PRESENCE OF Orius insidiosus Say (HETEROPTERA: ANTHOCORIDAE) IN THE AZUERO REGION, PANAMA
Horticultural production in Panama is impacted by vector insects, from which Thrips palmi Karny stands out. This insect causes direct and indirect damage to economically important crops, which implies risks for production and agro-exports. The purpose of this research was to determine the presence of Orius insidiosus, its distribution and reservoirs, both cultivated plants and weeds. The study was carried out in the Azuero region, Panama. During the period from 2009 to 2021, samples were taken in 11 localities, both in crop areas and ruderal vegetation. All biological material was transferred to the Plant Protection laboratory of the Centro de Innovación Agropecuaria de Divisa, Instituto de Innovación Agropecuaria de Panamá, for identification. A total of 348 specimens belonging to the Orius insidiosus species were collected and identified, the sex ratio 61.5% female and 38.5% male. The insect is widely distributed in agroecosystems in the region, both in cultivated plants and weeds, natural reservoirs of the species. The predator was found in crops, with presence of Thysanoptera such as Thrips palmi and other species of the genus Frankliniella. This finding is important within the integrated management strategy of Thrips palmi, which includes natural, conservative, and classical biological control.
