The Male Sex Pheromone of the Butterfly Bicyclus anynana: Towards an Evolutionary Analysis
This study provides one of the first integrative analyses of a MSP in butterflies, and Interestingly, the chemical structure of B. anynana MSP is similar to some sex pheromones of female moths making a direct comparison of phersomone biosynthesis between male butterflies and female moth relevant to future research.

Allelic variation in a fatty-acyl reductase gene causes divergence in moth sex pheromones
This is the first functional characterization of a gene contributing to intraspecific behavioural reproductive isolation in moths, highlighting the importance of evolutionary diversification in a lepidopteran-specific family of reductases. Expand
Semi–Selective Fatty Acyl Reductases from Four Heliothine Moths Influence the Specific Pheromone Composition
It is concluded that a pgFAR with broad specificity is involved in heliothine moth pheromone biosynthesis, functioning as a semi–selective funnel that produces species–specific alcohol product ratios depending on the fatty–acyl precursor ratio in the phersomone gland. Expand
Cracking the olfactory code of a butterfly: the scent of ageing.
It is shown that variation in the male sex pheromone composition indicates male identity and male age, and there may be no 'lek paradox' to resolve once the precise signal of importance to females is identified, as hexadecanal is, as expected, depleted in additive genetic variation. Expand
Identification, Synthesis, and Behavioral Activity of 5,11-Dimethylpentacosane, A Novel Sex Pheromone Component of the Greater Wax Moth, Galleria Mellonella (L.)
The identification of 5,11-dimethylpentacosane is an important step for the development of an efficient long-range attractant that will be integrated with other environmentally safe strategies to reduce damage to beehives caused by wax moths. Expand
Sex pheromone perception in male pine sawflies, Neodiprion sertifer (Hymenoptera; Diprionidae)
The pheromone perception system encountered in male pine sawfly, Neodiprion sertifer, antennae differs clearly from that observed in moths. Expand
Alarm Pheromones and Chemical Communication in Nymphs of the Tropical Bed Bug Cimex hemipterus (Hemiptera: Cimicidae)
The results suggest that pheromone-based pest control methods developed for C. lectularius could be applicable to C. hemipterus, with the unique nymph blend showing promising practical properties. Expand
Reaction conditions for the resolution of 2-methylalkanoic acids in esterification and hydrolysis with lipase from Candida cylindracea
SummaryWe have demonstrated resolution of 2-methylalkanoic acids using lipase from Candida cylindracea as a catalyst. The resolution of 2-methyldecanoic acid was more successful than that ofExpand
Assessing the taxonomic status of Osmoderma cristinae (Coleoptera : Scarabaeidae), endemic to Sicily, by genetic, morphological and pheromonal analyses
The genetic and morphological data support the divergence of the two species and confirm the species status for O. cristinae, while sex pheromones are confirmed to be invariant among different species of the genus Osmoderma. Expand
The enantioselectivity of Candida rugosa lipase is influenced by the particle size of the immobilising support material Accurel
Abstract When Candida rugosa lipase (CRL) was immobilised on the porous polypropylene carrier Accurel it was found that differences in the samples of the carrier influenced the enantiomeric ratio (E)Expand
