ABSTRACT: Organic agriculture is distinguished by practices that benefit the environment and support sustainable agriculture. In the present study, leafy kale, Brassica oleracea L. var. acephala DC., was submitted to chemical and organic (castor bean cake and bovine manure) fertilization treatments aiming to verify the influence of these fertilizers on the occurrence of insect pests and natural enemies. The insects were sampled by visual examination of plants and pitfall traps. Brevicoryne brassicae (L.) and Myzus persicae (Sulzer) (Hemiptera: Aphididae) were the phytophagous insects that occurred more significantly in kale, under chemical rather than organic fertilization, whereas Harmonia axyridis (Pallas), Hippodamia convergens (Guérin-Méneville) (Coleoptera: Coccinellidae), Diaeretiella rapae (M’Intosh) (Hymenoptera: Braconidae) and spiders (Arachnida: Araneae) were abundant in kale under organic fertilizer. The study showed that castor bean cake and bovine manure as leafy kale fertilizers can reduce the use of insecticides and provide quality food.

And Control

O açaizeiro (Euterpe oleracea Martius) é uma palmeira nativa da várzea da região amazônica e pode ser indicada como a espécie de maior valor econômico do gênero. Dos seus frutos é extraída a polpa, largamente consumida, de variadas formas, pela população da região Norte do Brasil. Com a expansão da área plantada, muitos fatores podem comprometer a produção e limitar o cultivo, destacando-se a ocorrência de insetos-praga que causam prejuízos à produção. Este relato configura o primeiro registro de ocorrência da cigarrinha Aetalion reticulatum (Hemiptera: Auchenorrhyncha: Aethalionidae) em plantas de E. oleracea. A ocorrência deste inseto associado ao açaizeiro, em Rio Branco, Acre, aumenta a lista de hospedeiros desta cigarrinha no Brasil e reforça a necessidade de estudos de dinâmica populacional, levantamento de inimigos naturais, níveis de dano e métodos de controle, a fim de antecipar possíveis surtos populacionais desta praga em plantios comerciais de açaí no Estado. Infestation of Aetalion reticulatum (Linnaeus) (Hemiptera: Aethalionidae) in Plants of Euterpe oleracea Martius (Arecaceae) in Acre State, Brazil Abstract. The açai palm (Euterpe oleracea Martius) is a native palm tree from the Amazon region floodplains and may be indicated as the most economically profitable species of this genus. Its fruit pulp is extracted and widely consumed by the population of northern Brazil in several ways. With the expansion of the planted area many factors may affect the production and limit the cultivation, highlighting the occurrence of insect pests that cause losses in production. This report presents the first occurrence of the leafhopper Aetalion reticulatum (Linnaeus) (Hemiptera: Auchenorrhyncha: Aethalionidae) in E. oleracea plants. The occurrence of this insect associated with açai palms in Rio Branco, Acre, increases the list of hosts for this leafhopper in Brazil and reinforces the need for studies of population dynamics, survey of natural enemies, levels of damage and control methods in order to anticipate population outbreaks of this pest in commercial plantations of açai palms in the State.

Harlequin Ladybird

The harlequin ladybird, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), is a generalist predator and an effective biocontrol agent of various insect pests that has been exploited for the control of aphid pests in the greenhouse and field. However, insecticides are widely used to control aphid pests worldwide and the potential non-target effects of sulfoxaflor and imidacloprid for controlling aphid pests towards this biocontrol agent are little known. Although both sulfoxaflor and imidacloprid act on nicotinic acetylcholine receptors of insects, sulfoxaflor has a novel chemical structure compared with neonicotinoids. We assessed the lethal, sublethal and transgenerational effects of sulfoxaflor and imidacloprid on H. axyridis simultaneously exposed via ingestion of contaminated prey and via residual contact on the host plant at LC20 and LC50 doses estimated for the cotton aphid. Imidacloprid significantly reduced the survival of H. axyridis adults compared to sulfoxaflor at the same lethal concentration against cotton aphid. Both concentrations of imidacloprid and sulfoxaflor reduced the proportion of ovipositing females, and both concentrations of imidacloprid and sulfoxaflor, except LC20 dose of sulfoxaflor, reduced the fecundity and fertility of the parental generation. In the progeny of imidacloprid- and sulfoxaflor-exposed parents, both tested LC50 concentrations significantly decreased the juvenile survival rate, and both concentrations of imidacloprid and sulfoxaflor, except LC20 dose of sulfoxaflor, prolonged the development time. Our findings provide evidence of the negative influence of imidacloprid and sulfoxaflor at low lethal concentrations on the harlequin ladybird and on the progeny of exposed individuals, i.e., transgenerational effects. Hence, these findings stress the importance of optimizing the applications of imidacloprid and sulfoxaflor for the control of aphid pests, aiming at preserving the biocontrol services provided by H. axyridis throughout the integrated pest management approach.

