the mating disruption technique has been widely used for the control of several lepidopteran pests. in the present study, we assessed the efficiency of two formulations of splat neo, a wax emulsion containing e-11-hexadecenol, with and without the insecticide cypermethrin, in affecting mating disruption of neoleucinodes elegantalis (guenée). we also determined the best phenological age or stage...

the carob moth, ectomyelois ceratoniae (zeller), (lep.: pyralidae), is an importantly injourious pest on a wide range of plants throughout the world and as well a major pest of pomegranate orchards in iran. insight into the sexual behavior of an insect is indispensable for optimizing the application of pheromone in pest control strategies and while information on reproductive behavior being the...

applying a precise forecasting method is necessary to achieve acceptable results in ipm programs. performances of the wing and delta pheromone traps for forecasting the codling moth phenology were compared with physiological time data based on degree-hours. six pheromone traps (three wing and three delta style) were applied for the monitoring of the codling moth population. traps were placed in...

the leopard moth, zeuzera pyrina (l.) (lepidoptera: cossidae) is a serious pest of walnut and apple trees in iran. one of the control methods for this pest is the mass trapping of males using pheromone traps. to determine the best size and color of traps, four different colors (green, yellow, white, gray) and two different sizes (delta shape with standard adhesive surface, 19 × 22 cm and trapez...

Social insects exhibit complex and adaptive behavior. In particular, it is well known that ants solve difficult problems, for instance selecting the shortest pathway, by communicating with each other via pheromone. The fundamental question regarding pheromone communication is: How have the pheromone communication systems emerged? This paper introduces the ant foraging model for evolution of phe...

The homothallic filamentous ascomycete Sordaria macrospora possesses genes which are thought to encode two pheromone precursors and two seven-transmembrane pheromone receptors. The pheromone precursor genes are termed ppg1 and ppg2. The putative products derived from the gene sequence show structural similarity to the alpha-factor precursors and a-factor precursors of the yeast Saccharomyces ce...

In this paper, we discuss the concentration dependency of pheromone communication in swarm robotics. Instead of a pheromone trail and the insect antenna, we used ethanol and an alcohol sensor. This experimental system has a trade-off problem; high concentrations of the pheromone yield high signal strength but the signal duration is short, while low pheromone concentrations yield low signal stre...
