Abstract:
Harmonia axyridis has been used as an efficient biological control agent worldwide but is causing concern because of adverse impact on native species biodiversity predominantly through intra-guild predation and competition. There is thus a need to understand the ecological, biological and physiological factors that primarily contributed to the accelerated invasiveness and establishment of this species over a wide range of agricultural systems. The main focus of this project was to investigate various life-history traits and their interaction with external environments cues. The first part of t

Abstract:
Aphidophagous lady beetles rely on multiple sources of food in their environment. Alfalfa fields provide both aphids and many alternate foods, such as other arthropod prey, pollen, and fungi. Alfalfa fields (Medicago sativa L.) in Utah have low aphid densities, which may require lady beetles to consume alternative sources of food. Many methods can be used to determine these diets; frass analysis is used here to compare the diets of the introduced species Coccinella septempunctata L. with two native species, C. transversoguttata richardsoni Brown and Hippodamia convergens Guérin-Méneville, that

Abstract:
Resumo: A Espectroscopia do Infravermelho Próximo (NIRS) é uma técnica que analisa a composição molecular mediante a reflexão da luz no infravermelho (12500 cm-1 a 4000 cm-1) do espectro eletromagnético). Na metabolômica pode ser utilizada como uma ferramenta rápida e não invasiva capaz de diferenciar organismos pelo perfil metabólico. Aqui, esta técnica detectou a predação intraguilda (IGP) pela análise de conteúdo intestinal e fecal do predador Harmonia axyridis (Coleoptera: Coccinellidae). Exemplares de H. axyridis adultos de ambos os sexos foram alimentados com refeições contendo misturas

Des recherches sont entreprises à l'INRA sur la possibilité de contrôle biologique des populations de m. Persicae à l'aide d'une coccinelle prédatrice introduite, harmonia axyridis pallas. Nous analysons ici l'efficacité de h. Axyridis comme agent de lutte biologique contre m. Persicae, par la modélisation de l'interaction proie-prédateur en fonction de la température. Les données de base pour la caractérisation de ces interactions et l'élaboration d'un modèle de simulation sont établie

The palm is an important crop, primarily for its forage potential, being an alternative to feeding livestock is scarce native grasslands, especially during periods of prolonged drought. One of the main problems in the cultivation of cactus pear is the infestation of pests such as mealybug in scale, Diaspis echinocacti, when uncontrolled can cause severe yield losses, reaching 100%. The Integrated Management is an alternative to control this pest and maintenance of production out of economic damage. Therefore, this study aimed to evaluate the interaction between the spineless cactus, cochineal

This study investigated how the predicted increase in global temperature would affect the interaction between the cereal aphid, Sitobion avenae F. (Hemiptera: Aphididae), and its coccinellid predator, Coccinella septempunctata L. (Coleoptera: CoccinelIidae). A model describing the summer population dynamics of S. avenae (Carter et al., 1982) was modified and updated. New equations describing the dependence of aphid development and reproduction on temperature were formulated. A new submodel, describing the population dynamics of C. septempunctata, was incorporated into the model. The predatory

Abstract:
Native to Asia, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) is an invasive non-native ladybird in Europe and North America, where it was widely introduced as a biological control agent of aphids and coccids. There were three main objectives of this study: firstly, to investigate the spread and distribution of H. axyridis in Europe from the start of the invasion process; secondly, to study its ecology in Great Britain; and thirdly, to examine its effects on native ladybirds in Britain. In Europe, collaborations with a network of scientists allowed the collation of H. axyridis occurre

Abstract:
A necessidade por recursos alimentares move os insetos predadores na busca por presas, para garantir a sobrevivência. Existem vários fatores que podem influenciar o comportamento de busca e escolha por presas e, sob determinadas circunstâncias, o inseto pode escolher se alimentar de presas não alvo, como, por exemplo, inimigos naturais e assim prejudicar a população de organismos benéficos. Garantir a estabilidade do agroecossistema é uma forma de manter as populações de pragas em níveis compatíveis com a ação de inimigos naturais e, consequentemente obter o sucesso no controle biológico.
