“…Dentre os principais fatores que limitam a produção e a exportação de goiaba, destacase a espécie Conotrachelus psidii Marshall, 1922 (Coleoptera: Curculionidae), popularmente conhecida como gorgulho-da-goiaba, considerada praga-chave da cultura em vários países produtores de goiaba na América do Sul, como Peru, Venezuela, Colômbia e Brasil (MARTÍNEZ; CÁSARES, 1981;MONROY;INSUASTY, 2006;VASQUEZ et al, 2002).…”

1 FABRICIO IGLESIAS VALENTE2 , VERA LÚCIA RODRIGUES MACHADO BENASSI 3 RESUMO-Considerada praga-chave da cultura da goiaba, Conotrachelus psidii Marshall (Coleoptera: Curculionidae) tem causado grandes prejuízos em vários países produtores desta fruta. A pesquisa objetivou avaliar os parâmetros biológicos da praga, sob condições controladas, através do desenvolvimento de uma técnica de criação que permitiu efetuar observações diárias de pré-pupas e pupas. Constatou-se que o substrato adequado para manutenção dessas fases foi o solo argiloso umedecido com viabilidade de 78%, sendo este o tipo de solo utilizado na técnica de criação, que foi desenvolvida para trabalhos em câmara climatizada, à temperatura constante de 25 ± 1º C, fotoperíodo de 12 horas e UR de 70% ± 10%. Quanto aos aspectos biológicos, a duração média do período de ovo, larva, pré-pupa, pupa e ovo-pupa foi de: 4,25; 12,2; 106,6; 14,88 e 138,4 dias, respectivamente. A duração média do período da fase adulta, no solo, início da alimentação, pré-oviposição, longevidade e pós-oviposição foi de, 22; 11; 51,9; 149,32 e 7,18 dias, respectivamente. O período médio de oviposição foi de 120,27 dias, com um número médio de 343,63 ovos por fêmea. A técnica de criação desenvolvida permitiu acompanhar diariamente o desenvolvimento de pré-pupas, pupas e adultos do gorgulho-da-goiaba, sem que eles necessitassem reconstruir nova câmara, mostrando ser menos estressante e onerosa do ponto de vista energético.

BIOLOGICAL ASPECTS AND TECHNICAL REARING OF GUAVA wEEVIL, Conotrachelus psidii MARSHALL (COLEOPTERA: CURCULIONIDAE)ABSTRACT-The species Conotrachelus psidii Marshall (Coleoptera: Curculionidae), considered a key pest of guava cultivation, is causing major damage in several producing countries of the fruit. The purpose of this study was to evaluate the biological parameters of the pest under controlled conditions, through the development of a rearing technique of pre-pupae and pupae that would allow daily observations. It was found that the substrate for an appropriate development of these phases was moistened clay soil (with survival rate of 78%). This soil type was used in the rearing method, which was developed to work in a climatic chamber at a constant temperature of 25 ± 1ºC, 12 h photoperiod and 70% RH ± 10%. The biological stages of the egg, larva, pre-pupa, pupa and egg-pupa lasted, on average, 4. 25, 12.2, 106.6, 14.88, and 138.4 days, respectively. The adult stages in the soil, beginning of feeding, pre-oviposition, longevity, and post-oviposition lasted on average 22, 11, 51.9, 149.32, and 7.18 days, respectively. The average oviposition period lasted 120.27 days, with an average of 343.63 eggs per female. By the proposed rearing method, the development of pre-pupae, pupae and adults of the guava weevil could be daily monitored, without requiring the construction of a new chamber by the insects, thus reducing stress and input in terms of energy.

“…Le pseudofruit, cependant, est localement très consommé et, en Amazonie, il provient de petits vergers plus [15,17,24]. Dans l'état d'Amazonas, au Brésil, l'anacardier est cité comme unique plante-hôte d'Anastrepha leptozona [25,26], bien que celle-ci soit connue sur d'autres plante-hôtes.…”

-Introduction. The cashew (Anacardium occidentale L.) is mainly grown for the production of cashew nuts, but also for the pseudofruit. The insect pests of the plant were studied in Peru, where this fruit is consumed. Materials and methods. Samples were taken from 1998 to 2005 in different localities of the department of Loreto in the Peruvian Amazon to identify insect pests of cashew. Field observations and laboratory farms were used to characterize the damage caused by each insect. Results. Seven species of insects cause significant damage: five species attack the pseudofruit: Acanthocephala parensis (Hemiptera: Coreidae), Anastrepha obliqua (Diptera: Tephritidae), Conotrachelus sp. (Coleoptera: Curculionidae), Trigona amalthea and T. amazonensis (Hymenoptera: Apidae). The pest Aphis gossypii (Hemiptera: Aphididae) infests the inflorescences, buds and young fruit. The larvae of Macrocopturus cf. tristis (Coleoptera: Curculionidae) develop in buds and young shoots. Three new species are pests which have not yet been reported. Conclusion. Given the potential of the cashew apple production and the possible development of the culture of the cashew tree in the Peruvian Amazon, a more extensive study of the insect pests is desirable.Amazon / Peru / Anacardium occidentale / Anacardiaceae / pests of plants / data collection / pseudofruits Principaux insectes nuisibles à l'anacardier en Amazonie péruvienne.

“…Les mouches des fruits (Tephritidae) avec plus de 250 espèces économiquement nuisibles (White et Elson-Harris, 1992), constituent un des problèmes entomologiques majeurs des mangues en Afrique de l'Ouest et dans le monde (Mwatawala et al, 2004 ;Rey et al, 2004 ;Vayssières et al, 2004Vayssières et al, et 2005Anonymes, 2006). Elles s'attaquent à plus de 50 espèces fruitières dont les agrumes et les baies (Oukil et al, 2002 ;Vasquez et al, 2002). Les mouches piquent essentiellement les fruits en pré-maturité ou en maturité (Quilici et al, 2005).…”

Fruit flies are a major pest of mangoes and other fruits in Côte d'Ivoire. In order to effectively control fruit flies, a test to evaluate the effectiveness of Great Fruit Fly Bait (GFFB) containing the active ingredient, Abamectin, was carried out in three orchards in the Odienné department. The reference control was the Success Appat (GF-120) added to an untreated control. The treatment was carried out on the entire elementary plot once a week for seven weeks. The treatment consisted of spraying the foliage of each treated tree (the fruits were not treated). After seven weeks of application, 100 mangoes were randomly harvested from each elementary plot. Those that are bitten were counted and incubated in the laboratory until the emergence of adult flies that were then identified. The results obtained on the three (3) orchards show that the level of mango infestation was low in orchards treated with GFFB (0.45 pupa per fruit per weight for the 1 Litre/ha dose and 0.04 pupa per fruit per weight for the 1.5 Litre/ha dose) and GF120 (0.36 pupe per fruit per weight). In contrast, in untreated plots, infestation levels were high (12.47 pupae per
