Lately in horticultural agroecosystems from Romania joined several insect species autochthonous. Among these is a species of bugs known as southern green stink bugs or Nezara viridula L. (Insecta: Hemiptera: Pentatomidae). Unlike other new entrants this bug species has a diversified polifagism being present in many plants but obvious damage produce only tomato fruit. The causes are unknown. Can be found in gardens, green spaces and parks. Often is observed in vegetable gardens where populations

... comprise all stages (egg, larva/nymph, adult). Although it has African origins of a warm area is interesting installation and survival in temperate zones like those in Europe. Presence in Europe appears to be more random which excludes primarily spread through the neighborhood. By observations made in west of Romania, during 2010-2015 we wanted to watch the evolution of the insect from the first point of occurrence (Timișoara, 2010). Also, were monitored tomato crops and ornamentals in gardens and green spaces from 5 counties. Only in four monitored counties it was observed this species. Most adults and larvae were registered in Timis county (5-6 adults or 7-8 larvae/tomato plant and 10 -11 adults or 15-20 larvae/ornamental shrub). In our country the insect has proven to be capable of a rapid spread in a relatively short time interval including surrounding counties.
