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: Studying the impact of predation on cryptic herbivorous insects is challenging due to their life cycle being mostly or entirely inside the host plant. In this study, 3D-printed artificial coffee berries were used to investigate the predation of coffee berry borers by flat bark beetles. The results, obtained through laboratory and field testing, demonstrated the effectiveness of 3D-printed materials in creating realistic models for studying predation.

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: 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 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: Some animals have evolved chemical weapons to deter predators, such as bombardier beetles that can eject toxic chemicals at high temperatures from their abdomens. Experimental results show that bombing is essential for Pheropsophus jessoensis to defend against praying mantises, enabling them to successfully deter mantises.

Summary: The study on Aedes albopictus microbiomes in O'ahu, Hawai'i, showed that the diversity of the mosquito microbiomes is associated with local climate and land-use patterns, primarily influenced by a landscape-scale moisture gradient. However, there was no evidence to support a link between mosquito microbiome diversity and urbanization.

Summary: Tephritid fruit flies are major pests for fruit production and global trade, with fruits categorized as natural hosts, conditional hosts, or nonhosts. The infestation rate varies for different host fruits, ranging from highly attractive to poor hosts. Postharvest treatments may still be required for fruits with low infestation rates to reduce the risk of exporting fruit flies.

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: The study found that avocados are generally poor hosts for Oriental fruit flies, suggesting the need for specific mitigation measures in export protocols. Field tests showed that mature hard fruit had lower infestation rates, indicating their low susceptibility to infestation. This suggests that a systems approach based on the poor host status, low prevalence, limited harvest period, and distribution area can be used for exporting 'Malama' avocados from Hawai'i to the continental United States.

Summary: The boll weevil, a historically impactful insect, nearly destroyed the US cotton industry in the early 20th century. Current management strategies using pheromone baited traps and insecticides are not sustainable, prompting the need for novel control methods. A high-quality genome assembly of the boll weevil was presented, providing valuable gene targets for future pest control. Transcriptome analysis identified potential genes and gene families for new control strategies.

Summary: Biological introductions serve as unintended natural experiments and provide unique insights into evolutionary processes. Invasive phytophagous insects, in particular, are important for studying adaptation as they often need to rapidly adapt to new host plants. However, the genetic paradox of invasions poses a limitation to the adaptive potential of invasive populations due to reduced genetic diversity. One potential solution to this paradox is the existence of multiple invasive waves that increase genetic variation in invasive populations.

Summary: Beverage mixtures based on pineapple and turmeric juice with different concentrations of turmeric were developed. The addition of turmeric resulted in increased physicochemical and nutritional properties, as well as the presence of specific volatile compounds. However, higher concentrations of turmeric negatively affected the overall flavor due to decreased palatability. The pineapple juice fortified with 10% turmeric showed the best overall quality, suggesting the potential for development as a commercial functional beverage.

Summary: The square-necked grain beetle, Cathartus quadricollis, is a predator of two significant crop pests in Hawaii, the coffee berry borer and the tropical nut borer. This study found that using a membrane-type quadrilure release dispenser and black sticky traps was the most effective way to attract C. quadricollis. Additionally, a breeding station was developed to multiply C. quadricollis numbers in the field, which could help with biological control of the coffee berry borer and tropical nut borer.

Summary: This study explored the effect of humidity-triggered controlled-release 1-methylcyclopropene (1-MCP) sheets on the postharvest quality of papaya fruit. The results showed that 1-MCP treatment inhibited fruit softening, reduced weight loss and peel color deterioration without causing any physiological disorders. The 1.0-2.0 ppm 1-MCP-treated fruit received the highest score for papaya flavor and sweetness respectively and the lowest score for off-flavor. The humidity-triggered controlled-release 1-MCP sheets are effective and convenient, and they can serve as an important tool for regulating postharvest papaya ripening with economic benefits.

Summary: In this study, the chromosome-level genome assembly of the small hive beetle (SHB) was completed for the first time. The features of SHB sex chromosomes and the asymmetry of the primary sex ratio were analyzed using this annotated assembly. The genome-enabled insights are critical for understanding the successful traits of SHB and determining the causes of observed sex ratio asymmetries.
