“…Henosepilachna vigintioctopunctata (Fabricius) (Coleoptera: Coccinellidae) is among the most serious insect pests in Asian countries (Araujo‐Siqueira & Almeida, 2004) such as China, India, Japan and Korea (Rajagopal & Trivedl, 1989; Zhou et al ., 2015; Wang et al ., 2017; Huang et al ., 2018; Zhang et al ., 2018). It also occurs in other countries outside Asia, for instance, Brazil (Araujo‐Siqueira & Almeida, 2004) and Australia (Richards & Filewood, 1988).…”

Henosepilachna vigintioctopunctata is a serious insect pest which attacks a large number of nightshades and cucurbits in Asian countries, Brazil and Australia. Prolonged application of traditional pesticides has caused environmental pollution and exerted deleterious effects on human health. Finding new approaches with high target specificity and low environmental contamination has become an urgent task. RNA interference (RNAi) induced by double-stranded RNA (dsRNA) is expected to be applicable to managing this pest. Here we evaluated the effects of Escherichia coli-expressed dsRNAs targeting ecdysone receptor (EcR) gene via dietary delivery in laboratory and foliar spraying in a greenhouse. The target transcript was successfully knocked down when the 4th-instar larvae had fed on potato foliage dipped with dsEcR in a laboratory bioassay. Around 85% of the HvEcR RNAi larvae remained as prepupae or became abnormal pupae, and failed to emerge into adults. Ingestion of dsEcR-immersed foliage by the 3rd-instar larvae effectuated a comparable RNAi response and brought about more severe defects: all the resultant larvae arrested development, remained as prepupae and finally died. For assay in the greenhouse, a dsEcR-contained E. coli suspension was directly sprayed to the foliage of greenhouse-growing potato plants and the 3rd-and 4th-instar larvae were transferred to the leaves. High RNAi efficacy was obtained and identical RNAi phenotypes were observed in treated larvae. In addition, spraying dsEcR reduced leaf damage. Our results indicate a possibility of practical application of dsEcR as an environmentally friendly RNA pesticide to control H. vigintioctopunctata larvae.

“…A espécie nativa da América do Norte, Epilachna borealis (Fabricius), é uma praga da cultura de abóbora e outras plantações associadas (Vandenberg 2002). Na região Sul do Brasil são relativamente comuns as espécies de Epilachna paenulata (Germar), Epilachna spreta (Mulsant) e Epilachna cacica (Guèrin), que usam como recurso alimentar folhas de espécies cultivadas em hortas como Curcubita pepo Linnaues (aboboreira), Sechium edule Sw (chuchuzeiro) e de Cucumis sativus Linnaeus (pepineiro) (Araújo-Siqueira & Almeida 2004). Na Rússia existem quatro espécies de filófagos: Henosepilachna vigintioctomaculata (Motschulsky), Subcoccinella vigintiquatuorpunctata (Linnaeus) e Epilachna chinensis (Weise), das quais a primeira é relatada como praga de batatas, pepinos e tomates (Kusnetsov 1997).…”

“…Essas espécies apresentam um comportamento muito interessante que é o de demarcar a região da folha aonde vão se alimentar, cortando com as mandíbulas cada um dos vasos que nutrem a planta. Nesse caso ocorre interrupção da condução da seiva, impedindo que haja uma reação da planta, introduzindo, por exemplo, uma substância tóxica no trato alimentar do inseto (Almeida & Marinoni 1986, Araújo-Siqueira & Almeida 2004, Almeida & Ribeiro-Costa 2009.…”

Este artigo busca organizar uma síntese sobre os hábitos e estratégias alimentares apresentadas pelos Coccinellidae. A família é heterogênea no que diz respeito ao comportamento alimentar, podendo ser dividida em três grupos principais de acordo com sua especialização: predadores, fitófagos e micófagos. Os coccinelídeos predadores são subdivididos de acordo com o status taxonômico das suas presas preferenciais: acarófagos, afidófagos e coccidófagos. Já os fitófagos são subdivididos em: filógafos, os quais se alimentam exclusivamente de folhas, hastes ou outras partes das plantas e polenófagos. A frugivoria em coccinelídeos parece ser rara, mas já foi documentada para algumas espécies. Tanto as larvas como os adultos dos coccinelídeos predadores podem consumir uma enorme gama de alimentos e muitas espécies são consideradas polífagas. A polifagia é geralmente observada como uma estratégia de emergência quando o alimento preferencial encontra-se escasso. Os coccinelídeos apresentam uma vasta gama de tipos de alimentos preferenciais, os quais abrangem diferentes reinos e níveis tróficos. O conhecimento dos hábitos alimentares, mesmo das espécies mais comuns, ainda é restrito, tornando uma tarefa difícil discutir as especializações alimentares de cada tribo. Vista a enorme gama de espécies com grande potencial para atuar como agentes de controle biológico, especialmente de pragas de importância agrícola, faz-se necessário intensificar os estudos relacionados à biologia, ao comportamento e à filogenia. Palavras-chave: fitófago; hábitos alimentares; micófago; predador. ABSTRACT FOOD PREFERENCE AND FEEDING STRATEGIES IN COCCINELLIDAE (COLEOPTERA). This article aims to organize a synthesis about the feeding preference and feeding strategies presented by the Coccinellidae. The family is heterogeneous with regard to eating behavior and it can be divided into three main groups: predators, phytophagous and mycophagous. The predators coccinellids are subdivided according to the taxonomic status of their preferred prey: mite feeders, aphidophagous and coccidophagous. The phytophagous are subdivided into: phyllophagous, which feed exclusively on leaves, stems or other plant parts and polenophagous. The frugivory in coccinellids appears to be rare, but has been documented for some species. Both larvae and adults of predators coccinellids can consume an enormous range of food and many species are considered polyphagous. The polyphagy is usually observed as an emergency strategy when the preferred food is scarce. The coccinellids exhibit a wide range of preferred food types, which cover different kingdoms and trophic levels. The knowledge of feeding habits, even of the most common species, is still restrict, making a difficult task to discuss the food specialties of each tribe. Due to the huge range of species with great potential to act as biological control agents, especially of pests of agricultural importance, it is necessary to intensify the studies related to biology, behavior and phylogeny.

Henosepilachna vigintioctopunctata (F.) is a serious pest of numerous solanaceous crops in many Asian countries. The purpose of this study was to clarify the effects of delayed mating on mating success, fecundity, fertility, pre-oviposition period, oviposition period, adult longevity, and population life table parameters (including net reproductive rate, intrinsic and finite rates of increase, doubling time, and mean generation time) of H. vigintioctopunctata. Beginning three days after emergence for both sexes, mating was delayed an additional 0, 2, 4, 6, or 8 days. We compared the data when mating was delayed for males only with the data when mating was similarly delayed for females only. Reproductive and life table parameters were calculated from the two data sets and compared. The results showed that the preoviposition and oviposition period of adults was significantly reduced by delayed mating, while the preoviposition period was not significantly different in adults mated at older ages. The mating success rate, fecundity, and proportion of hatching eggs decreased with increasing mating age. Longevity was not affected by the age at mating. Mating delay also affected the life table parameters of H. vigintioctopunctata, with a similar trend observed in the net reproductive rate and intrinsic and finite rates of increase, all of which decreased gradually as the number of delay days increased. The population doubling time increased with increases in mating age. The results also showed that delayed mating was an effective measure to consider in controlling H. vigintioctopunctata. It is hoped that our data will provide a scientific basis and contribute technical guidance for forecasting and integrated management of this pest.
