The olfactory system of insects is important for behavioral activities as it recognizes internal and external volatile stimuli in the environment. Insect odorant degrading enzymes (ODEs), including antennal-specific carboxylesterases (CXEs), are known to degrade redundant odorant molecules or to hydrolyze important olfactory sex pheromone components and plant volatiles. Compared to many well-studied Type-I sex pheromone-producing lepidopteran species, the molecular mechanisms of the olfactory system of Type-II sex pheromone-producing Hyphantria cunea (Drury) remain poorly understood. In the current study, we first identified a total of ten CXE genes based on our previous H. unea antennal transcriptomic data. We constructed a phylogenetic tree to evaluate the relationship of HcunCXEs with other insects’ CXEs, and used quantitative PCR to investigate the gene expression of H. cunea CXEs (HcunCXEs). Our results indicate that HcunCXEs are highly expressed in antennae, legs and wings, suggesting a potential function in degrading sex pheromone components, host plant volatiles, and other xenobiotics. This study not only provides a theoretical basis for subsequent olfactory mechanism studies on H. cunea, but also offers some new insights into functions and evolutionary characteristics of CXEs in lepidopteran insects. From a practical point of view, these HcunCXEs might represent meaningful targets for developing behavioral interference control strategies against H. cunea.

Abstract Female pheromone glands of the leafroller Argyrotaenia sphaleropa were analyzed. Two acetates were identified as (11Z,13)-tetradecadien-1-yl acetate and (11Z)-tetradecen-1-yl acetate by comparison with synthesized references. The (11Z,13)-tetradecadien-1-yl acetate and the aldehyde (11Z,13)-tetradecadienal were synthesized via a Wittig reaction. A field-trapping test showed that a lure consisting of a mixture of (11Z,13)-tetradecadienal and (11Z,13)- tetradecadien-1-yl acetate in a 10:1-ratio produced the highest trap catches.

The sex pheromone glands of two females of the fall webworm Hyphantria cunea Drury (Lepidoptera Arctiidae) that were discovered in Auckland in March 2003 were extracted in hexane and were subjected to GCMS analysis Four compounds were identified (9Z12Z15Z)octadeca91215trienal (9Z12Z)octadeca912dienal (3Z6Z)9S10Rcisepoxyhenicosa36diene and (13Z6Z)9S10Rcis910epoxyhenicosa136triene The ratio of these four compounds in the gland extracts was 660627901 Except for a trace amount of the trienic epoxide detected in the New Zealand sample the ratio of the three other compounds was very similar to native North American females of this species A direct comparison between the synthetic commercial lure Nitolure and the sex pheromone gland of females found in New Zealand indicates that the sex pheromone gland contains significantly more of (3Z6Z)9S10Rcisepoxyhenicosa36diene than the synthetic lure while the lure lacks the trace amount of the trienic epoxide Therefore the effectiveness of Nitolure at trapping fall webworm in New Zealand remains uncertain
