“…IPM has been proven effective in many parts of the world and in the Caribbean. 17,28,32 Studies on IPM have documented that farmers who went through IPM training sprayed less often and reduced their use of more highly toxic pesticides while still achieving the same crop yields as before. 28 Restricting pesticide use, especially the most toxic pesticides will reduce cases of pesticide poisoning and present a pathway for preventive programs.…”

Pesticide poisoning is a major public health concern in developing countries. We conducted a population survey among farmers in three parishes of northwestern Jamaica to determine the occurrence of acute pesticide poisoning and to identify factors associated with pesticide poisoning. Approximately 16% of 359 farmers who participated in the study reported one or more incidents of acute pesticide poisoning within the last two years. Only 25% of the farmers reported ever receiving training in pesticide handling or safety. The majority (68%) of farmers who reported pesticide poisoning never sought medical attention for poisoning. The factors found to be associated with pesticide poisoning in this study indicate that implementation of specific intervention strategies and education of farmers is needed in order to improve safe handling, use and disposal of pesticides and reduce incidents of acute pesticide poisoning.

“…Biocontrol of pests has been proven effective worldwide and in the Caribbean. 17 In Jamaica, a number of studies have detected high levels of residues of the organochlorine pesticide, Endosulfan, in surface water and aquatic life. Endosulfan is used across the island to control pests on coffee plants.…”

“…80 Schroeder 81 evidenciou um feromônio produzido pelos machos, que atrai as fêmeas, e um feromônio produzido pelas fêmeas, que atrai os machos. Posteriormente, Beavers e colaboradores 82 sugeriram que o odor de plantas jovens de citros é o principal responsável pela agregação desses insetos e que as fezes no local de agregação podem servir como um atraente secundário para o sexo oposto.…”

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)....

“…Alternative strategies such as biological control are currently capturing the attention as methods to decrease soil pollution, while favoring costs for banana and plantain production. Several studies have applied this method by using insect enemies [23], fungal species such as Bauveria bassiana [24], and entomopathogenic nematodes to control C. sordidus populations [25]. However, these approaches still remain incipient.…”

With the increasing negative impacts of food production worldwide caused by pests, the recovery of native entomopathogenic nematodes (EPNs) is relevant, since they are adapted to local environments, entomofauna, and significant virulence. Therefore, the present study was designed to recover and understand the phylogenetic diversity of EPNs and their associated bacterial endosymbionts, from banana and plantain crops, as alternatives for the control of weevil species. An extensive sampling of western Colombia covered 325 ha, yielding the recovery of three EPNs’ isolates (0.49% of the samples). The molecular characterization included four mitochondrial and nuclear loci, which, after merging with the sequences of 48 species, confirmed the presence of Steinernema carpocapsae, the first report of S. costaricense in South America, and monophyly in most of the Steinernema clades. The tree topologies were consistent for the nuclear loci but not for mitochondrial, probably due to the high nucleotide substitution rate, deficit in the number of species available for these loci, and incomplete lineage sorting. The endosymbiotic bacteria associated with S. carpocapsae were identified as Xenorhabdus nematophila. However, the S. costaricense bacterial symbiont presented a genetic similarity to X. koppenhoeferi and X. khoisanae, which are still uncertain in their classification. The identification of S. costaricense in South America indicates the wide range distribution of this species in the Americas and its ability to persist in different soil types. For the first time, EPN isolation and phylogenetic characterization are directed to plantain and banana crops. Leveraging EPNs’ diversity promises novel applications for crop protection, while the genetic resources from the bacterial endosymbionts may provide metabolites with a wide spectrum of uses, either for agricultural or medicinal purposes.
