Selectivity of neem to Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis (Hymenoptera: Trichogrammatidae).
Trichogramma pretiosum Riley and Trichogrammatoidea annulata De Santis are commonly found in avocado and persimmon orchards in northern Parana state. However, their abundance depends on whether insecticides are used or not to control the key lepidopteran pests Stenoma catenifer (Wals.) (Lepidoptera: Elachistidae) and Hypocala andremona (Stoll) (Lepidoptera: Noctuidae), respectively. The aim of ...
متن کاملHyperspectral Discrimination and Response Characteristics of Stressed Rice Leaves Caused by Rice Leaf Folder
Detecting plant health condition plays an important role in controlling disease and insect pest stresses in agricultural crops. In this study, we applied support vector classification machine (SVC) and principal components analysis (PCA) techniques for discriminating and classifying the normal and stressed paddy rice (Oryza sativa L.) leaves caused by rice leaf folder (Cnaphalocrocis medinalis ...
متن کاملReaction of major weeds and some rice cultivars to Alternaria pellucida- a potential biocontrol agent
Sagitaria trifolia, Alisma plantago-aquatica and Echinochloa spp. are among the most important damaging weeds in paddy fields. In this research, Alternaria pellucida was isolated from the weeds and then its pathogenicity effects was examined on these weeds and five other rice cultivars, including two bred (Sepidroud and Khazar) and three landraces (Ali Kazemi, Hashemi and Binam), in a completel...
متن کاملOptimized Scorpion Polypeptide LMX: A Pest Control Protein Effective against Rice Leaf Folder
Lepidopteran insect pests are the main class of pests causing significant damage to crop plant yields. Insecticidal scorpion peptides exhibit toxicity specific for insects. Here, we report that a peptide LMX, optimized from the insect-specific scorpion neurotoxin LqhIT2, showed high levels of activity against rice leaf folder in vitro and in planta. Oral ingestion of LMX protein led to a signif...
متن کاملTemperature Thresholds and Thermal Requirements for the Development of the Rice Leaf Folder, Cnaphalocrocis medinalis
The rice leaf folder, Cnaphalocrocis medinalis Guenée (Lepidoptera: Pyralidae) is a predominant foliage feeder in all the rice ecosystems. The objective of this study was to examine the development of leaf folder at 7 constant temperatures (18, 20, 25, 30, 32, 34, 35° C) and to estimate temperature thresholds and thermal constants for the forecasting models based on heat accumulation units, whi...
