These insects belong to the genus Hymenoptera, the family Braconidae, and the genus Bracon (Habrobracon). belonging to the type. This entomophagous is mainly recommended for biological use against pests in the form of tapeworms, mulberry moths and similar worms. Bracon is an external parasite that paralyzes the middle and adult larvae of the caterpillar and then lays 4-5 to 16 eggs on it. If there is a lot of prey, it will not lay its eggs on all the paralyzed worms. The eggs may be single or multiple. Each female can lay up to 400 or more eggs. Bracon overwinters under tree bark, plant debris and cuttings in the form of mature breeds. In addition to this entomophagous occurrence in nature, it is propagated in laboratory conditions by wax moth worms or mill moth worms. Methods for propagating this entomophagous in the laboratory under special mechanized devices have been developed. With the emergence of cotton bollworms in plants in biological control programs are distributed from 500 to 2000, depending on the number of pests per hectare (1: 10-15 ratio).

O bicudo-do-algodoeiro (Anthonomus grandis Boheman, 1843) (Coleoptera: Curculionidae) é praga limitante para a cultura do algodão, especialmente no Nordeste do Brasil. O presente estudo objetivou estimar os índices de infestação e fatores de mortalidade natural do bicudo-do-algodoeiro na região do município de Caraíbas, localizada no semi-árido do Sudoeste da Bahia. O experimento foi realizado em cultivo de algodão da cultivar BSR Aroeira, Fazenda Lagoa Seca, no ano de 2006. As avaliações foram semanais, em cinco pontos amostrais de 25m², com a coleta de botões florais caídos no solo. A infestação foi estimada por meio da contagem dos orifícios de oviposição e/ou, de alimentação e nos botões e, também, pela presença de uma das fases do bicudo no seu interior. Os fatores de mortalidade foram estudados por meio da dissecação dos botões, estimando-se os índices de predação, parasitismo, dessecação e doença. Os resultados obtidos permitiram concluir que o bicudo determina altos níveis de infestação na região, acima dos níveis de controle estabelecidos para a praga. Parasitismo, dessecação e predação, nesta ordem de importância, determinam alta taxa de mortalidade real da praga. Catolaccus grandis Burks 1954, (Hymenoptera: Ptelomalidae) e Bracon sp. (Hymenoptera: Braconidae) são parasitóides do bicudo-do-algodoeiro na Região Sudoeste da Bahia, sendo a primeira espécie predominante., The boll weevil (Anthonomus grandis Boheman, 1843) (Coleoptera: Curculionidae) is a pest that limits the production of cotton, especially in the North East of Brazil. The present study aimed to estimate the infestation index and natural mortality of boll weevil at Caraibas County, located in the semi-arid of the Southwest of Bahia. The experiment was performed using the cultivar BSR Aroeira, at Fazenda Lagoa Seca, in 2006. Weekly evaluations were performed, in five sampling areas 25m2, collecting blossoms fallen on the ground. The infestation was estimated by counting the oviposition punctures and /or the feeding on blossoms, and also by the presence of one of the phases of the boll weevil in the inside. Mortality factors were studied through the dissection of blossoms, estimating predation, parasitism, dissection and disease. The results obtained allowed to conclude that the boll weevil determines high infestation levels in the region. Parasitism, dissection and predation, following this order, determine high rates of real mortality of the pest. Catolaccus grandis Burks, 1954 (Hymenoptera: Pteromalidae) and Bracon sp.(Hymenoptera: Braconidae) are parasitoids of boll weevil reported in sothwestern Bahia, being the first one the predominant species.

Two new species of Triozidae (Psylloidea) from China producing sphere-shaped leaf galls on Ficus hainanensis Merr. & Shun., are illustrated and described. For the first time Psylloidea are reported as host of a species of Braconidae. The parasitoid belonging to the genus Bracon Fabricius, 1804, is illustrated and described as Bracon psyllivorus spec. nov.

Lorsque Coelaenomenodera, l'ennemi le plus important du palmier à huile en Afrique de l'Ouest, entre dans une phase de multiplication intensive, ses générations très marquées ne se recouvrent plus, ce qui entraîne une nette diminution de l'efficacité de ses parasites larvaires, d'autant plus que les jeunes larves (1er et 2e stades) ne sont pas ou peu parasitées. On a donc tenté de combler cette lacune dans le complexe parasitaire de ce ravageur en introduisant des parasites de diverses espèces d'Hispines s'attaquant aux palmiers ou cocotiers. Ainsi, à la suite de plusieurs missions, des parasites furent importés des Nouvelles-Hébrides (Pediobius parvulus Ferr.), de Colombie (Bracon sp. et Tetrastichus sp.), de Malaisie (Pediobius parvulus Ferr. et Sympiesis javanica Ferr.). L'élevage au laboratoire de ces parasites est plus ou moins aisé suivant les espèces. Les lâchers dans différentes palmeraies n'ont permis d'obtenir que l'installation de Pediobius parvulus (souche des Nouvelles-Hébrides) mais la population de ce dernier est toujours très faible et son rôle dans la limitation des foyers de pullulation de Coelaenomenodera est par conséquent nul; comme il ne s'attaque qu'aux larves âgées du ravageur, il entre en compétition directe avec les parasites larvaires locaux qui sont en outre mieux adaptés aux conditions climatiques
