“…Previous observations in the region suggested that survival of Q. costaricenses is often determined by herbivory (Calderón‐Sanou et al 2019). Similarly, the good survival of P. caerulea above its natural range may reflect an absence of specialized herbivores, such as the avocado moth ( Stenoma catenifer ; Luna et al 2017), though at these elevations the seedlings grow slowly. Such increases in survival despite the slow growth accord with the life‐history tradeoffs expected to sort species along a competition gradient, suggesting that not just growth and competition, but also herbivory, and the resulting mortality, are important in determining observed distributions (Keddy and MacLellan 1990, Sheil 2016).…”

In theory, canopy openings can influence tree species establishment and resulting distributions over environmental gradients, but evidence concerning the magnitude and direction of such effects remain scarce. In this study we examine how canopy openings influence seedling persistence and growth and resulting elevation range limits. We transplanted 1360 seedlings of eight woody species (trees Trichilia habanensis, Persea caerulea, Cedrela tonduzii, Cornus disciflora, Quercus salicifolia, Q. bumelioides, Q. costaricensis and the shrub Hypericum irazuense) under the forest canopy and in open areas with understorey vegetation removed in a replicated design along a 2900 m elevation gradient in Costa Rica. We recorded survival, stem diameter and height over 18 months. We used hierarchical generalized additive models to examine relationships of seedling survival and growth with elevation and treatment (inside forest versus open area). We found a clear effect of open versus forest conditions on survival across the elevation gradient for six species. Species planted into open areas with full light exposure survived 100–1000 m below (~ 0.5–5°C warmer), and in one case 300 m above (~ 1.8°C colder) their observed ranges. Above 2900 m, survival of all species was markedly greater under the forest canopy versus open sites, suggesting facilitation from the forest, as frost occurred in open areas above this elevation. The resulting upper range increased between 200 and 1160 m (~ 1–6°C colder) compared to their observed range. At lower elevations, severe insect herbivory occurred on some species likely influencing lower range limits. Open areas influenced how seedling survival and growth varied with elevation for all the studied species. All species survived and grew outside the elevation ranges where they are typically observed. We suggest that the influence of forest gaps and clearings over extended gradients offers novel insights into tree range dynamics, limits and conservation.

“…Climatic variations can directly or inversely affect the proliferation of crop pests. Luna et al contributed to developing pest risk assessments for fruit growing by determining the geographic distribution of five important avocado insect pests located in Mexico (Conotrachelus aguacatae, Conotrachelus perseae, Heilipus lauri, Copturus aguacatae, Stenoma catenifer) and how these pests interact with commercial avocado growing areas [54]. To accomplish this, the study employed the maximum entropy method (MaxEnt) [55] to evaluate the impact of bioclimatic factors on the propagation of these pests.…”

Avocado is one of the most commercialized and profitable fruits in the international market. Its cultivation and production are centered in countries characterized by tropical and subtropical climatic conditions, many of them with emerging economies. Moreover, the use of technology is key to agricultural production improvement strategies. Using avocado crop data to forecast the potential impacts of biotic and abiotic factors, combined with smart farming technologies, growers can apply measures during a single production phase to reduce the risks caused by pests and weather variations. Therefore, this paper aims to distinguish the most relevant variables related to agroclimatic and phytosanitary events in avocado crops, their incidence on production and risk management, as well as the emerging technologies used for the identification and analysis of pests and diseases in avocados. A scientific literature search was performed, and the first search found 608 studies, and once the screening process was applied, 37 papers were included in this review. In the results, three research questions were answered that described the pests and diseases with high impact on avocado production, along with the data sources and the principal enabling technologies used in the identification of agroclimatic and phytosanitary events in avocados. Some challenges and trends in the parameterization of the technology in field conditions for data collection are also highlighted.

“…El cultivo de aguacate es afectado por diferentes plagas y enfermedades (Wysoki et al, 2002) por lo que se han desarrollado estrategias para el manejo integrado de las mismas, entre las que destaca el control biológico con HE. Algunas de las principales plagas del cultivo del aguacate son los trips de la especie Frankliniella occidentalis (Pergande) (Thysanoptera) (Maldonado-Zamora et al, 2016); los coleópteros Heilipus lauri Boheman, Conotrachelus aguacatae Barber, C. perseae Barber y Copturus aguacatae Kissinger, todos ellos barrenadores de la semilla, tronco y ramas del aguacate; el lepidóptero, Stenoma catenifer Walsingham barrenador de la semilla del aguacate (Luna et al, 2017); y potencialmente las plagas reglamentadas de escarabajos ambrosiales, Euwallacea fornicatus (Eichhoff) (Coleoptera: Curculionidae) (García-Avila et al, 2016) y Xyleborus glabratus Eichhoff (Carrillo et al, 2015). Recientemente en un estudio realizado en huertos comerciales de aguacate con presencia de C. aguacatae en el estado de Nayarit, México, se obtuvieron aislados de los hongos entomopatógenos Metarhizium pingshaense (Q. T. Chen y H. L. Guo) y M. anisopliae (Metsch) Sorokin, además, del hongo Beauveria bassiana (Bals.)…”

Background: Entomopathogenic fungi (EF) play a key role in the regulation of arthropod populations and biotransformation in natural systems, as well as biological pest control agents in different agroecosystems, including avocado cultivation (Persea americana Mill.), where Mexico is a leader in production and export worldwide. Objective: Determine the presence of EF in soil in commercial avocado orchards in the state of Colima, Mexico. Methodology: Sampling was carried out in three avocado orchards (Piedra rajada, El Guardián, and Montitlán) located in Comala and Cuauhtémoc in the state of Colima, Mexico, from July 2016 to June 2017. Soil samples were collected around avocado trees. Isolation of entomopathogenic fungi was performed using the Galleria mellonella Linnaeus insect trap technique. The isolates were identified considering their micro- and macroscopic characteristics with the taxonomic keys of Humber (2012). Results: A total of 108 samples were collected, of those, 120 isolates were obtained, of which 112 belong to the genus Metarhizium and eight to Beauveria. Implications: The recovered fungi have a great value for the avocado-growing areas of the state of Colima, either for the conservation of natural enemies of soil pests or for their potential use as an alternative to synthetic insecticides. Conclusion: Knowing the native micro-biota of the soil should be considered within biological pest control strategies, since it allows selecting the best adapted species, and including sustainable alternatives for the environment.
