Open AccessOvipositional responses of tortricid moths to sugars, salts and neem oil
Oviposition is essential in the life history of insects and is mainly mediated by chemical and tactile cues present on the plant surface. Oviposition deterrents or stimulants can modify insect oviposition and ...

Open AccessGustatory function of sensilla chaetica on the labial palps and antennae of three tortricid moths (Lepidoptera: Tortricidae)
In adult Lepidoptera the labial palps are best known for their role in CO2 detection, but they can also bear sensilla chaetica which function is unknown. The number and distribution of sensilla chaetica in labial...

Open AccessA closer look at sex pheromone autodetection in the Oriental fruit moth
Female moths emit sex pheromone to attracts males, and although they are not attracted to their own sex pheromone, they appear to detect it as it affects their behavior. In order to elucidate the mechanism of ...

Open AccessExtremely low neonicotinoid doses alter navigation of pest insects along pheromone plumes
The prevailing use of neonicotinoids in pest control has adverse effects on non-target organisms, like honeybees. However, relatively few studies have explored the effect of sublethal neonicotinoid levels on o...

Captures of oriental fruit moth, Grapholita molesta (Lepidoptera: Tortricidae), in traps baited with host-plant volatiles in Chile
Studies in Australia and China identified host-plant volatile blends from peach and pear that captured relatively high numbers of Grapholita molesta (Busck). To determine if these blends are attractants in other ...

Sublethal Effects of Neonicotinoid Insecticide on Calling Behavior and Pheromone Production of Tortricid Moths
In moths, sexual behavior combines female sex pheromone production and calling behavior. The normal functioning of these periodic events requires an intact nervous system. Neurotoxic insecticide residues in th...

Substrate-Borne Vibrational Signals in Mating Communication of Macrolophus Bugs
The mirid bugs Macrolophus pygmaeus and M. costalis use substrate-borne vibrational signals during pair formation and in male-male interactions as determined by laser vibrometry. The vibrational communication of

Three-dimensional antennal lobe atlas of the oriental fruit moth, Cydia molesta (Busck) (Lepidoptera: Tortricidae): comparison of male and female glomerular organization
The oriental fruit moth Cydia molesta is an important pest and the behavioural role of olfactory signals such as pheromones and plant volatiles have been studied extensively in both sexes. To understand odour pro...

Sexual Approach in the Praying Mantid Mantis Religiosa (L.)
Males of sexually cannibalistic species are thought to express behaviors that reduce the risk of being killed by the females. In several spider species the male modulates his approach to the female as a functi...

Pheromone Antagonism in the European Corn Borer Moth Ostrinia nubilalis
Mixing the sex pheromones of the Mediterranean corn borer, Sesamia nonagrioides, and the European corn borer, Ostrinia nubilalis, results in significantly lower captures of O. nubilalis when compared to traps loa...

Nocturnal Calling Behavior in Mantids
Females of Mantis religiosa and Empusa pennata were video taped for several 24 h periods to determine if they showed behaviors associated with pheromone release. In the photophase the abdomen of both species was ...

Behavioral and Electrophysiological Responses of the Brownbanded Cockroach, Supella longipalpa, to Stereoisomers of Its Sex Pheromone, Supellapyrone
Females of the brownbanded cockroach, Supella longipalpa, release a sex pheromone (supellapyrone) during a calling behavior and attract males from a distance. Supellapyrone has four possible configurations result...

Behavioral and Electrophysiological Evidence for Volatile Sex Pheromones in Parcoblatta Wood Cockroaches
Species within the cockroach genus Parcoblatta are sexually dimorphic for wing length; females have reduced wings and are flightless, while males have long wings that are used in flight. We predicted that Parcobl...

Quantitative Genetics of Signal Evolution: A Comparison of the Pheromonal Signal in Two Populations of the Cabbage Looper, Trichoplusia ni
Pheromones are important in reproductive isolation among populations of moths, but the genetics associated with diversification of pheromonal signals is poorly understood. To gain insight into processes that m...

Aggressive Chemical Mimicry by the Bolas Spider Mastophora hutchinsoni: Identification and Quantification of a Major Prey's Sex Pheromone Components in the Spider's Volatile Emissions
The adult female bolas spider Mastophora hutchinsoni feeds exclusively on attracted males of a few moth species. This exclusivity and the behavior of the approaching moths suggest that the spider aggressively mim...

Chemical and Behavioral Evidence for a Third Pheromone Component in a North American Population of the Black Cutworm Moth, Agrotis ipsilon
The sex pheromone of Agrotis ipsilon had been previously identified as a blend of (Z)-7-dodecenyl acetate (Z7–12:Ac) and (Z)-9-tetradecenyl acetate (Z9–14:Ac). A synthetic blend of Z7–12:Ac and Z9–14:Ac (30 μg:10...
