Differential effects of ants as biological control of the coffee berry borer in Puerto Rico

چکیده
Conservation biological control consists of managing agroecosystem to maintain and enhance the action natural enemies. Agroforestry systems such as shaded coffee system has been shown high diversity organisms, including predators parasitoids insect pest. The berry borer (CBB), Hypothenemus hampei, is one most widely distributed pests frequently causing severe economic damage. Ants have reported enemies CBB, but different species ants are known sometime contrasting effects against CBB. In this study, we examine damage survival CBB on plants that dominated by six ants, Solenopsis invicta, Wasmannia auropunctata, Monomorium floricola, Paratrechina longicornis, Brachymyrmex heeri Pheidole moerens, in Puerto Rico. This represents a novel community since four non-native. We hypothesized large dominant species, S. would reduce preying adult outside berries, while smaller reproducing adults inside berries (and potentially also immature stages, although not quantified study). Results show invicta was associated with significantly reduced only W. whereas others were any effect survival. Surprisingly, P. moerens longicornis had significant positive suggesting these could forage did harbor or two aggressive both which negatively study suggests negative impact auropunctata indirectly facilitates protecting it from predation once gains entrance berry.

The presence of the coffee berry borer, Hypothenemus hampei, in Puerto Rico: fact or fiction?
The coffee berry borer, Hypothenemus hampei Ferrari (Coleoptera: Scolytidae), is widely considered to be the most devastating pest of coffee. Endemic to Central Africa, the coffee berry borer can now be found in most coffee growing regions throughout the world (Le Pelley 1968). Annual losses caused by this insect have been estimated at over $500 million annually (P. Baker, CABI Bioscience, UK; ...
متن کاملIntegrated Pest Management of Coffee Berry Borer in Hawaii and Puerto Rico: Current Status and Prospects
The coffee berry borer (CBB), Hypothenemus hampei, is the most significant insect pest of coffee worldwide. Since CBB was detected in Puerto Rico in 2007 and Hawaii in 2010, coffee growers from these islands are facing increased costs, reduced coffee quality, and increased pest management challenges. Here, we outline the CBB situation, and summarize the findings of growers, researchers, and ext...
متن کاملThe Coffee Berry Borer (Coleoptera: Curculionidae) in Puerto Rico: Distribution, Infestation, and Population per Fruit
The coffee berry borer (CBB) (Hypothenemus hampei: Ferrar) was first detected in Puerto Rico in 2007. Its distribution since then has been extensive, but not extensively documented. An island-wide survey was carried out from August to November 2014 (the coffee production season) to assess CBB distribution, infestation, and population per fruit. The CBB was well-established throughout the coffee...

The aim of this study was to evaluate the coffee germplasm of the Paraná Agronomic Institute (IAPAR) for resistance to the coffee-berry-borer. Preliminary field evaluation was performed in August 2004 and the fruits of less damaged genotypes in the field were evaluated under controlled condition with obligated and free choice experiments established in a randomized complete design with three re...
متن کاملTwig-Nesting Ants: The Hidden Predators of the Coffee Berry Borer in Chiapas, Mexico
Coffee is a globally important crop that is subject to numerous pest problems, many of which are partially controlled by predatory ants. Yet several studies have proposed that these ecosystem services may be reduced where agricultural systems are more intensively managed. Here we investigate the predatory ability of twignesting ants on the main pest of coffee, the coffee berry borer (Hypothenem...