Effective control of erratic crop pests requires accurate timing of treatments, and the dynamics of insect populations are inadequately understood. Aerial monitoring for many species simultaneously, instead of sampling each crop separately, enables the Rothamsted Insect Survey to provide accurate, quantitative, synoptic information on current levels of pest populations; this gives continuity to local assessment for advisory purposes, and adds a spatial dimension to population dynamics.

Resumo. Uma análise sobre a flutuação populacional da entomofauna associada a culturas de interesse econômico pode fornecer subsídios para o manejo integrado de pragas. Dentre os grupos economicamente relevantes podemos citar os coccinelídeos, conhecidos por serem predadores naturais de pragas agrícolas como afídeos. O presente trabalho se faz necessário visto que os Campos Gerais ainda carecem de dados sobre Coccinellidae relacionados a pomares de árvores frutíferas. O estudo foi realizado no pomar do Colégio Agrícola Estadual Augusto Ribas (Ponta Grossa-PR) de julho de 2004 a junho de 2006. As coletas foram feitas usando cada espécie do pomar, sendo elas agrupadas em dois grupos: cítricas e decíduas. Harmonia axyridis (Pallas) foi a espécie mais representativa na amostragem, compreendendo 38,35 % das coletas. as árvores cítricas apresentaram o maior número de insetos totalizando 82,19% da amostragem. É pertinente sugerir que a presença da H. axyridis pode ter afetado a diversidade da comunidade local, sendo ela uma espécie invasora e considerada uma melhor competidora. As árvores cítricas se apresentaram como as mais diversas. Podemos atribuir essa distribuição a maior presença de afídeos nas árvores cítricas, que foram atraídos pelos óleos voláteis secretados por essas plantas. No período final da amostragem houve uma queda populacional, que pode ser atribuída a condições climáticas desfavoráveis, e consequente redução a abundância dos afídeos presa e dos próprios coccinelídeos. Uma maior quantidade de recursos de presa permitiria que mais espécies de joaninhas coexistissem sem competir fortemente. Uma pesquisa futura poderia comparar situação da comunidade, analisando a influência da H. axyridis nas espécies locais.Diversity and seasonality of coccinellids (Coleoptera: Coccinellidae) in an orchard in the city of Ponta Grossa, ParanáAbstract. An analysis of the population fluctuation of entomofauna associated with crops of economic interest can provide subsidies for integrated pest management. Among the economically relevant groups we can mention the Coccinellidae, known to include natural predators of agricultural pests such as aphids. The present work is necessary since Parana's Campos Gerais still lack data on Coccinellidae related to orchards of fruit trees. The study was conducted in the orchard of Augusto Ribas State Agricultural College (Ponta Grossa-PR) from July 2004 to June 2006. Samples were collected from each species of the orchard, grouped into two groups: citrus and deciduous. Harmonia axyridis (Pallas) was the most representative species in the sample, comprising 38.35% of the collections. Citrus trees had the highest number of insects totaling 82.19% of the sample. It is pertinent to suggest that the presence of H. axyridis may have affected the diversity of the local community, being an invasive species and considered a better competitor. The citrus trees presented themselves as the most diverse. We can attribute this contribution to the greater presence of aphids in the citrus trees, which were attracted by the volatile oils secreted by these plants. In the final period of sampling there was a decrease in population size, which can be attributed to unfavorable climatic conditions, and consequent reduction in the abundance of prey aphids and of the coccinellids themselves. A greater amount of prey resources would allow more species of ladybugs to coexist without competing strongly. A future research could compare community situation by analyzing the influence of H. axyridis on local species.
