Spatial Analysis of Presence, Injury, and Economic Impact of the Melolonthidae (Coleoptera: Scarabaeoidea) Complex in Avocado Crops
Beetle insect species classified within the Melolonthidae complex (Coleoptera: Scarabaeoidea) are a serious pest in several crops around the world including avocado (Persea americana Mill). The present work focused on determining the spatial behavior of the Melolonthidae complex of beetles and determined the economic impact in avocado crops in Antioquia, Colombia, South America. Beetle presence and damage produced in both foliage and fruits were quantified during 3 years for each avocado tree tested
Socio-economic and technological typology of avocado cv. Hass farms from Antioquia (Colombia)
A typology of avocado cv. Hass farms was constructed based on information collected from productive units in Antioquia, Colombia. The study aimed to provide key information about the farms for those involved in the design of programs and public policies directed to growers. The data were scrutinized through Multiple Correspondence Analysis (MCA) and Cluster Analysis. The sample was made up of 214 growers of the crop. Quantitative and qualitative variables were employed for the MCA, which rendered
Avocado cv. Hass Needs Water Irrigation in Tropical Precipitation Regime: Evidence from Colombia
The primary natural source of water for the Hass avocado crop in the tropics is precipitation. However, this is insufficient to provide most crops’ water requirements due to the spatial and temporal variability. This study aims to demonstrate that Hass avocado requires irrigation in Colombia, and this is done by analyzing the dynamics of local precipitation regimes and the influence of Intertropical Convergence Zone phenomena (ITCZ) on the irrigation requirement (IR). This study was carried out
Surface soil water content as an indicator of Hass avocado irrigation scheduling
This study aims to determine whether Hass avocado irrigation can be triggered based on the surface soil water content (SSWC). To address this question, the soil water dynamics from three Hass avocado orchard plots located in Valle del Cauca (Colombia) was simulated using a model provided by Hydrus-1D software, which was calibrated through the genetic algorithm NSGA-II and validated using the soil matric potential measured at several depths at nine monitoring stations installed in the three plots.
Resource use and GHG emissions of eight tropical fruitspecies cultivated in Colombia
The cultivation of high-value fruit species is a profitable agricultural activity in many tropical countries; however, intensive fruit cultivation may depend on high amounts of external inputs. The objective of our study was to quantify and compare the resource use during the cultivation of eight tropical fruit species (Rubus glaucus, Solanum quitoense, Passiflora edulis, Cyphomandra betacea, Physalis peruviana, Ananas comosus, Persea americana and Mangifera indica) commonly cultivated in Colombia.
Economic Economic impact of the avocado (cv. Hass) wilt disease complex in Antioquia, Colombia, crops under different technological management levels
The avocado wilt disease complex is the most important pathology in avocado crops worldwide. Despite its importance, research about its economic losses is limited. In this work, the objective was to determine the economic impact of the wilt disease in three regions located in Antioquia, Colombia, and its relationship with the technological level of farm management. Six nurseries and 20 fruit production lots were tested for economic losses due to the wilt disease, including all crops stages of development.
