Scirtothrips dorsalis occurs in Colombia
In Colombia, the presence of Scirtothrips dorsalis (Thysanoptera: Thripidae – EPPO A2 List) was first recorded in 2012 in the departments of Huila, Tolima and Vichada*. A study was carried out from 2013 to 2016 to better understand its distribution in Colombia. Samples were collected in different agro-ecosystems and different altitudes (up to 3 000 m asl). S. dorsalis was found in the Andean, Caribbean and Orinoquia regions of Colombia, at altitudes ranging from 0 to 1 200 m asl in the warm climate zone. The authors concluded that according to their results, S. dorsalis was not widely distributed in Colombia, possibly due to unfavourable climatic conditions (e.g. low temperatures, high rainfall) and the presence of different geographic barriers. Concerning host plants, larvae and adults of S. dorsalis were found in cultivated plants: Capsicum annuum (sweet pepper), Capsicum frutescens (chili pepper), Citrus sinensis (orange), Gossypium hirsutum (cotton), Mangifera indica (mango), Murraya paniculata (jasmine orange), Rosa sp., as well on weeds and wild plants: Amaranthus spinosus, Echinochloa colona, Euphorbia hypericifolia, Ludwigia hyssopifolia, Phyllanthus niruri, Sesbania herbacea (=S. exaltata).
The situation of Scirtothrips dorsalis in Colombia can be described as follows: Present, only in some areas (Andean, Caribbean and Orinoquia regions).
* The EPPO Secretariat had previously no information on the presence of S. dorsalis in Colombia.
