We used single-sensillum recordings to characterize male Heliothis subflexa antennal olfactory receptor neuron physiology in response to compounds related to their sex pheromone. The recordings were then followed by cobalt staining in order to trace the neurons' axons to their

We have discovered a type of sensillum on the antennae of male corn earworm moths, Helicoverpa zea, that houses two types of receptor neuron (RN) that explains both the upwind flight attraction of males to their own species' pheromone blend

We used single sensillum recordings to define male Helicoverpa zea olfactory receptor neuron physiology followed by cobalt staining to trace the axons to destination glomeruli of the antennal lobe. Receptor neurons in type A sensilla that respond to the major

In moth sex pheromone olfaction systems, there is a stereotypical co-compartmentalization of two or sometimes three olfactory receptor neurons (ORNs) within single trichoid sensilla on which pheromone-sensitive odorant receptors (ORs) are differentially expressed. In this issue of Chemical Senses, Krieger

Over the last 50 years, female-produced sex pheromones of moths have been subjected to intensive study. Most work has focused on their role in mate recognition, and little on any role they may have in mate assessment. This is largely

Sphingosine-1-phosphate (S1P) is a sphingolipid signaling molecule crucial for cell survival and proliferation. S1P-mediated signaling is largely controlled through its biosynthesis and degradation, and S1P lyase (S1PL) is the only known enzyme that irreversibly degrades sphingoid base-1-phosphates to phosphoethanolamine and

Binding properties of six heterologously expressed pheromone-binding proteins (PBPs) identified in the silkmoths Antheraea polyphemus and Antheraea pernyi were studied using tritium-labelled pheromone components, ( E, Z)-6,11-hexadecadienyl acetate ((3)H-Ac1) and ( E, Z)-6,11-hexadecadienal ((3)H-Ald), common to both species. In addition

Several sympatric lepidopteran species feed on maize plants, and the different components of their species-specific female sex pheromones may play a role in attracting conspecifics and/or deter heterospecific males. In this study, we analyzed the content of Mythimna unipuncta pheromone

CD33-targeted lipid nanoparticles (aCD33LNs) were synthesized for delivery of GTI-2040, an antisense oligonucleotide (ASO) against the R2 subunit of ribonucleotide reductase, to acute myelogenous leukemia (AML). These LNs incorporated a deoxycholate-polyethylenimine (DOC-PEI) conjugate, which has shown significant activity to facilitate

The female-produced sex pheromone of grape leaffolder, Desmia_funeralis (Hübner), has been identified as a blend of (Z,Z)-11,13-hexadecadienal, 11-hexadecynal, and (Z)-11-hexadecenal. The first two components were essential for attraction of male moths, whereas the third compound was not essential, but increased

(11Z,13Z)-11,13-hexadecadienal, the female sex pheromone of the navel orangeworm (Amyelois transitella), was synthesized from commercially available 10-bromo-1-decanol in a 27% overall yield (8 steps). The synthesis was achieved by using 10-iododecanal, trimethylsilylacetylene and (Z)-1-bromo-1-butene as the key building blocks, employing

Two Helicoverpa species, H. armigera and H. assulta use (Z)-11-hexadecenal and (Z)-9-hexadecenal as their sex attractant pheromone components but in opposite ratios. Since both female and male interspecific hybrids produced by female H. assulta and male H. armigera have been
