(Z)-3-dodecen-1-yl (E)-2-butenoate (1) identified as the sex pheromone of sweet potato weevil, Cylas formicarius Fabricius, has been successfully synthesized from 3-butyn-1-ol and 1-bromooctane as starting materials. The overall yield via four steps was 60 % calculated on 3-butyn-1-ol.

This study was carried out at Berket El-Sabaa province, Menoufia Governorate, Egypt, during the period from March to June 2014. The present study aimed to study, the efficiency of pheromone traps on population fluctuation of Tuta absoluta, to determine the most suitable insecticide and rate of some selected bio and chemical insecticides against T. absoluta larvae.

Sex pheromone communication in moths has attracted the attention of evolutionary biologists due to the vast array of pheromone compounds used, addressing questions of how this diversity arose and how male reception has evolved in step with the female signal.

Cell differentiation is mediated by synchronized waves of coordinated expression for hundreds to thousands of genes, and must be regulated to produce complex tissues and phenotypes. For many animal species, sexual selection has driven the development of elaborate male ornaments, requiring sex-specific differentiation pathways.

Evaluation of Sex Ph A field experiment was conducted in farmer’s field during the kharif season of 2014-15 under irrigated condition at Hittinahalli and Jumanal villages of Vijayapur district of Karnataka to evaluate the efficacy of different pheromone trap models as monitoring devices for brinjal shoot and fruit borer Leucinodes orbonalis. The water trap (WOTA) model had significantly highest number of moths catches (seasonal mean of 3.08 moths/trap/five days ) with lowest mean shoot damage (5.48 %) and lowest mean fruit damage (15.03 %) resulting into highest yield (489 q ha-1 ).

Almost every interpersonal interaction is mediated by the sex of the individuals involved. Visual, auditory, and olfactory cues provide individuals with the opportunity to discriminate the sex of others from a distance and so prepare sex-appropriate behaviours for any impending interaction.

Pheromones are found throughout the living world and are a primal form of communication. These chemical messengers are transported outside the body and have a direct developmental effect on hormone levels and/or behaviour. This review article aims to highlight the role of human pheromones in sex and reproduction. A review of published articles was carried out, using PubMed, medical subject heading (MSH) databases and the Scopus engine.

Molecular orbital calculations (AM1 type) were performed on the geometry optimized structures of various farnesal isomers and methyl esters of farnesoic acids. It has been found that the major component, E, E-farnesal, of the sex-pheromone for the rice moth, Corcyra cephalonica Stainton is chemically the most exothermic and stable of all the farnesal isomers.

AM1-type molecular orbital calculations were performed on the geometry-optimized structures of various 4-(1’, 5’ - dimethly -4’ - heptenylidene) -1- methylcyclohexene isomers. It was found that the major component (4Z, 4’E isomer) of the sex pheromone of Eurygoaster integriceps is very dissimilar in chemical composition to the other isomers, although the stabilities and heats of the formation characteristics are comparable.

We have characterized a glycosylated, 31 amino-acid peptide of 4932 Da isolated from Drosophila melanogaster males. The mature peptide contains a sugar moiety of 1184 Da at a NDT consensus glycosylation site and a disulfide bond. It is synthesized in the male ejaculatory duct via a 54 amino-acid precursor containing an N-terminal signal peptide and Arg-Lys at the C-terminus which is cleaved off during maturation. The gene contains an intron of 53 bp and is localized in the cytological region 99B of the D. melanogaster genome....
