conditions The parasitic wasps are most effective at temperatures around 25°C/77°F. The lowest temperature at which development can occur is 13°C/55°F;
pest mites are detected in the crop. Introduction rates typically range from 25-300 per m2/release. Releases should be repeated if necessary. Consult a Koppert
species found in the tropics. In temperate regions they are not larger than 2.5 mm. All thrips species that cause damage in green-houses belong to the family
psyllid Adult Asian citrus psyllids are mottled brown wings insects of about 25 to 35 mm long. The adults are active, jumping/flying insects and can readily

germination. In general, the development rate of the epidemic is fastest at 18-25 °C. High relative humidity (RH) promotes germination of spores but inhibits
conditions Encarsia formosa is most effective at temperatures between 20°C and 25°C (68 and 77°F). At a 24 hours average temperature below 17°C/63°F the control
favourable conditions for the development of the pathogen are temperatures between 25 and 30 ºC, relative humidity of over 90%, and a soil pH of under 7. The ideal
climate. A full-grown beet armyworm (Spodoptera exigua) caterpillar can be 25 to 38 mm in length, with dark, wrinkled stripes dorsally and a yellow band
parasitic wasp Anagyrus vladimiri is most effective at temperatures around 25°C/77°F. The lowest temperature at which development can occur is 13°C/55°F;
