Abstract:
Abstract Planotortrix excessana was found to include moths of two distinct pheromone-types which were not mutually attractive. Tetradecyl acetate and (Z)-8-tetradecenyl acetate were identified as pheromone components in one, and two other tetradecenyl acetates, probably (Z)-5-and (Z)-7-tetradecenyl acetate, in the other. By contrast with other pheromones reported from the tribe Archipini,⊿11-tetradecenyl compounds were not found in either pheromone-type.

Abstract:
Females of Callosobruchus spp. are known to produce sex pheromones that attract males. These sex pheromones cannot be adopted for use in pest management without first investigating the responses of the males in the windless conditions of storage environments. Consequently, behavioural bioassays of Callosobruchus subinnotatus Pic males were conducted in an olfactometer in the absence of air-flow. Under these conditions males were found to be able to follow odour trails to the source. However, the latency period was longer in diffusional bioassays than for insects in a Y-tube olfactometer that p

Abstract:
AbstractFemales of Heliothis zea (Boddie) were stimulated to produce pheromone by injection of brain – subesophageal ganglion homogenates. Females injected with this homogenate during the photophase produced the same amount of pheromone and same ratio of components as neck-ligated females injected during the peak of pheromone production. Decapitated females and isolated abdomens also produced pheromone when injected with the brain – subesophageal ganglion homogenate during the photophase. These data show that the neurohormone which stimulates pheromone production is not degraded by enzymes dur

Abstract We present research on the chemical ecology of 14 species of longhorned beetles (Coleoptera: Cerambycidae), in four tribes of the subfamily Cerambycinae, conducted in east-central Illinois over 8 yr. Adult males produce aggregation-sex pheromones that attract both sexes. Twenty independent field bioassays explored the pheromone chemistry of the species and tested the possible attractive or antagonistic effects of compounds that are not produced by a given species, but are pheromone components of other species.

Abstract:
Sex-specific pheromones are known to play an important role in butterfly courtship, and may influence both individual reproductive success and reproductive isolation between species. Extensive ecological, behavioural and genetic studies of Heliconius butterflies have made a substantial contribution to our understanding of speciation. Male pheromones, although long suspected to play an important role, have received relatively little attention in this genus. Here, we combine morphological, chemical and behavioural analyses of male pheromones in the Neotropical butterfly Heliconius melpomene. Fir

Pheromones are the basis of insect aggregation, mating, and other behaviors. Cucujoid grain beetles produce macrocyclic lactones as aggregation pheromones, yet research on their biosynthesis at the molecular level remains limited. The rusty grain beetle, C. ferrugineus, is an important economic species in China. Although two aggregation pheromone components have been identified, their suspected biosynthesis via the MVA pathway and the FAS pathway lacks molecular elucidation. Previous evidence supports that starvation affects the production of aggregation pheromones. Therefore, we constructed c

Abstract:
The article presents the results of assessing the biological effectiveness of the multicomponent composition of the codling moth sex pheromone under the climateric conditions of RM. In this study, the role of the minor component in the attractiveness of the multicomponent blend of codling moth sex pheromone was determined. In field monitoring trials, various concentrations of the minor component were tested (with decreasing values), the ratio of the components with the highest attractive ability was determined, the decrease of biologic activity of the minor component was directly influenced by

Abstract:
The antennae reaction of the males Heliothis armigera was estimated by means of the electroantenographic apparatus to the components obtained from the extract of the pheromone glands of the females. It was found that the main component (Z11-16Al) caused a well-pronounced reaction on the male antennae. It has been shown that the pheromone emitted by the females of the native population does not differ from the pheromone emitted by the females of the species Heliothis armigera, which lives in the geographical area of the Asian continent.

The scope of the research was to determine the biological efficiency of the multicomponent blend of Orienthal fruit moth sex pheromone in the apple orchard. The introduction of the minor component M1 in doses of 10% to the basic components on dispensers had led to a increase in number of males caught in sex pheromone traps by 1,7 times. While the male captures on traps where was added 10% of minor component M2 to the basic ones had led to a increase by 1,2 times. The minor component M2 in-crease of doses had led to a proportional decrease of the male caught in traps. Research will be continued

In Israel mating disruption sex pheromone is used in all cotton fields and recent repeated outbreaks of the pest populations has suggested a change in the population sex pheromone characteristics. The research goals were to (1) determine the change in pheromone characteristic of PBW females after long experience to Mating Disruption (MD), (2) to test the male’s antennae response (EAG) to pheromone characteristics of laboratory, naive females, and of field collected, MD experienced females, (3) to analyse the biosyn

Abstract:
This interdisciplinaray work combines expertise in engineering and entomology in Israel and the US, to develop an acoustic trap for mate-seeking female medflies. Medflies are among the world's most economically harmful pests, and monitoring and control efforts cost about $800 million each year in Israel and the US. Efficient traps are vitally important tools for medfly quarantine and pest management activities; they are needed for early detection, for predicting dispersal patterns and for estimating medfly abundance within infested regions. Early detection facilitates rapid response to invasio

The general objective of this study was to develop rationally designed mimetic antagonists (and agonists) of the PK/PBAN Np class with enhanced bio-stability and bioavailability as prototypes for effective and environmentally friendly pest insect management agents. The PK/PBAN family is a multifunctional group of Nps that mediates key functions in insects (sex pheromone biosynthesis, cuticular melanization, myotropic activity, diapause and pupal development) and is, therefore, of high scientific and applied interest.
