Sex pheromone production and perception in European corn borer moths is determined by both autosomal and sex-linked genes.
TLDR
Investigation of inheritance patterns in pheromonally distinct populations of European corn borers from New York State supports speculation that the Z morph is the ancestral and that the E Morph is the derived European corn borer population.

Orchid pollination by sexual swindle
TLDR
It is found that flowers of O. sphegodes produce the same compounds and in similar relative proportions as are found in the sex pheromone of its pollinator species, the solitary bee Andrena nigroaenea.

Functional specialization of olfactory glomeruli in a moth.
TLDR
It was determined that physiologically distinct types of pheromone receptor neurons project axons to different regions of the macroglomerular complex (MGC), which indicates that, at least through the first stage of synapses, olfactory information moves through labeled lines.

The Male Sex Pheromone of the Butterfly Bicyclus anynana: Towards an Evolutionary Analysis
TLDR
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.

Moth Pheromone Genetics and Evolution
TLDR
It is argued that there is no reason to dismiss species recognition as a possible cause of evolutionary change in moth sex pheromones and Mendelian genes controlling differences in mate choice and in the production of mate recognition signals have been found.

EVOLUTION OF REPRODUCTIVE STRATEGIES IN THE SEXUALLY DECEPTIVE ORCHID OPHRYS SPHEGODES: HOW DOES FLOWER-SPECIFIC VARIATION OF ODOR SIGNALS INFLUENCE REPRODUCTIVE SUCCESS?
TLDR
It is demonstrated that a plant may take advantage of the learning abilities of the pollinators and influence flower visitation behavior by varying the relative proportions of saturated esters and aldehydes between flowers of different stem positions, which minimizes learned avoidance of the flowers.

Sex pheromone mimicry in the early spider orchid (Ophrys sphegodes): patterns of hydrocarbons as the key mechanism for pollination by sexual deception
TLDR
Since alkanes and alkenes together were most attractive, it is concluded they constitute the bees' sex pheromone as well as the pseudocopulation-behavior releasing orchid-odor bouquet.

Molecular phylogeny of the subfamilies in Geometridae (Geometroidea: Lepidoptera).
TLDR
Molecular sequence data from three gene fragments were used to examine critically a provisional phylogenetic classification based on morphological characters of the Geometridae, one of the most species-rich families of moths, to explore further the relationship between Sterrhinae and Larentiinae, the question as to whether Ennominae actually represent a monophyletic group, and the relationships between Ennominee and some of the other subfamilies.

Allelic variation in a fatty-acyl reductase gene causes divergence in moth sex pheromones
TLDR
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.

Inheritance of olfactory response to sex pheromone components in Ostrinia nubilalis
TLDR
The spatial distribution of the newly induced organs of different types within a cluster appears random and indicates that every region in the observed sensory skin area is equally capable of differentiation into the receptor type which is coded by the organ-controlling substance specific to the regenerated nerve fiber.
