“…Occurrence of such disturbances is possibly associated with quality of coffee leaves as a food source of larvae of the coffee leafminer. Chemical composition in terms of both nutritional value and photochemical defenses can affect physiological processes in the insect leading to poor performance or even mortality (Auerbach et al 1995;Chapman 1998;Guerreiro Filho & Mazzafera 2000). Variation in L. coffeella mortality may be associated with seasonal variation of these factors in terms of host-plant phenology (Price 1991;Auerbach et al 1995).…”

The natural mortality of the coffee leafminer, Leucoptera coffeella (Guérin-Méneville) was investigated in three strata of coffee plant canopy for three seasons through construction and analysis of ecological life tables. Mortality of the leafminer was similar on all thirds of the canopy. Total mortality of immature stages was 95%, with 38.5, 43.8 and 12.7% occurring during egg, larval, and pupal stages. Rainfall killed 39.3% of eggs and larvae, and together with egg inviability (16.3%) and Vespidae (11.3%), were the highest mortality factors. Six wasp parasitoids caused 8% of larval mortality. Egg and larva were the critical stages. Variation in mortality was primarily associated with egg inviability, rainfall, and parasitism by Horismenus sp. (Hymenoptera: Eulophidae). Physiological disturbances during molting and metamorphosis also contributed for fluctuations in mortality of the leafminer. Tactics of integrated pest management to enhance natural mortality of the leafminer while conserving or augmenting the action of natural enemies are discussed.

“…The number of generations per year varies. Leafmining has evolved independently many times and is found in the Coleoptera, Diptera, Lepidoptera' and Hymenoptera (Auerbach et al 1995). All the species in this study are leafmining moths with multiple generations per year.…”

“…All the species in this study are leafmining moths with multiple generations per year. Leafminers were studied for four main reasons: (1) the most common insect herbivores we encountered in our study plots were leafminers, (2) we could measure area of leaf consumed by leafminers, (3) the leafmine leaves a permanent record of each miner's fate, and (4) leafminers cannot escape their mines and cadavers inside mines indicate host-plant induced death (Auerbach et al 1995).…”

Abstract. Most studies on the effects of elevated CO 2 have focused on the effects on plant growth and ecosystem processes. Fewer studies have examined the effects of elevated CO 2 on herbivory, and of these, most have examined feeding rates in laboratory conditions. Our study takes advantage of an open-top CO 2 fertilization study in a Florida scrub-oak community to examine the effects of elevated CO 2 on herbivore densities, herbivore feeding rates, and levels of attack of herbivores by natural enemies.Higher atmospheric CO 2 concentration reduced plant foliar nitrogen concentrations, decreased abundance of leaf-mining insect herbivores, increased per capita leaf consumption by leafminers, and increased leafminer mortality. As suggested by other authors, reduced foliar quality contributed to the increase in herbivore mortality, but only partly. The major factor increasing mortality was higher attack rate by parasitoids. Thus increasing CO 2 concentrations may reduce the survivorship of insect herbivores directly, by reducing plant quality, but also indirectly, by changing herbivore feeding and eliciting greater top-down pressure from natural enemies.

“…Os resultados sugerem que três "fatores" favorecem o desenvolvimento de P. citrella: presença de brotos, temperatura mínima superior a 10°C e precipitação e umidade relativa não intensas. Esses fatores possibilitam o vôo para dispersão e oviposição e permanência dos ovos na planta, pois as chuvas intensas podem desalojar ovos e/ou expor as larvas, além de diminuir a atividade dos adultos (AUERBACH et al, 1995). A temperatura parece ser limitante no início do ciclo de P. citrella, revelando pouca relação com a dinâmica populacional ao longo do ano.…”

O objetivo desta pesquisa foi avaliar a dinâmica populacional de Phyllocnistis citrella Stainton, (Lepidoptera: Gracillariidae), o minador-dos-citros, em pomares de tangerineira Citrus deliciosa Tenore variedade Montenegrina e de tangoreiro híbrido "Murcott" Citrus sinensis L. Osbeck X Citrus reticulata Blanco, com manejo orgânico, em Montenegro (29° 68'S e 51° 46'O), Rio Grande do Sul. Foram realizadas amostragens quinzenais de julho de 2001 a junho de 2003. Os brotos coletados foram examinados em laboratório e submetidos à análise do número de folhas por broto, a da presença ou ausência de minas, do número de minas, dos ovos, das larvas e das pupas de P. citrella. Em ambos os pomares não houve registro de minas de P. citrella no primeiro fluxo de brotação, de agosto a outubro. No ano I, as maiores densidades de minas foram registradas em meados de novembro, início de janeiro e início de abril, em ambos os pomares. No ano II, constataram-se as maiores densidades de minas e larvas em janeiro e em abril, em C. deliciosa, e de dezembro a março em "Murcott". Embora o número médio de brotos registrado tenha sido sempre maior em C. deliciosa, a colonização e o estabelecimento do minador-dos-citros seguiram o mesmo padrão em ambos os pomares. A temperatura mínima e média e a umidade relativa do ar foram os fatores abióticos que apresentaram maior influência no número de minas e de larvas de P. citrella.
