Screening of Coconut Genotypes Against Coconut Eriophyid Mite (Aceria guerreronis Keifer.)

Abstract

The coconut genotypes were screened for their level of susceptibility to coconut eriophyid mite. Based on the mean damage Grade Index score none of the coconut genotypes were found to be resistant to eriophyid mite. However the genotypes,

Towards the Understanding of Important Coconut Endosperm Phenotypes: Is there an Epigenetic Control?

“…The mite causes scarring in the growing nuts especially 2-3 months before maturation stage since the mite inhabits the basal portion of the nut below the perianth. Eriophyid mite infestation is prevalent in India [80]. Various reports have shown that the Lono cultivar ranges from susceptible [81] to moderately resistant [80] against the eriophyid mite (Aceria guerreronis Keifer), while the cultivar had been also shown to be 71% resistant, and is the second most resistant variety following the Chowghat Green Dwarf, against the root wilt disease [82].…”

Biomonitoring the <i>Vitex gardneriana</i> Shauer (Lamiaceae) Toxic Effects to Shed Light on Bioactive Compounds against a Major Coconut Pest Mite

“…The coconut mite Aceria guerreronis Keifer (Acari: Eriophyidae) is the most expressive pest to affect coconut plantations in tropical America, Asia, and Africa [12] [13] [14] [15]. A. guerreronis populations are found in restricted spaces under fruit bracts [16] [17].…”

“…The attack of this pest leads to premature fruit drop, reduced fruit size, weight and water volume. Aesthetic skin necrosis also reduces the value of fruits intended for the fresh market [12] [19].…”
