If we are to both understand and manipulate diamondback moth populations, a thorough grasp of P. xylostella population genetics is essential. However, reliable and informative molecular markers are currently unavailable. We have developed P. xylostella microsatellites and report preliminary results on their variability within and between selected populations. We characterised twelve microsatell...

Resistance to spinosad insecticide in field populations of diamondback moth was discovered at Kunia, Hawaii, in November 2000, about two and a half years after its introduction. Leaf-dip assays of field populations from the islands of Oahu, Maui and Hawaii confirmed moderate to high levels of resistance compared with pre-introduction baselines. Resistance occurred despite label restrictions tha...

Sustainability in food production is an increasingly discussed issue nowadays; therefore, demands for research that can reduce costs and ensure the quality autonomy of are relevant, with attention to use plants due their importance biodiversity. Thus, objective this was evaluate bioactivity, feeding preference, oviposition preference Miconia albicans botanical extracts at concentrations 1%, 5%,...

El objetivo de la presente investigación fue determinar eficiencia agrupación diversos componentes para el manejo integrado Plutella xylostella L. en cultivo brócoli (Brassica oleracea var. itálica). Se utilizó diseño bloques completamente al Azar (DBCA) con 4 tratamientos: Bacillus thuringensis / trampas luz/ barreras vivas maíz (T1), Metharhizium anisopliae a colores (T2), colores/ (T3), y co...

C-type lectins (CTLs) are a superfamily of Ca2+-dependent carbohydrate-recognition proteins, and an important pattern recognition receptor (PRR) in insect innate immunity which can mediate humoral cellular insects. In this study, we report novel dual domain (CRD) CTL from Plutella xylostella designate PxIML. PxIML is protein with 969 bp open reading frame (ORF) encoding 322 amino acids, contain...

Host plants affect development, survival, and reproduction of phytophagous insects. In the case of holometabolous species, whose larvae have little mobility to find a host plant, the ability of females to discriminate hosts on the basis of their nutritional quality may be an important factor determining insect performance. The preference‒performance correlation hypothesis states that females wi...

Abstract Pheromones have become an environmentally friendly alternative to conventional insecticides for pest control. Most current pheromone-based control products target lepidopteran pests of high-value crops, as today’s manufacturing processes cannot yet produce pheromones at low enough costs enable their use lower-value especially commodity crops. Camelina sativa seeds genetically modified ...
