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: This study evaluates the drivers of the adoption and dis-adoption of Integrated Pest Management (IPM) practices in the suppression of mango fruit-fly infestation in Embu County, Kenya. It employs a Correlated Random Effects Probit Model and a Discrete-time Proportional Hazard Model on two-wave panel data of 149 mango farmers selected using a cluster sampling technique. The descriptive results show that 59% and 17% of the respondents were adopters and dis-adopters of mango fruit fly IPM practices, respectively. Empirical findings reveal that the cost of IPM and training on IPM positively and significantly influenced adoption, while the unavailability of the technology had a negative and significant effect on adoption. For dis-adoption, the results indicate that farm size and the quality of IPM positively influenced the hazard of exit from IPM use, and hence, enhanced the sustained adoption of IPM. The study recommends capacity building for mango farmers through training and increased access to extension services to enhance the adoption of this technology and prevent dis-adoption.

Summary: Synthetic mulches can provide warmth, moisture conservation, and weed prevention, but they can also be penetrated by soil-borne wireworms that target fruits such as tomato, cucurbit, and melon on the surface. Biodegradable mulch and polyethylene mulches of 0.9mil and 0.7mil thickness were easily penetrated by wireworms, while polyethylene mulches of 4mil and 6mil thickness significantly reduced penetration. The permeability of mulches indicated their attractiveness to the fruit-emitted carbon dioxide, while the impenetrability of woven fabric suggested physical exclusion.

Summary: A field experiment was conducted to investigate the effects of applying Biochar (BC) combined with chemical fertilization (CF) on coffee trees. The results showed that applying 8 or 16 t ha(-1) of BC reduced soil bulk density and increased soil aggregation status. The application of 16 t ha(-1) BC decreased exchangeable acidity by 60% and increased soil pH and organic carbon content. In both years, combining BC with 66% CF significantly increased soil respiration.

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: 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.
