Annotation:

Les insectes herbivores ont développé des mécanismes de détoxication des toxines de plantes qu’ils ingèrent, notamment grâce à l’expression de cytochrome P450. Les P450 métabolisent les xénobiotiques, et chez les vertébrés, les récepteurs nucléaires qui contrôlent leur induction sont bien connus. Nous avons montré chez Drosophila que peu de P450 répondent aux xénobiotiques et que le CYP6A2 montre un pattern d’expression similaire au CYP2 chez les mammifères qui est induit par les récepteurs nucléaires CAR/PXR. Chez le ravageur polyphage Spodoptera frugiperda, nous avons réalisé une analyse tra

Annotation:

False codling moth (FCM), Thaumatotibia leucotreta is an extremely important pest of citrus in South Africa and with the shift away from the use of chemicals, alternate control options are needed. One avenue of control which has only recently been investigated against the soil-borne life stages of FCM is the use of entomopathogenic fungi (EPF). In 2009, 12 entomopathogenic fungal isolates collected from South African citrus orchards showed good control potential during laboratory conducted bioassays. The aim of this study was to further analyse the potential of these isolates through concentra

Control of the citrus pest, false codling moth (FCM), Thaumatotibia leucotreta Meyrick (Lepidoptera: Tortricidae) is crucial for the South African citrus industry. The economic losses and phytosanitary status of this pest, coupled with increased consumer awareness and demands, has created a need for effective, IPM-compatible control measures for use against the soil-dwelling life stages of FCM. Promising developments in the field of microbial control through the use of entomopathogenic fungi (EPF) and entomopathogenic nematodes (EPNs) have highlighted the need for research regarding pupation b

H. armigera larvae are a key stage for pest management in conmercial irrigated cotton crops in South Africa. Effective survey methods for detecting larval populations in the field require an understanding of the biology of the larvae, particularly their feeding habits. Their feeding is central to the development of pest threshold levels for the implementation of integrated control programmes. This applies to routine surveys for the larvae as well as to the damage they cause. Biological characteristics of the larvae are described with the emphasis on the identification of the larval instars, wh

Predictions for differences between constant and fluctuating thermal conditions were derived from Jensen’s inequality, and artificial diets of differing nutritional quality

Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) (African bollworm) is a typical noctuid with a very catholic taste in food plants and whose larvae feed on a wide range of cultivated and wild plants. It has been identified as the most polyphagous and injurious pest in South Africa. Helicoverpa armigera is also a key pest of cotton in many parts of the world. This key pest requires extensive control as it adversely effects yield and has built up resistance to synthetic pyrethroid insecticides. Cotton is an important crop produced by commercial and small-scale farmers in South Africa. The lo

The connection between variable synchrony of insect eclosion with host budburst and variability in insect densities was investigated. Experiments with gypsy moth (Lymantria dispar L.) larvae determined the duration of acceptable foliage after budbreak of nine hardwood species. Four competing conceptual models of environmental influences on the timing of budburst were compared and evaluated. The best budburst model was combined with an eclosion model to estimate the frequency of asynchrony and its correlation with density. Synchrony with budburst has a smaller effect than weather after hatch, o

O objetivo desse trabalho foi estudar atrativos adicionados a inseticidas e usados na forma de isca tóxica no controle dos adultos de Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) determinando as doses adequadas e distâncias de aplicação dessas iscas. Em laboratório, foram testadas diversas iscas, incluindo seletividade, idade e concentração das mesmas, escolha do inseticida e sua melhor dose, determinação da distância dentro da área de aplicação, efeito residual e atratividade a alguns inimigos naturais. A D. saccharalis foi mantida em condições controladas de temperatura (2

The study examined the larval parasitoids of Cryptophlebia leucotreta (Meyrick) on citrus in South Africa and aimed to improve the existing rearing techniques of C. leucotreta with a view to mass rearing of biological control agents. The biological characteristics of Agathis bishopi Nixon (Hymenoptera: Braconidae) were studied, with an emphasis on parasitism rates in the field, host stage preference, developmental rate, life span and offspring sex ratios. Two larval parasitoids, A. bishopi and Apophua leucotretae (Wilkinson) (Hymenoptera: Ichneumonidae), and an egg parasitoid, Trichogrammatoid

Annotation:

The false codling moth (FCM), Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae), is an important pest of citrus in South Africa and challenging to manage due to its inconspicuous nature. An effective method currently being employed for the area-wide suppression of the FCM is the Sterile Insect Technique (SIT) and the effective dispersal of sterile moths is very important for success with SIT. This study was conducted in the Addo area of the Sundays River Valley (Eastern Cape) where the programme is commercially used. In this study, sterile male moths were released in different orch

Chez les insectes phytophages, l'adaptation à la plante hôte peut correspondre à l'une des premières étapes de la spéciation. Dans ce contexte, ce manuscrit s'intéresse à Spodoptera frugiperda (Lepidoptera : Noctuidae), un ravageur responsable de dommages importants sur de nombreuses cultures en Amérique et dans les Caraïbes. Spodoptera frugiperda présente deux variants, l'un adapté au riz et l'autre au maïs, et constitue un modèle biologique pertinent pour étudier ce mécanisme. En effet, les deux variants sont morphologiquement identiques, mais ils sont génétiquement différenciés et présenten

Dichomeris famulata Meyrick, 1914 (Lepidoptera: Gelechiidae) é uma nova praga da espiga de milho no Brasil, sendo importante em áreas de produção de sementes porque os grãos atacados pelas lagartas não germinam. O objetivo deste trabalho foi estudar a sua biologia, descrever os danos causados pela praga e verificar o efeito de alguns tratamentos no controle dos adultos, por ingestão, em condições de laboratório (25 ± 2°C, UR de 65 ± 10% e fotofase de 14 horas).
