“…It is possible that these subtypes are not specialized for pheromones but may interact with structurally similar compounds. Alternatively, it is conceivable that at least HR11 and HR13, which show very low expression levels in female antennae, may be involved in pheromone detection because autodetection of pheromonal compounds by females has been demonstrated for several moths species, including noctuids (35).…”

The remarkable responsiveness of male moths to female released pheromones is based on the extremely sensitive and selective reaction of highly specialized sensory cells in the male antennae. These cells are supposed to be equipped with male-specific receptors for pheromonal compounds, however, the nature of these receptors is still elusive. By using a combination of genomic sequence analysis and cDNA-library screening, we have cloned various cDNAs of the tobacco budworm Heliothis virescens encoding candidate olfactory receptors. A comparison of all identified receptor types not only highlighted their overall high degree of sequence diversity but also led to the identification of a small group of receptors sharing >40% identity. In RT-PCR analysis it was found that distinct members of this group were expressed exclusively in the antennae of male moths. In situ hybridization experiments revealed that the male-specific expression of these receptor types was confined to antennal cells located beneath sensillar hair structures (sensilla triochoidea), which have been shown to contain pheromone-sensitive neurons. Moreover, two-color double in situhybridization approaches uncovered that cells expressing one of these receptor types were surrounded by cells expressing pheromone-binding proteins, as expected for a pheromone-sensitive sensillum. These findings suggest that receptors like Heliothis receptor 14 -16 (HR14 -HR16) may render antennal cells responsive to pheromones.T he olfactory system of insects, most notably of moths, is renowned for its remarkable sensitivity and selectivity; it has been an invaluable model system for studying fundamental aspects of olfaction (1). Insects detect volatile chemostimulants by means of chemosensory neurons housing in multiporous cuticular hairs, comprising olfactory sensilla (2). These specialized cells generate electrical signals upon interaction with appropriate chemical compounds. Experimental evidence indicating that the underlying chemoelectrical transduction process is mediated by means of odor-activated G protein-secondmessenger cascades, a mechanism used by most chemosensory cells (3), supports the notion that receptors for odorous compounds in insects should be members of the G protein-coupled receptor superfamily; however, it was only with the aid of sequenced genomes that genes encoding candidate odorant receptors from insects were identified recently in fly (4-8), mosquito (9-11), and moth (12) models. Despite the progress in identification and characterization of insect olfactory receptors, receptors for insect pheromones are still elusive. This status is more noteworthy given that the pioneering work in identifying signaling molecules for communication between individuals was performed on insects; in fact, the first known pheromone (bombykol) was isolated from the silkmoth Bombyx mori (13,14). Pheromones, originally defined as chemical compounds that are produced and secreted by individuals and received by other members of the same species in which they release a de...

“…However, the response of unmated males to pheromone blends has been well documented in earlier studies 24 . Autodetection was earlier reported from other moths such as Panaxia quadripunctaria 14 , Choristoneura rosaceana 25 and Grapholitha molesta (Busck) 26 . The role of sensilla trichodea in the perception of sex pheromones of females in H. armigera and other moths was reported by earlier workers 27,28 .…”

Autodetection in <i>Helicoverpa armigera</i> (Hubner)

Autodetection is an olfactory behavioural process where the females of some species respond to their own pheromonal blends. Through electroantennogram studies it has been proved that the gravid females of Helicoverpa armigera (Hubner) respond to their pheromone blend consisting of Z-11-hexadecenal and Z-9-hexadecenal in the ratio 97 : 3. Male antennae respond more strongly than virgin female antennae. However, antennae of gravid females elicit strong response than unmated males. Also, males showed strong responses in cross-wind flying in wind tunnel experiments, when sex pheromone blends were used. Virgin females and gravid females showed poor response in wind-tunnel studies. The ovipositional experiment where gravid females were allowed to oviposit in the presence and absence of pheromone odours indicated that there was no difference in the number of eggs laid. Through morphological studies, it has been proved that the females also possess sensilla trichoidea, destined to perceive the pheromone blends, though lesser in number than the males. These results support the hypothesis that autodetection of sex pheromones exists in females of H. armigera and is thought to function as a mechanism to induce dispersal under high population densities.

“…by Le Conte and Hefetz 2008;Keller 2009;Kocher and Grozinger 2011). While detailed consideration of this issue lies beyond the scope of the current review, it is interesting to note that female pheromone autodetection has been documented in some moth species (Ochieng et al 1995;Schneider et al 1998). Intriguingly, ALs of queen bees contain a glomerulus of larger size, which could be a female macroglomerulus (Arnold et al 1988).…”

-The discovery of 'queen substance', and the subsequent identification and synthesis of key components of queen mandibular pheromone, has been of significant importance to beekeepers and to the beekeeping industry. Fifty years on, there is greater appreciation of the importance and complexity of queen pheromones, but many mysteries remain about the mechanisms through which pheromones operate. The discovery of sex pheromone communication in moths occurred within the same time period, but in this case, intense pressure to find better means of pest management resulted in a remarkable focusing of research activity on understanding pheromone detection mechanisms and the central processing of pheromone signals in the moth. We can benefit from this work and here, studies on moths are used to highlight some of the gaps in our knowledge of pheromone communication in bees. A better understanding of pheromone communication in honey bees promises improved strategies for the successful management of these extraordinary animals.queen mandibular pheromone / Apis mellifera / olfactory system / biogenic amines / juvenile hormone / ecdysteroids
