Summary: Since its introduction to Hawaii in 2010, coffee berry borer (CBB) has caused significant economic damage to the coffee industry in the islands. We evaluated the economic benefits of managing CBB using three strategies: the use of the entomopathogenic fungus Beauveria bassiana alone, early integrated pest management (IPM), and research-based IPM. Our findings show that all types of management provided economic benefits, but research-based IPM had the greatest impact on coffee yield, price, and revenue. This highlights the importance of research and outreach in developing effective IPM strategies.

Summary: The coffee berry borer is the most important insect pest of coffee globally, causing significant crop losses due to its long life cycle inside the coffee berry. Utilizing a biological control method with entomopathogenic fungus sprayed on coffee berries effectively controls the borer, optimizing its application through mathematical modeling can maximize coffee yield and minimize control costs.

Summary: The study found that the flight activity of the coffee berry borer is significantly influenced by weather variables such as temperature, solar radiation, relative humidity, rainfall, and wind speed, showing clear seasonality. CBB flight activity is mainly concentrated within the temperature range of 20-26 degrees Celsius.

Summary: This review discusses the efforts made in Hawaii and Puerto Rico to develop an integrated pest management (IPM) program for coffee berry borer (CBB). Although the benefits of monitoring CBB activity have been proven, few growers in either region utilize traps or 30-tree sampling to inform their spray decisions. In Puerto Rico, farmers face a combination of factors, including other pests, diseases, and recurring hurricane damage, that prevent them from effectively managing CBB.

Summary: Ozone gas fumigation under vacuum was effective in controlling coffee berry borer and coffee leaf rust in green coffee without adverse effects on coffee quality. Adult coffee berry borers may be the key target for quarantine concerns.

Summary: Coffee is the second most economically important agricultural crop in Hawaii, but the introduction of coffee berry borer has posed a significant challenge to growers. This study found that frequent and efficient harvesting is an effective and economically viable alternative to frequent pesticide applications.

Summary: Swarm intelligence is used to simulate and explore different phenomena, with the development of a multiple swarm particles simulation algorithm (MSPSA) in this study. The MSPSA was specifically applied to simulate the proliferation of coffee berry borers in Colombian crops fields, providing a mathematical and statistical analysis of experimental results.

Summary: Beauveria bassiana (Bb) strain GHA is a major component of integrated pest management for coffee berry borer (CBB) in Hawai'i. Research showed that GHA spray can kill a certain percentage of CBB in commercial coffee fields, but cumulative mortality plateaued at a certain level even after multiple sprays, partly due to factors unrelated to efficacy. Recommendations for the use of Bb for CBB IPM were presented, highlighting that half rates of sprays were almost as effective as full rates.

Summary: The coffee berry borer is the most damaging pest to coffee crops. Chemical control methods have negative effects on the environment and non-target organisms, so a new caffeine-based insecticide has been developed. Laboratory and field tests showed that the caffeine-oleate formulation effectively killed coffee berry borers and other coffee pests without harming the coffee plants.

Summary: Understanding the reproduction dynamics of the coffee berry borer is crucial for pest management, a model tracking the infestation progress of coffee berries and the interaction with different populations of the pest was formulated. The stability analysis of the model suggests that control of the pest can be achieved over multiple seasons of coffee harvesting.

Summary: Vegetation connectivity is crucial for arboreal ants in coffee agroecosystems, influencing their activity, resource recruitment, and pest control ability. Naturally occurring vegetation connections have a greater impact on ant behavior and pest removal rates compared to artificial connectivity (string). Vegetation connectivity also buffers reductions in ant activity with increasing distance from the ant nest tree.

Summary: Coffee, the most popular beverage in the world, is primarily produced from two species - arabica and robusta. Arabica coffee, with lower productivity but better market price, faces threats from diseases, pests, and climate change. Plant biotechnology, including tissue culture and genetic transformation, can help address these challenges.

Summary: Coffee production is crucial for the economic growth of many countries, but the coffee berry borer poses a significant threat to global coffee production. This study presents a berry age-structured model to analyze the dynamics of coffee berry infestation by the coffee berry borer, and the theoretical results are validated through numerical simulations.
