Cryptolaemus montrouzieri

is 16°C/61°F. However, as Cryptolaemus montouzieri favors high temperatures, Cryptobug is most effective at temperatures between 25°C and 28°C (68 and [...] Above 33°C their searching behaviour comes to a standstill, while below 16°C they slow down until activity ceases at temperatures below 9°C. Life cycle [...] larvae resort to cannibalism under these conditions. At a temperature of 21°C, during the whole period of its development to adult beetle, a larva eats more

Brown root rot, corky root rot

between 8 and 32 °C, but the fungus prefers low temperatures. Therefore, optimal temperatures for disease development lie between 15 and 20 °C. Development [...] reduces at temperatures above 20 °C. The fungus produces pycnidia containing conidiophores with conidia and microsclerotia. Spread happens through dispersal
