RNAi efficiency, systemic properties, and novel delivery methods for pest insect control : what we know so far [PDF]

, 2016
In recent years, the research on the potential of using RNA interference (RNAi) to suppress crop pests has made an outstanding growth. However, given the variability of RNAi efficiency that is observed in many insects, the development of novel approaches

[Biological characteristics of the egg phase of citrus root weevils].

Neotropical entomology, 2007
The goal of this work was to study some characteristics of the egg phase of three species of citrus root weevils. The insects were collected from citrus plants in Itapetininga, SP, and brought to the Laboratório de Biologia de Insetos of ESALQ/USP, in Piracicaba, SP, where the species Naupactus cervinus (Boheman), Naupactus versatilis (Hustache) and ...

Edge Effect on the Distribution of the Green Shield Bug Palomena prasina in Hazelnut Orchards, and the Role of Adjacent Habitats in Crop Colonization

Entomologia Experimentalis et Applicata, EarlyView.
Spring–Summer spatial dynamics of Palomena prasina (L.) and potential IPM strategies. ABSTRACT Palomena prasina (L.) (Hemiptera: Pentatomidae), the green shield bug (GSB), is an important hazelnut pest in Southern Europe. Currently, its control focuses on insecticide spraying during the crop season. We hypothesized that, as for other pentatomid species,

Ethnobotanical survey of pesticidal plants used in South Uganda : case study of Masaka district [PDF]

, 2011
Use of synthetic pesticides in developing countries is not only limited by their being expensive but also the small (uneconomic) fields whose limited production costs cannot offset costs of agricultural implements like agro-chemicals. Subsistence farmers,

Responses of Fruit Flies (Diptera: Tephritidae) to Protein Bait Applied at Different Densities

Journal of Applied Entomology, EarlyView.
ABSTRACT The effectiveness of odour‐based lures for insects is related to their active space, the air volume around an odour source in which an insect will detect and move towards it. This principle applies to protein baits laced with toxicants that are used as either sprays or stations to suppress pest fruit fly populations.
