Targeted precision biocontrol and pollination enhancement in organic cropping systems

Controle massal da broca‑do‑café com armadilhas de garrafa Pet vermelha em cafeeiro

The objective of this work was to evaluate the efficacy of red PET‑bottle traps, containing attractive alcoholic volatile compounds, in the mass control of coffee berry borer (Hypothenemus hampei). The evaluations were carried out in four coffee crops, during two years. Nine hundred PET‑bottle traps, painted red, were distributed in three of the four coffee crops; one crop without traps was used as a control. Holes drilled into berries (%) were determined in these crops. There was a reduction in drilled berries in crops with traps, from the 2007/2008 harvest to the 2008/2009 harvest. The highest coffee berry borer densities in traps was observed in the flowering and small‑green berries stages. The red PET‑bottle trap is efficient in the mass control of the coffee berry borer population, since it reduces the percentage of drilled berries in 57%; however, this reduction is not enough to keep borer densities below the control level.O objetivo deste trabalho foi avaliar a eficácia de armadilha de garrafa Pet vermelha contendo compostos voláteis alcoólicos atrativos, no controle massal da broca‑do‑café (Hypothenemus hampei). As avaliações foram realizadas em quatro lavouras de café, durante dois anos. Foram distribuídas 900 armadilhas de garrafa Pet, pintadas de vermelho, em três das quatro lavouras; uma lavoura sem armadilhas foi usada como controle. O broqueamento dos frutos (%) foi determinado nessas lavouras. Houve redução do broqueamento de frutos nas lavouras com armadilhas, da safra 2007/2008 para a safra 2008/2009. As maiores densidades da broca‑do‑café nas armadilhas foram observadas nos estádios de floração e de frutos chumbinho. A armadilha de garrafa Pet vermelha é eficaz no controle massal da população da broca‑do‑café, por reduzir a percentagem de frutos broqueados em 57%; entretanto, essa redução não é suficiente para manter as densidades da broca abaixo do nível de controle

Ecological risks of biological control agents: impacts on IPM

Since the early days of integrated pest management a sound ecological foundation has been considered essential for the development of effective systems. From time to time, there have been attempts to evaluate the ways in which ecological theory is exploited in pest control, and to review the lessons that ecologists learn from pest management. In the last 20 years there have been many developments within the contribution of ecological theory to integrated pest management, and the objective of this book is to capture some of the new themes in both pest management and ecology that have emerged and to provide an updated assessment of the role that basic ecology plays in the development of rational and sustainable pest management practices. The major themes are examined, assessing the significance and potential impact of recent technological and conceptual developments for the future of integrated pest management
