Summary: The coffee berry borer (CBB) is a serious pest of coffee and management strategies need to focus on key developmental stages to effectively reduce population growth. The study compared CBB populations reared in the lab with those from the field, finding higher growth rates in the lab. Sensitivity analysis identified transitions from larva to pupa, pupa to juvenile, and adult female survival as key targets for CBB management. Effective management programs should target these vital rates to reduce population growth.

Summary: This study monitored the seasonal activity of the coffee berry borer on coffee farms in the high mountain and Blue Mountain regions of Jamaica. The highest infestation levels occurred in November and October in the respective regions, coinciding with susceptible berries. Rainfall was significantly correlated with CBB activity and infestation. This study lays the groundwork for understanding CBB population dynamics in Jamaica.

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: 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: Thirty-three fungi were isolated from coffee berry borer cadavers, and two fungal isolates, Bb-NCHU-271 and Bb-NCHU-272, showed effective insect-killing activity. Application of entomopathogenic fungi (EPF) before the infestation of coffee berry borers into coffee fruits enhanced the control effect.

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: The study annotated the chemosensory genes of the coffee berry borer using genome and transcriptome data, revealing an enrichment of gene expression in adults compared to larvae, suggesting a potential link to host-finding behavior. Additionally, male-specific genome content was identified, hinting at the involvement of a Y-like chromosome in the beetle's sex determination mechanism.

Summary: Before recommending insecticides for treating the coffee berry borer, it is important to understand their impact on adult insects, their repellency, and their effect on reproductive output. This study examined various experimental methods to assess the effects of different insecticides on the coffee berry borer under laboratory conditions. The study used disinfected green coffee fruits and CBB adults to evaluate the efficacy of the insecticides. It also investigated the infestation and survival of the CBB under controlled conditions. The results of this study provide valuable information for selecting insecticides to manage the coffee berry borer.

Summary: The study successfully obtained coffee plants with antibiosis against coffee berry borer through crossbreeding. The results showed that these plants exhibited a lower number of borer stages both in controlled conditions and field trials. Additionally, the study found that this antibiosis trait is associated with multiple genes.

Summary: Coffee leaf rust (CLR) is a highly damaging disease for the coffee industry globally. In Hawaii, CLR was first detected in 2020 and rapidly spread across the state. A monitoring program was initiated in Kona, West Hawaii Island, to track the spread of this invasive disease across different elevations. The study provides insights into CLR patterns and suggests improved fungicide coverage and timing are necessary to control the disease effectively.

Summary: Jackson traps baited with male lures with or without insecticides are essential for surveillance and monitoring against pest tephritid fruit flies. The efficiency of these traps depends on the combination of trap/lure/toxicant. The study found that plastic polymer plugs and pre-packaged DDVP strips can effectively replace the current liquid lure/naled combinations without affecting trap efficiency for eight weeks or longer. The 'high tack' adhesive did not show any advantage over the current standard, and the combination of lure + DDVP had different efficiencies for different fruit fly species.

Summary: Fruit flies, such as the melon fly, are major pests that affect horticulture globally. Understanding their movement is crucial for effective control strategies. This study used harmonic radar tagging to track individual fruit flies and found that they exhibited strong flight directional biases, possibly influenced by wind direction. Additionally, flight distances varied in different environments. These findings have important implications for improving pest control and modeling.

Summary: Typical delimitation trapping survey designs for insect populations often use regularly spaced grids, but other shapes have not been evaluated. This study investigated the use of transect-based designs, incorporating crossed, spoked, and parallel lines of traps, and compared them to a regular grid design. The results showed that transect-based designs can reduce servicing distances by 65-89% without compromising detection probabilities. This study suggests that trap-sect designs have the potential to reduce costs and increase flexibility in delimitation surveys.

Summary: Pest insect surveillance using lures is commonly used to support market access for traded articles, but less frequently used to provide confidence in pest freedom within registered trade sites. A simulation model was used to evaluate the effectiveness of site-based surveillance strategies in detecting pests originating from within or outside the site. The results showed that trap density and lure attractiveness were the primary factors affecting detection probability, and high detection probability could be achieved within 7 days using realistic values for these factors.

Summary: Tropical rainforest communities often have a small number of species-rich genera that contribute disproportionately to alpha diversity. This study focused on the assembly patterns of Cyrtandra species in the Pacific Basin and found that coexisting species have closer phylogenetic relationships and phenotypic similarities than expected by chance. The presence of phylogenetic signal in floral traits suggests that pollinators act as a filter, selecting for similar floral morphology among closely related species. Leaf size also contributes to niche clustering at different spatial scales. Overall, this study supports the idea that niche-based processes structure diversity in plant communities at regional and local scales.

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.
