Resumen:
The use of anti-insect screens placed on greenhouse vents has become generalized in warm climate areas, where there is a big pressure from insect pests which transmit virus diseases. Increasing the efficiency of the screens to reduce the entrance of pests into the greenhouse generally involves a reduction of the ventilation rate as the screen porosity is lower. This can, in part, be compensated by using screens with lower diameter of the threads which allows a higher porosity forthe same efficiency to exclude insects. In the present work the characteristics of the most commonly used anti-insect screens in Almería greenhouses, including ...
