Vertically transmitted endosymbionts persist for millions of years in invertebrates and play an important role animal evolution. However, the functional basis underlying maintenance these long-term resident bacteria is unknown. We report that weevil coleoptericin-A (ColA) antimicrobial peptide selectively targets within bacteriocytes regulates their growth through inhibition cell division. Silencing colA gene with RNA interference resulted a decrease size giant filamentous endosymbionts,...
In moths, the components of female pheromone blend are detected in male antennae by olfactory receptor neurons (Ph-ORNs) expressing narrowly tuned receptors.Responses to sex pheromones have generally been thought be independent from odorant background.However, interactions between and plant volatiles reported at behavioral detection levels.To document mechanisms such interactions, we analyzed Ph-ORN responses Spodoptera littoralis main component, Z9E11-14:Ac, presence 4 monoterpenes.To mimic...
Circadian rhythms are observed in mating behaviors moths: females emit sex pheromones and males attracted by these rhythmic fashions. In the moth Spodoptera littoralis, we demonstrated occurrence of a circadian oscillator antenna, peripheral olfactory organ. We identified different clock genes, period (per), cryptochrome1 (cry1) cryptochrome2 (cry2), this Using quantitative real-time PCR (qPCR), found that their corresponding transcripts cycled circadianly antenna as well brain....
Many animals rely on chemical cues to recognize and locate a resource, they must extract the relevant information from complex changing odor environment. For example, in moths, finding mate is mediated by sex pheromone, which detected rich environment of volatile plant compounds. Here, we investigated effects background walking response male Spodoptera littoralis female pheromone. Males were stimulated combining pheromone with one three compounds, their paths recorded locomotion compensator...
Abstract This article documents the addition of 299 microsatellite marker loci and nine pairs single‐nucleotide polymorphism (SNP) EPIC primers to Molecular Ecology Resources (MER) Database. Loci were developed for following species: Alosa pseudoharengus, aestivalis, Aphis spiraecola, Argopecten purpuratus, Coreoleuciscus splendidus, Garra gotyla, Hippodamia convergens, Linnaea borealis, Menippe mercenaria, adina, Parus major, Pinus densiflora, Portunus trituberculatus, Procontarinia...
European corn borer (ECB) neonate larvae are capable of orienting towards maize odours and avoiding spinach odours. We previously reported that odours' attraction was dependent on the stimulus regime. This led us to propose could have a repellent or attractive effect depending their concentration. In this work, we tested hypothesis by evaluating avoidance ECB four concentrations each six single green leaf volatiles (GLVs); these commonly found in other plants. dose-dependent for all GLVs...
Abstract The enantioselective synthesis of both (4 R ,5 )‐ and S )‐4‐methyl‐5‐nonanol ( 1 ) was achieved by starting from an optically active epoxide 5 .

Many behavioral responses to odors are synergistic, particularly in insects. In beetles, synergy often involves a pheromone and plant odor, pest management relies on them for the use of combined lures. To investigate olfactory mechanisms, we need distinguish synergistic effects from additive ones, when all components mixture active. As versatile tools procedures were not available, developed bioassay, mathematical model evaluate between aggregation (P) host (kairomone: K) American palm...
