“…In our study, caryophyllene is detected with the same sensitivity as anethole by the insect but induced a repellent effect in the behavioral test only at a higher dose. The detection of plant compounds or pheromones via olfactory receptors in phytophagous insects does not necessarily imply an important role for these cues in attraction or repulsive responses [ 37 , 38 ]. For example, the compounds limonene, citronellol, and nerol, elicited strong and moderate EAG responses in stable flies, but they elicited only low behavioral repellency [ 39 ].…”

Essential oils of aromatic plants represent an alternative to classical pest control with synthetic chemicals. They are especially promising for the alternative control of stored product pest insects. Here, we tested behavioral and electrophysiological responses of the stored product pest Tribolium confusum, to the essential oil of a Brazilian indigenous plant, Varronia globosa, collected in the Caatinga ecosystem. We analyzed the essential oil by GC-MS, tested the effects of the entire oil and its major components on the behavior of individual beetles in a four-way olfactometer, and investigated responses to these stimuli in electroantennogram recordings (EAG). We could identify 25 constituents in the essential oil of V. globosa, with anethole, caryophyllene and spathulenole as main components. The oil and its main component anethole had repellent effects already at low doses, whereas caryophyllene had only a repellent effect at a high dose. In addition, the essential oil abolished the attractive effect of the T. confusum aggregation pheromone. EAG recordings revealed dose-dependent responses to the individual components and increasing responses to the blend and even more to the entire oil. Our study reveals the potential of anethole and the essential oil of V. globosa in the management of stored product pests.

“…This synthetic pheromone significantly attracted 60 times more males than the natural pheromone produced by virgin females of N. elegantalis ( Jaffe et al, 2007). On the other hand, P228 was synthetized according to a study made by Badji et al (2003) based on an electroantennograph study showing that males were highly attracted to the component (E)-11-hexadecenol (E11-16: OH).…”

Neoleucinodes elegantalis Guenée (Lepidoptera: Crambidae) represents the most damaging pest of the Solanaceae family. Current studies have demonstrated that the species has differentiated into four races according to variations in female genitalia, wing morphometrics and sequencing of the cytochrome Oxydase (CO1) mitochondrial gene. The number of males captured in Colombia and Ecuador were registered using traps baited with two sex pheromone: Neolegantol ® and P228. These pheromones were synthesized using natural female pheromones collected in Solanum lycopersicum L. plantations in Venezuela. In Colombia, the number of male catches was significantly higher for Neolegantol ® than for P228 and this number was significantly higher on S. lycopersicum followed by S. quitoense and S. betaceum. The haplotype net obtained with the CO1 gene produced two main clusters: one cluster was comprised by specimens from S. lycopersicum and S. quitoense plants (both with medium sized female genitalia) and the other cluster by specimens from S. betaceum (large sized genitalia). The Neolegantol® pheromone was also tested in Ecuador, however, insignificant number of males were attracted. Results suggest that pheromone composition or concentration, host biotypes and geographic location are relevant to monitor populations of N. elegantalis. Further studies of the species should concentrate on establishing the pheromone composition and concentration among the four biotypes.

Resumo -O objetivo deste trabalho foi avaliar a preferência alimentar, o limiar de ingestão e o efeito tóxico de inseticidas associados a atrativos, em adultos de Neoleucinodes elegantalis. Foram testados os atrativos: melado e mel a 10%, extrato hexânico de frutos verdes de tomate a 0,4%, sacarose a 5%, suco de laranja e suco de uva a 30%, vinagre de vinho tinto a 10% e proteína hidrolisada a 5%. Com base no teste de preferência alimentar, foram selecionados os atrativos sacarose, melado, mel e suco de laranja, para determinar o limiar de concentração capaz de estimular a alimentação de adultos de N. elegantalis. Foi testado o efeito tóxico de inseticidas associados ao mel a 10%. A sacarose e o mel apresentaram o melhor resultado em relação ao número de pousos e ao tempo de pouso e de alimentação de adultos de N. elegantalis. Os inseticidas não afetaram negativamente a atração pelo alimento dos adultos de N. elegantalis. Carbaril, cartape, deltametrina, fenpropatrina, indoxacarbe, lambda-cialotrina e lufenurom provocaram 100% de mortalidade em adultos (machos + fêmeas), após 24 horas de exposição, e mostraram-se promissores para o uso em iscas tóxicas.Termos para indexação: Neoleucinodes elegantalis, controle comportamental, iscas tóxicas, limiar de resposta. Selection of attractive food sources and toxicity of insecticides in tomato fruit borer managementAbstract -This work aimed at evaluating the food preference, the threshold of food intake and the toxic effect of insecticides associated with attractive food sources on adults of Neoleucinodes elegantalis. The following attractive food sources were tested: molasses and honey at 10%, hexanic extract of green tomato fruits at 0.4%, sucrose at 5%, orange and grape juice at 30%, red wine vinegar at 10%, and hydrolyzed protein at 5% concentration. Based on the food preference test, sucrose, molasses, honey, and orange juice were selected to determine the threshold concentration capable of stimulating feeding in N. elegantalis adults. The toxic effect of insecticides added to honey at 10% was also tested. Sucrose and honey had the best results in terms of number of landings, landing time, and feeding time of adults of N. elegantalis. The insecticides did not affect negatively the attraction of N. elegantalis adults to the food sources. Carbaryl, cartap, deltamethrin, fenpropatrin, indoxacarb, lambda-cyhalothrin, and lufenuron caused 100% mortality of adults (males and females), after 24 hours of exposure, which suggests that they are promising for use in toxic baits.
