Henosepilachna vigintioctopunctata (Coleoptera: Coccinellidae: Epilachninae) Attacking Cultivated and Wild Crops in Brazil

Abstract

Henosepilachna vigintioctopunctata was recorded on Solanum melongena L. for the first time in cultivated crops areas in Espirito Santo State, southeastern Brazil, in the first semester of 2017. In one-year research, H. vigintioctopunctata was recorded in eight host plants of the families Amaranthaceae and Solanaceae. These new records represent a high potential establishment of this pest in Brazil.

“…O primeiro registro da espécie no país, foi realizado em 1990 na cidade de Curitiba, no estado do Paraná em uma região de cucurbitáceas não identificadas (AGUIAR et al, 2019). Em 1991, foi coletada em Paranaguá, em Piper nigrum L. (pimenta) (ARAUJO-SIQUEIRA; ALMEIDA, 2004) e em 1992, em Solanum americanum Mill.…”

“…(maria-preta), em Itajaí (SCHRODER et al, 1993). Nos três primeiros registros mencionados, apenas adultos foram relatados (AGUIAR et al, 2019).…”

Effects of Delayed Mating on the Reproductive Performance of Henosepilachna vigintioctopunctata (F.) (Coleoptera: Coccinellidae)

“…[5]. Initially, the newly hatched larvae aggregate mainly on the back of the leaves to feed on mesophyll [9]. In later instars, the damage they cause becomes serious, with the affected leaves usually forming irregular transparent spots or perforations, which eventually turn into brown concave spots [1,9,10].…”

“…Initially, the newly hatched larvae aggregate mainly on the back of the leaves to feed on mesophyll [9]. In later instars, the damage they cause becomes serious, with the affected leaves usually forming irregular transparent spots or perforations, which eventually turn into brown concave spots [1,9,10]. Young stems, petals, sepals, and fruits are also damaged by the larvae [10,11], resulting in a reduction in plant yield, poor fruit quality, and even plant death, all of which seriously affect the economic value of the affected crop [12][13][14][15].…”
