greenhouse - Opis:
- The aim of this study is to determine the effects of insect net placed on ventilation openings in greenhouses on temperature, humidity and radiation energy from indoor conditions. In addition, the effects of insect net on the agents used in biological control have been tried to be determined. The study was carried out between November 2017 and May 2018 in Kumluca district of Antalya in 2 glass and 2 plastic greenhouses. Greenhouses; the glass greenhouse without insect net (GCG), the glass greenhouse with insect net (GNG), the plastic greenhouse without insect net (PCG), the plastic greenhouse with insect net (PNG) is named as. Temperature, humidity and solar radiation values were measured in greenhouses. According to the results of the research; It was determined that the recommended temperature values for pepper development are only suitable in January and well below the recommended values in February. In other production months, the average temperature values of with insect net greenhouses (PNG-GNG) used in ventilation openings were found to be higher than without insect net greenhouses (PCG-GCG). When the results of relative humidity values were examined, it was observed that the use of insect tulle in the greenhouses was lower than the control greenhouses. It was determined that the solar radiation values were lower than the control greenhouses (PCG-GCG) of the insect tulle greenhouses (PNGGNG) in other months except January and May. Therefore, we can say that the use of insect net reduces the amount of solar radiation. Accord ing to the results of temperature values; the growth of Orius Leavigatus and Amblyseius swirski, one of the biological agents and resistant to high temperatures, was observed to slow down in all other months except February. For Phytoseiulus persimilis (30°C and above), we can say that this is a suitable environment and that the eggs have emerged in a shorter time. The most suitable average temperature for the development of Aphidius colemani was reached only in January. In other months, the development of this agent slows down, parasitic insecticides can be said to decrease the rate of parasitoids. As a result; It was determined that the temperature values were higher in the greenhouses where insect net was used and the solar radiation values were lower than the control greenhouses. However, since the use of insect net causes the temperature in the greenhouse to increase, it may create a positive development for some bio agents. It is thought that producers using insect net should make production considering these negativities in temperature and solar radiation.
