“…The results do not support the hypothesis that during the There was a limited effect of mulch level on the direction from which weevils were recaptured relative to the pheromone-baited traps. Weevil movement from a given direction relative to the pheromone trap has an association with the wind direction (Howse et al, 1998). The results of our study however showed that wind direction did not substantially influence trap catches.…”

Banana weevil (Cosmopolites sordidus) is a major pest in East Africa causing yield losses of up to 14 metric tonnes per hectare annually. A study was conducted in Uganda to determine the effect of mulching on banana (Musa spp. L.) weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae), movement relative to pheromone-baited traps. Three treatments were used to create different mulching levels: banana without mulch (control), banana with thin mulch (< 6 cm thick), and banana with thick mulch (15 cm thick). Pheromone traps were placed in the plots and weevil trap catches were monitored. Weevil catches in pheromone traps from both mulched and unmulched plots were generally similar. The mulching level had no effect on the ratio of males to females recaptured. The numbers of weevils captured in pheromone traps were lower than in the wet season and was not influenced by mulch levels. Mulching levels had a limited influence on the numbers of weevils recaptured from different directions. The results generally indicate that mulching has no effect on weevil catches in pheromone traps.

“…This hypothesis should be further tested by comparing the effectiveness of 3kPZS versus spermiated males in their natural habitat. Capture rates and effective distances of 3kPZS-baited traps were similar to or greater than those reported in insects (14); but unlike mixtures of insect pheromones that attract males, 3kPZS alone induced robust responses in females. These are distinct advantages of 3kPZS because removal of ovulated females will result in a proportional reduction in viable eggs, and thus be more effective than removal of males.…”

“…Therefore, our main objective in studying the behavioral response of ovulated females to 3kPZS is to assess the potential utility of 3kPZS in control of sea lamprey in the Laurentian Great Lakes (5). Over 3,000 insect pheromones have been identified (13) and mixtures of female pheromones are commonly used as agents to enhance male trapping efficiency and disrupt reproduction as benign alternatives to traditional pesticide treatments (14). 3kPZS offers an ideal model for developing pheromone-based vertebrate pest control because, unlike mixtures of insect pheromones that attract males, 3kPZS alone modifies the behavior of ovulated females in their natural habitat (7).…”

Female insect pheromone blends induce robust tracking responses in males and direct them into traps. In vertebrates, pheromones that induce strong and precise tracking responses in natural habitats have rarely been described. Here, we show in the sea lamprey (Petromyzon marinus), a vertebrate invader of the Laurential Great Lakes, that a synthesized component of the male mating pheromone, 7␣, 12␣, 24-trihydroxy-5␣-cholan-3-one 24-sulfate (3kPZS), when released into a stream to reach concentrations of 10 ؊14 , 10 ؊13 , 10 ؊12 ,10 ؊11 , or 10 ؊10 M, triggers robust upstream movement in ovulated females drawing Ϸ50% into baited traps. Experiments conducted in diverse stream segments demonstrate the level of behavioral response was not affected by habitat conditions and is effective over hundreds of meters. 3kPZS is equally effective at luring ovulated females as the whole pheromone blend released by males between 10 ؊14 and 10 ؊11 M. 3kPZS diverts ovulated females away from and disrupts orientation to male washings when applied at concentrations higher than washings. Indeed, a single pheromone compound is able to redirect female sea lampreys away from a natural pheromone source and lure them into traps, which should be more effective than targeting males when applied in population control. Our findings may spur the discovery of other potent and environmentally benign agents to combat biological invasion, a process accelerated by globalization, exacerbated by climate change, and costing the global economy US$ 1.4 trillion of damage annually.invasive species ͉ odorant tracking ͉ pest control ͉ odorant disruption ͉ jawless vertebrate

Next, these molecules are transported to the olfactory receptor neurons (ORN), located in the dendritic membranes at the antenna sensory bristles, driving the mosquito's attention to the potential meal.…”

Mosquitos são responsáveis pela transmissão de várias doenças causadas por vírus, parasitas e helmintos. Considerando o custo e a complexidade do tratamento dessas doenças, o uso de repelentes para proteção contra mosquitos vetores se torna uma alternativa interessante. Nesse contexto, no presente trabalho foram feitos estudos por ancoramento e dinâmica molecular (DM) de potenciais ligantes da proteína odorante do mosquito Anopheles gambiae (AgOBP 1 ), o principal vetor da malária. Os modos de ligação na AgOBP 1 de moléculas com conhecida atividade atrativa e dos principais componentes do óleo do cravo da índia (Syzygium aromaticum), com potencial atividade repelente, foram comparados com o conhecido repelente N,N-dietil-3-metilbenzamida (DEET). Os resultados sugerem que o acetato de eugenila é um repelente melhor do que o DEET e também revelam as principais características do sítio de ligação da AgOBP 1 importantes para o planejamento de novos e mais eficientes repelentes.Mosquitoes are responsible for conveying various diseases caused by viruses, parasites and helminthes.

Results suggest the eugenyl acetate as a better repellent than DEET and also reveal the main features of the binding site of AgOBP 1 important to the design of new and more efficient repellents.
