular hydrocarbon profiles between reproductives and non-reproductives. Gamergates in Gnamptogenys striatula differ from non-reproductive workers by having increased relative amounts of ten cuticular...

Figure 6.26 Some homomono terpenes. Compounds a and b, decyl and dodecyl esters of 4-methylgeraniol, form the trail pheromone of the ant Gnamptogenys striatula, compound c, a bishomomonoterpene is also present in the gland mixture but does not contribute much to the pheromone blend. These compounds come from the Dufour gland...

The first homomonoterpene and bishomomonoterpene have recently been discovered. A mixture of decanoate and dodecanoate of the third form of homogeranyl pyrophosphate shown in Figure 6.22, AS,2E)-3,4,7-trimethyl-2,6-octadienol (Figure 6.26) have been found to be the trail pheromone of the ponerine ant Gnamptogenys striatula. The dodecanoate of the bishomomonoterpene (45, 2 ,6 )-3,4,7-trimethyl-2,6-nonadienol was also present but only marginally active in the pheromone.
