Apis mellifera is a pollinator insect model in pesticide risk assessment tests for bees. However, given the economic and ecological importance of stingless bees such as Melipona scutellaris Neotropical region, well lack studies on effect insecticides these bees, toxicity should be carried out to understand whether affect both species same manner.

The banana weevil (BW), Cosmopolites sordidus, is the main coleopteran pest of banana, causing up to 100% yield loss. In this study, we screened 20 isolates entomopathogenic fungi (EPF) for management BW. lab, eight Beauveria bassiana caused >50% mortality adult BW, whereas Metarhizium anisopliae and Isaria fumosorosea were less pathogenic.

Planting healthy seedlings with optimal growth potential is essential for proper and survival in forest regeneration. Assessing the seedling quality prior to planting therefore important. In this Icelandic study, effects of root damage induced artificial freezing young Russian larch were examined using capacity method (RGC). Frost tolerance roots varied during winter, undamaged fluctuated, indi...
