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: Local isolates of the entomopathogenic fungus Beauveria bassiana in Puerto Rico show similar virulence as the commercial strain against the coffee berry borer in vitro, but one local isolate demonstrated better control in the field. Genetic structure of local Bb populations varies between fields and years, suggesting potential adaptation to the local environment. Commercial isolates may not be as successful in warm, humid coffee farm conditions compared to local isolates.

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 (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 investigates the genetic and phenotypic variation among different strains of Beauveria bassiana, an entomopathogenic fungus used for biological control of insect pests like the mountain pine beetle. The research identifies genes associated with virulence, mycotoxin synthesis, membrane transport, and transcription factors in more virulent strains. Differential expression of genes related to virulence, transmembrane transport, and stress response is observed, as well as upregulation of genes involved in oosporein biosynthesis. The findings provide a foundation for selecting or engineering the most effective B. bassiana strain for controlling insect pest populations.

Summary: This study evaluated the efficacy of the entomopathogenic nematode Steinernema carpocapsae and the entomopathogenic fungus Beauveria bassiana in managing stored-grain pests. Single application of S. carpocapsae caused higher mortality rates compared to B. bassiana for all six pest species. The combined treatment of EPF and EPN resulted in even higher mortality rates. The study demonstrates the potential of specific combinations of EPF and EPN as effective natural enemies against stored-grain pests.

Summary: Heavy metal exposure in the food chain enhances the susceptibility of Hyphantria cunea larvae to Beauveria bassiana. Cd exposure reduces cellular immunity and disrupts energy metabolism, making the larvae more vulnerable to Bb infection. The study highlights the importance of innate immunity and energy metabolism in determining the bio-control efficiency of entomopathogenic fungi in a Cd-polluted food chain.

Summary: Insect responses to chemical attractants are often measured using olfactory bioassays. This study compares the effectiveness of three common bioassay methods (Y-tube, small-cage arena, and rotating carousel field-cage) for measuring the attraction of Bactrocera dorsalis to methyl eugenol (ME). The results show that the rotating carousel field-cage and small-cage arena methods are effective at observing attraction to ME and detecting a significant reduction in ME response from ME-exposed males, while the Y-tube method is not suitable for this purpose.

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: 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.
