Variation of Phyllocnistis citrella population and parasitism in citrus cultivars under organic management

Aspects of population dynamics of Phyllocnistis citrella (Lep.: Gracillaridae), the citrus-leafminer, were evaluated by fortnightly samplings from July/2004 to June/2005 in two organically managed orchards, one of tangerine Montenegrina cultivar (Citrus deliciosa) and the other of the tangor Murcott...

CITRUS CITRUS RETICULATA PHYLLOCNISTIS CITRELLA PARASITOIDES CONTROL DE PLAGAS DINAMICA DE POBLACIONES DENSIDAD DE LA POBLACION TRAMPAS CAPTURA ANIMAL EXPERIMENTACION EN CAMPO EXPERIMENTACION EN LABORATORIO BRASIL Aspects of population dynamics of Phyllocnistis citrella (Lep.: Gracillaridae), the citrus-leafminer, were evaluated by fortnightly samplings from July/2004 to June/2005 in two organically managed orchards, one of tangerine Montenegrina cultivar (Citrus deliciosa) and the other of the tangor Murcott (Citrus sinensis x C. reticulata), in Montenegro (29°37’51"S, 51°28’10"W), RS. In laboratory, the number of leaves, mines, eggs, caterpillars and pupae of P. citrella and of parasitoids were registered from each shoot. The colonization pattern and resource usage by the miner was similar in the orchards. The higher densities of mines, eggs, caterpillars and pupae of P. citrella were verified in summer and autumn. The average number of adults and immature was similar between cultivars. About 60% of the annual shooting escape from the miner attack. The parasitism was 23.3% in 'Montenegrina' and 24.9% in 'Murcott'. The drought periods along the study may have influenced the miner and parasitoid populations. Avaliaram-se aspectos da dinamica populacional de Phyllocnistis citrella (Lep.: Gracillariidae) (minadordos- citros) e de seus parasitóides por amostragens quinzenais de julho/2004 a junho/2005 em dois pomares sob manejo organico, um de tangerineira 'Montenegrina' (Citrus deliciosa) e outro do tangoreiro 'Murcott’ (Citrus sinensis x C. reticulata), em Montenegro (29°37’51”S, 51°28’10”W), RS.Em laboratório registrou-se dos brotos, o número de folhas, minas, ovos, lagartas e pupas de P. citrella e de parasitóides. O padrao de colonizaçao e uso do recurso pelo minador foi semelhante nos pomares. No verao e outono, verificaram-se as maiores densidades de minas, ovos, lagartas e pupas de P. citrella. O número médio de adultos e imaturos de P. citrella foi semelhante entre as variedades. Cerca de 60% da brotaçao anual escapa do ataque do minador. O parasitismo foi de 23,3% em 'Montenegrina' e 24,9% em 'Murcott'. Os períodos de estiagem durante o trabalho podem ter influenciado as populacoes do minador e de parasitóides. 2015-03-19T22:15:55Z 2015-03-19T22:15:55Z 2006 Artículo 471597 1659-0082 https://repositorio.catie.ac.cr/handle/11554/6919 en Manejo Integrado de Plagas y Agroecología Número 78 (Agosto 2006) https://creativecommons.org/licenses/by-nc-nd/4.0/ pdf application/pdf CATIE, Turrialba (Costa Rica)
