“…Insect response to an aggregation pheromone is known to be largely affected by physiological state (e.g., hunger, mating condition, age, and molting cycle) and extrinsic factors (e.g., time of day, season, density of conspecifics of same or opposite sex, and temperature) (Aller & Cladwell, 1979;Bartelt & Jackson, 1984;Joosse, 1970;Lorenzo Figuerias et al, 1994;Mayhew & Phillips, 1994;Schaner et al, 1989). Many species are known to respond to aggregation pheromones when they are accompanied by odors of food or breeding substrates or other coattractants (Phillips and Burkholder, 1981;Ramirez-Lucas et al, 1996;Wertheim et al, 2005). Furthermore, release of aggregation pheromones is also influenced by presence of conspecific eggs, larvae, or pupae as well as adult density at the release site (Wertheim et al, 2005).…”

Chemical and behavioral analysis of the cuticular hydrocarbons from Asian citrus psyllid, Diaphorina citri

Huanglongbing (HLB) is the most destructive disease of citrus worldwide. The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Psyllidae), is the vector of the phloem-inhabiting bacterium, Candidatus Liberibacter asiaticus, which is presumed to cause HLB in Florida citrus. Laboratory and field studies were conducted to examine the behavioral responses of male and female D. citri to their cuticular extracts. In olfactometer assays, more male D. citri were attracted to one, five, or 10 female cuticular extract equivalent units than blank controls. The results were confirmed in field studies in which clear or yellow traps baited with 10 female cuticular extract equivalent units attracted proportionately more males than clear traps baited with male cuticular extract or unbaited traps. Analyses of cuticular constituents of male and female D. citri revealed differences between the sexes in chemical composition of their cuticular extracts. Laboratory bioassays with synthetic chemicals identified from cuticular extracts indicated that dodecanoic acid attracted more males than clean air. Traps baited with dodecanoic acid did not increase total catch of D. citri as compared with blank traps at the dosages tested; however, the sex ratio of psyllid catch was male biased on traps baited with the highest lure loading dosage tested (10.0 mg).

“…Similarly, significantly more unmated females of Metamasius hemipterus were attracted by the aggregation pheromone in laboratory bioassays (Ramirez-Lucas et al, 1996). Searching for males to mate with could be the reason why unmated female responded more than mated female C. sordidus to the aggregation pheromone.…”

The banana (Musa spp.) weevil (Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) is a major pest in East Africa causing yield losses of up to 14 metric tonnes per hectare annually. Laboratory and field experiments were conducted to determine whether the response of the banana weevil, Cosmopolites sordidus (Germar) (Coleoptera: Curculionidae) to its aggregation pheromone was influenced by age, female mating status and weevil density. Laboratory bioassays were conducted using a double pitfall olfactometer, while a bucket pitfall trap was used in field experiments. There was no significant (P>0.05) difference in response to pheromone between immature and mature weevils (males and females) in laboratory bioassays. Forty-day-old weevils had a stronger response to the pheromone than 10-day-old ones under field conditions. The response of unmated weevils to the pheromone was stronger than that of mated weevils, both in the laboratory and field. The percentage of unmated and mated weevils recaptured from 0 and 3 m were similar but significantly different from 6 m way from the pheromone baited trap. The response of the weevils to the pheromone was not significantly (P>0.05) influenced by its previous density.

“…Por outro lado, a adição dos compostos 19 e 20 não aumentou a atração dos insetos. 37 Perez e colaboradores 38 verificaram a presença de um feromônio de agregação produzido pelos machos da subespécie M. hemipterus sericeus. Eles encontraram todos os compostos já descritos por Ramirez-Lucas e colaboradores, 35 exceto os compostos 19 e 20.…”

Recebido em 26/9/08; aceito em 24/4/09; publicado na web em 7/10/09 AGGREGATION PHEROMONE IN CURCULIONIDAE (INSECTA: COLEOPTERA) AND THEIR TAXONOMIC IMPLICATION. The pheromones of the weevils has been the most studied and used so far for Coleoptera species. The majority of reported weevil pheromones is produced by males and usually attract both sexes. The identified pheromone compounds are classified in two categories: ten-carbon compounds with terpenoid branching and compounds of various sizes, apparently of fatty-acid origin. These pheromone structural categories are consistent within subfamilies. This review aims to give an overview of the aggregation pheromones identified for Curculionidae pests, describing the relationship of the molecules structural pattern among subfamilies, and propose an identification key based on the structure of the pheromone components.Keywords: weevils; pheromone structure; identification key. INTRODUÇÃOOs curculionídeos são besouros da superfamília Curculionoidea, com cerca de 60.000 espécies descritas.1 Os adultos da família Curculionidae são facilmente reconhecidos pela presença de uma cabeça prolongada em um rostro de comprimento muito variável, assim como antenas genículo-clavadas 2 (Figura 1). Os curculionídeos, em sua grande maioria, são fitófagos, tanto na fase larval como na adulta. 3Muitas espécies são importantes pragas de diversas culturas, bem como de grãos armazenados, e a necessidade constante de medidas de controle mais efetivas e seguras ao meio ambiente tem exigido da comunidade científica a busca por novos métodos de controle para minimizar o impacto desses insetos. Como em outros grupos de insetos, esta necessidade tem aumentado a investigação do uso de feromônios como mais uma ferramenta no manejo dessas pragas. Um trabalho extensivo tem sido feito na identificação de feromônios e seu uso dentro da família Curculionidae, 4 exemplificado pelas décadas de pesquisa conduzidas com o bicudo do algodoeiro, Anthonomus grandis.5 Seguindo a identificação de quatro componentes do feromônio de agregação de A. grandis, 6 feromônios de várias espécies de curculionídeos têm sido identificados.A maioria dos feromônios relatada em curculionídeos é produzida pelos machos e usualmente atrai ambos os sexos, por isso são conhecidos como feromônios de agregação. Entretanto, alguns feromônios também têm sido verificados em fêmeas. Estes incluem feromônios sexuais de longa-distância, que atraem principalmente machos, curta-distância ou feromônio de contato, que permitem reconhecer coespecíficos e feromônio de oviposição, que algumas fêmeas usam para marcar os hospedeiros, nos quais elas colocam seus ovos. Finalmente, existem exemplos de curculionídeos utilizando feromônios de outras espécies de besouros, como cairomônios. 4 Em virtude de seus hábitos de vida, o estudo comportamental de curculionídeos é relativamente complexo. Uma alternativa que evita muitos problemas com bioensaios e acelera o processo de identificação é a cromatografia gasosa acoplada à eletroantenografia (CG-EAG)....
