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: 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: 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: 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: 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: 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: 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: This study investigated the effect of genetic diversity on the biocontrol potential of Beauveria bassiana on coffee berry borer. It was found that strains from Hawai'i Island and Puerto Rico had higher virulence than the commercial strain GHA due to their higher conidial densities. Additionally, CBB held on moist filter paper were more susceptible to infection, and several Hawaiian strains had higher conidial production than GHA. However, these strains took longer to initiate mass sporulation compared to GHA. Overall, the CP yields of several strains were comparable to or greater than GHA in terms of weight and conidial basis.

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: Macadamia nut is a significant edible crop in Hawaii, occupying a large amount of agricultural land. The study found that A. ironsidei infestation on macadamia trees can lead to yield loss, with varying impact on different varieties and environments, while kernel quality remains largely unaffected. Estimates of economic injury levels for A. ironsidei differ among varieties and environments, highlighting the need for tailored pest management strategies.

Summary: The structure of rhizosphere communities of two acacias is influenced by dispersal limitation between sites and local soil chemical conditions. Despite high taxonomic turnover in soils from different sites, their predicted functions are largely similar, indicating functional redundancy. Phylogenetically closely related plants may show remarkably similar selectivity for bacterial mutualists over vast geographic distances.

Summary: This study revealed that the Blackburn's sphinx moth experiences extremely low survival rates, primarily influenced by disappearance and predation, with the highest mortality rates observed during the egg stage. High apparent mortality rates were found across all developmental stages, indicating significant risks throughout the moth's pre-adult life cycle.

Summary: A new species, Phymastichus holoholo sp. nov., in the genus Phymastichus LaSalle (Hymenoptera: Eulophidae), is described as an endoparasitic species on adult Xyleborus beetles in Hawai`i. The host records, behavior, and potential use of this species as a biological control agent against Xyleborus beetles, particularly those implicated in spreading Rapid `Ohi`a Death, are discussed. The study also reports two instances of parasitism by the newly described species on beetles in the Euwallacea fornicatus species complex.
