Exigências Térmicas e Estimativa do Número de Gerações de Argyrotaenia sphaleropa (Meyrick) (Lepidoptera: Tortricidae)

Abstract: -Argyrotaenia sphaleropa (Meyrick) is often found attacking Diospyros kaki fruits in southern region of Brazil. Duration and viability of the periods (eggs, larvae and pupae) and lifespan of the pest was studied under laboratory conditions in different temperatures. The experiment was conducted in climatic chambers under 60±10% RH and 14h photophase, at temperatures of 14, 18, 20, 22, 25, 28 and 30ºC, using artificial diet. Larval eclosion occurred in 5.9 to 25.4 days and larval period ranged from 13.9 to 91… Show more

“…On spring apple leaves, larval development period was 17.3 days and 18.6 days, for male and female larvae, respectively. In general, these results agree with those found by Manfredi-Coimbra et al (2001), who reported a duration period of 19.3 days for larvae of both sexes reared on artificial diet at 22ºC. On the other diets, the duration of larval development was, in all cases, above that reported.…”

“…Recently, it has also come to prominence in Brazil for the damage it causes to Diospyros kaki L., limiting or impairing fruit production (Manfredi-Coimbra et al 2001). The female lays the eggs in masses on the leaves, and when the larvae emerge they disperse in search of suitable feeding sites.…”

“…Seus prejuízos à fruticultura, tanto diretos quanto indiretos, estão associados à produção de caqui (MANFREDI-COIMBRA et al, 2001), maçã (BENTANCOURT & SCATONI, 1986;BENTANCOURT et al, 2003), pêra (NORA & SUGIURA, 2001), pêssego (BOTTON et al, 2003) e uva (BENTANCOURT & SCATONI, 1986;BENTANCOURT et al, 2003). A espécie tem se destacado como praga de fruteiras na região da Encosta Superior da Serra do Nordeste no Estado do Rio Grande do Sul (MANFREDI-COIMBRA et al, 2001;BOTTON et al, 2003), fato que ressalta a importância do desenvolvimento de estratégias para o manejo integrado de pragas (MIP), que mantenham sob controle a população do inseto na região (BOTTON et al, 2003).…”

“…Estudos em laboratório referentes à bionomia e ao comportamento reprodutivo do inseto foram desenvolvidos utilizando dietas naturais (BENTANCOURT & SCATONI, 1986;BENTANCOURT et al, 2003) e artificiais (MANFREDI-COIMBRA et al, 2001;2005). Contudo, informações relacionadas à influência da idade da fêmea no momento da cópula, na longevidade, padrão de oviposição, fecundidade e fertilidade ainda são desconhecidas e importantes para a elaboração de estratégias de manejo.…”
