Advances in control of onion thrips (Thysanoptera: Thripidae) in cabbage.
Onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), feeding injury results in discoloration and a rough texture on cabbage, Brassica oleracea capitata (L.), leaves, and damage may occur deep inside the head. It has become a key pest of cabbage in the United States and many other countries. Previous studies have indicated poor control using insecticides. The present study identified ...
متن کاملEstimating Phenology of Agricultural Crops from Space
This paper summarises the main results derived from a study developed under the ESA funded PolSAR-Ap project, aimed to demonstrate the contribution of SAR polarimetry in diverse Earth observation products. The specific application treated here is the retrieval of phenology of agricultural crops by exploiting C-band polarimetric images. Using a set of 20 images acquired by Radarsat-2 during the ...
متن کاملAnalysis of Resistance in Cabbage Varieties to Damage by Lepidoptera and Thysanoptera
J. Econ. Entomo!. 81(2): 634-640 (1988) ABSTRACT Differences in susceptibility to damage by Thrips tabaci Lindeman and the lepidopteran pest complex (Plutella xylostella (L.), Artogeia rapae (L.), and Trichoplusia ni (Hiibner)) were documented and analyzed for fresh market and experimental cabbage varieties. Patterns of resistance to damage were different for Lepidoptera and T. tabaci. The comm...
متن کاملSpecies composition and population dynamics of thrips (Thysanoptera) in mango orchards of northern peninsular Malaysia.
Thrips are key pests of mango, Mangifera indica (L.), in Malaysia, including the Northern Peninsular. As Penang has year-round equatorial climate and high of rainfall, the populations of thrips may be subject to variations in composition and size. With a goal of developing an appropriate control strategy, a survey was conducted in Penang to determine species composition and abundance in relati...
