Spatial distribution of beetle attack and its association with mango sudden decline: an investigation using geostatistical tools

Abstract

BACKGROUND: Ceratocystis fimbriata recognized among the species that induce mango sudden decline (MSD), causes plant death within a short period. The beetles Hypocryphalus mangiferae and Xyleborus affinis (Curculionidae: Scolytinae) are the vectors of MSD. Thorough understanding of the spatial distribution of the pest is crucial to designing control techniques and drawing up sampling plans. This study aimed to identify the beetles and their dispersal pattern in mango trees in MSD-infected commercial orchards, and the association with the severity of the C. fimbriata infestation. RESULTS: Beetle attacks were observed to be maximal on mango tree trunks revealing severe infestation. From the geostatistical analysis, an aggregated pattern was evident as galleries in the trunks and branches of mango trees.CONCLUSION: This is the first study to employ geostatic tools on a plant scale in MSD-infested mango orchards and to study the incidence of beetle attack. The results may prove a highly effective tool for mango growers, with respect to the management of beetles and MSD, as this will facilitate the monitoring of specific sites where the frequency of beetles and MSD is high.

Spatial and temporal patterns of rice planthopper populations in South and Southwest China

“…Many methodologies have been applied to describe the spatial and temporal patterns of pests. Among them, the most commonly used approaches are tracking the evolution of infestation distribution over time (Bayles et al, 2017;Cinnirella et al, 2020;Lausch et al, 2013;Ndjomatchoua et al, 2016;Reay-Jones et al, 2010), quantifying spatial autocorrelation (Blackshaw and Hicks, 2013;Bone et al, 2013;Cinnirella et al, 2020;Cocu et al, 2005;Smith et al, 2004;Ward et al, 2019), and employing geostatistical techniques (Pereira et al, 2019;Ribeiro et al, 2020;Rogers et al, 2015;Wright et al, 2002). Although above mentioned methodologies of spatial analysis have been applied to various types of insect pests and crops (Blackshaw and Hicks, 2013;Bone et al, 2013;Cinnirella et al, 2020;Cocu et al, 2005;Diaz et al, 2012;Lausch et al, 2013;Ndjomatchoua et al, 2016;Pereira et al, 2019;Reay-Jones et al, 2010;Ribeiro et al, 2020;Rogers et al, 2015;Smith et al, 2004;Ward et al, 2019;Wright et al, 2002), no studies have investigated the spatial and temporal patterns of RPH population using wide range data.…”

Temporal variation and spatial distribution of Euschistus heros (Hemiptera: Pentatomidae) during the soybean grain formation period

“…Furthermore, the use of geostatistics can be a complementary tool to graphically visualize how these insects are distributed in the field, providing useful visual information about the shape and location of the spatial distribution of pests under field conditions (Sciarretta & Trematerra, 2014). Therefore, knowledge of spatial distribution can be an important tool when associated with the integrated pest management to be considered when choosing to carry out chemical control of this insect, aiming at higher efficiency and reduction of control costs and damage to the environment (Pereira et al, 2018, Silva et al, 2021. In addition, little information can be found in the literature on the spatial distribution of E. heros during the soybean grain formation period.…”

“…Aliado ao MIP as geotecnologias tem sido inseridas como uma ferramenta que auxilia a tomada de decisão e são consideradas como uma técnica confiável pois incorpora as informações geográficas das amostras (SCIARRETTA; TREMATERRA, 2014;RIJAL et al, 2014). Pereira et al, (2018) destacam que a distribuição espacial das pragas Brazilian Journal of Development, Curitiba, v.7, n.1, p.4051-4065 jan. 2021 das culturas fornecem informações precisas sobre a localização de seus ataques mais frequentes nas plantações e sua dispersão. Estas informações podem melhorar a eficiência dos programas de manejo integrado de pragas (MIP) no tangente à amostragem e métodos de controle, especificamente para essas localidades (PEREIRA et al, 2018).…”
