“…Adding ethyl acetate, sugar cane, and the aggregation of pheromone in traps exposed for three months had a significant effect on R. palmarum capture, demonstrating the synergy between the pheromone and other attractive substances. A similar synergism exists associating three days of pre-fermented baits for the attractiveness of R. palmarum [65,68]. The experiences are contradictory but suggest exploring the attractive potential of semiochemicals originating from fermenting plant material.…”

Coupling several natural and synthetic lures with aggregation pheromones from the palm weevils Rhynchophorus palmarum and R. ferrugineus reveals a synergy that results in an increase in pest captures. The combined attraction of pure pheromones, ethyl acetate, and decaying sweet and starchy plant tissue increases the net total of mass-trapped weevils. The 2018 entrance of the red palm weevil (RPW) into South America has threatened palm-product income in Brazil and other neighboring countries. The presence of the new A1 quarantine pest necessitates the review of all available options for a sustainable mass-trapping, monitoring, and control strategy to ultimately target both weevils with the same device. The effective lure-blend set for the mass-trapping system will attract weevils in baiting and contaminating stations for entomopathogenic fungi that the same weevils will spread.

“…Adults can fly up to 1.6 km per day [ 7 , 8 ], but it is not common to see them flying during the hottest hours of the day. Experience suggests that R. palmarum populations fluctuate in economic palm-intensive cultivation [ 64 , 65 , 66 ].…”

“…Tómese en cuenta que las prácticas inadecuadas de uso sin control de insecticidas en las comunidades productivas de Kukra Hill son un potencial factor para el establecimiento de poblaciones insectiles con mayores niveles de tolerancia a los pesticidas, incrementando de esta forma los costos de manejo y los riesgos laborales y ambientales (Flores-Pacheco, Mairena, & Espluga, 2013). En todo caso, la estrategia de control debe dirigirse a la reducción de poblaciones de adultos de R. palmarum, basado en que éstos poseen mayor movilidad y rango de dispersión, y sus larvas son de difícil manejo al estar en el interior de la palma, antes de emerger como adultos maduros (Landero-Torres et al, 2015).…”

La enfermedad del anillo rojo causada por el nematodo Bursaphelenchus (Rhadinaphelenchus) cocophilus y transmitida por el picudo americano de las palmas, Rhynchophorus palmarum, ha sido considerada la enfermedad más importante del cocotero y la palma aceitera en América tropical, y todavía hoy es común en algunas plantaciones. El progreso de los síntomas puede ser muy rápido (forma aguda) y la palma afectada puede morir en unos pocos meses después de aparecer los primeros síntomas (amarillamiento progresivo y secamiento de las hojas empezando por las más viejas). En el otro extremo de un continuo de síntomas, las hojas más jóvenes emergen cortas y con varios tipos de malformaciones, pero las plantas pueden no morir en varios años (forma crónica). La presente investigación tiene como objetivo central analizar la dinámica poblacional del picudo de cocotero (Rhynchophorus palmarum) como vector de la enfermedad del anillo rojo; esta afección es causada por el nematodo Bursaphelenchus cocophilus, el cual se localiza en plantaciones de palma africana (Elaeis guianensis) localizadas en el municipio de Kukra Hill. Empleando dos tipos de trampas para la colecta de adultos de R. palmarum, y la cirugía para la extracción de su fase larvaria (esto combinado con el embudo de Baerman y el mapa de niveles críticos de la incidencia de este coleóptero), permitieron realizar el análisis epidemiológico en torno a la presencia de la enfermedad del anillo rojo ocasionada por R. cocophilus. No se encuentran pruebas estadísticas ni materiales (aislamiento del nematodo o presencia de plantas enfermas) que indiquen su presencia en las plantaciones de palma africana en Kukra Hill. Deben realizarse más estudios, durante más tiempo y con mayor número de repeticiones, para la corroboración y/o cambio en los hallazgos de este trabajo.

“…Additionally, further studies identified synergists to increase the capture efficiency of the traps (Oehlschlager, 2016; Rochat et al, 2000). Nevertheless, despite the negative economic impact that these weevil species have inflicted on palm plantations in the neotropics (including peach palm) and the convenience of having a reliable collection method, few studies have evaluated the spatiotemporal dynamics of these palm weevils (i.e., R. palmarum and D. borassi ), and all of them have focused only in R. palmarum populations (Dionisio et al, 2020; Landero‐Torres et al, 2015; Pinho et al, 2016; Santos et al, 2020).…”

The palm weevils Rhynchophorus palmarum and Dynamis borassi are prominent pest species in peach palms and coconut in Colombia. Nevertheless, knowledge of the population dynamics of these weevil species in the neotropical region is still scarce. In this study, we systematically sampled these weevils over 2 years using pheromone traps (1 trap ha−1) in an experimental peach palm plantation under heavy weevil infestation in southwestern Colombia. Additionally, we censused the palms in a portion of the plantation (a peach palm germplasm bank) before and after the weevil monitoring. We analysed the data to elucidate sex‐specific temporal and spatial patterns of both R. palmarum and D. borassi in a 19.13 ha area. Furthermore, we sought to detect peach palm landraces within the germplasm bank susceptible and resistant/tolerant to the weevil attack. During periods when insect populations were high, we observed that R. palmarum consistently outnumbered D. borassi. Specifically, we found that R. palmarum reached up to 80 insects trap−1 month−1, while D. borassi only reached around 30 insects trap−1 month−1 during the peak months. However, both species exhibited synchronous population peaks, which were not related to rainfall or temperature but rather to the phenological stage of the peach palm. Furthermore, the weevils had a highly aggregated spatial pattern; insect catchments were more prolific in areas where the landraces Nariño and Risaralda were sown. Moreover, the census evidenced that these two landraces were the most affected. Contrarily, weevil capture was overall low around the Guaviare landrace, this was the only landrace that exhibited an increase in stipes between census years. Our results highlight that complementary control strategies are needed to counteract sudden weevil population outbreaks, as pheromone traps are a good tool for monitoring but not for effective control. Furthermore, more importantly, a peach palm breeding programme based on the identified genotypes should be the basis for the integrated pest management of palm weevils.
