“…In the adult stage, R. palmarum is attracted to the fermentation of exposed tissues, such as wounds or cuts on the leaves or palms diseased with BR. If the adult is contaminated, it can inoculate and infect the palm by feeding on or ovipositing in these tissues [21].…”

The red palm weevil (RPW) poses a significant threat to date palm ecosystems, highlighting the necessity of sustainable pest management strategies that carefully consider the delicate ecological balance within these environments. This comprehensive review delves into innovative approaches to sustainable pest management, specifically focusing on date palm, and seeks to unravel the intricate ecological dynamics underlying RPW infestations. We thoroughly analyze biocontrol methods, eco-friendly chemical interventions, and integrated pest management (IPM) strategies, aiming to minimize the ecological impact while effectively addressing RPW infestations. By emphasizing the interplay of both living organisms (biotic) and environmental factors (abiotic) in shaping RPW dynamics, we advocate for a holistic and sustainable management approach that ensures the long-term resilience of date palm ecosystems. This review aims to contribute to an ecologically sound framework for pest management, promoting the sustainability and vitality of date palm ecosystems amidst the challenges posed by the RPW.

Introduction: Rhynchophorus palmarum L. is the most destructive pest in Cocos nucifera plantations in Mexico. Objective: To estimate the cost-benefit of collecting R. palmarum by trapping in two coconut genotypes and to determine the correlation of trapping with environmental factors. Materials and methods: R. palmarum insects were captured on the genotypes ‘Alto Pacífico ecotipo 2’ (AP) and ‘Enano-Verde de Brasil’ (EVB) for one year. Five types of traps were used (BT = bucket type, TCT = trash can type, GT = gallon type, CSAT = Colegio Superior de Agricultura Tropical, BT = bottle type). Trapping was counted weekly, and the cost-benefit of trapping was determined. Trapping was analyzed with quasi-Poisson distribution, deviancy analysis and least significant difference. Trapping correlation with climate variables was determined with the Spearman’s coefficient. Results and discussion: A total of 3 414 insects were captured in AP. TCT and CSAT were the most effective (P < 0.014) with 40.3 % and 32.7 % of the total adults, respectively; they also had the best cost-benefit, 4.3 MXN and 5.5 MXN per insect, respectively. In EVB, 3.56 times more insects were captured (4 799) compared to AP with a 29.6:6.4 ratio, using GT. In both orchards, the correlations of climate variables with trapping were weak (less than 50 %); relative humidity was the most highly correlated, but negative. Conclusions: The efficiency of traps and their cost-benefit will allow growers to determine which trap to use for mechanical and ethological (aggregation pheromone) control of R. palmarum

Context The recent phytosanitary crisis caused by the stem borer weevils Dynamis borassi and Rhynchophorus palmarum in peach palms (Bactris gasipaes) seriously affected the economy of local families in Colombia. To understand the possible ecological mechanisms favoring the pest, the weevil-palm system needs to be studied from a multi-scale perspective. Objectives We evaluated the combined effects of agricultural management, landscape, topography, soil, and climate variables on infestation levels of peach palm caused by the weevils D. borassi and R. palmarumin the Colombian southwest to understand underlying ecological drivers of the current phytosanitary crisis. Methods The palm infestation levels (response variable) and local agronomic practices were recorded in 32 sites across Colombia's Pacific, Andes, and Amazon natural regions. For each peach palm crop, landscape variables were estimated from classified Sentinel-2 images, soil variables were extracted from the Soil Grids 250 m database, and climate variables were extracted from the CHIRPS and CHIRTS databases. Explanatory variables were analyzed using Generalized Linear Models and Partial Least Squares-Generalized Linear Models. Results Landscape variables, specifically the number and shape of non-forest patches, had a greater influence on peach palm infestation levels than other environmental variables, possibly related to the decrease in the density of Oenocarpus batatua, the natural palm host for D. borassi, leading it to switch to the peach palm. Conclusions A multi-scale approach of the weevil-palm interaction enabled us to identify an ecological mechanism that has not been proposed before. Our recommendation for families depending on the palm is to design palm management with a landscape perspective that considers the conservation of alternative hosts for the weevils in agroforestal plots.
