Declining populations of bee pollinators are a cause of concern, with major repercussions for biodiversity loss and food security. RNA viruses associated with honeybees represent a potential threat to other insect pollinators, but the extent of this threat is poorly understood. This study aims to attain a detailed understanding of the current and ongoing risk of emerging infectious disease (EID...

Honeybees (Apis mellifera) are principal insect pollinators, whose worldwide distribution and abundance is known to largely depend on climatic conditions. However, the presence records dataset on potential distribution of honeybees in Indian Ocean Islands remain less documented. Presence records in shape format and probability of occurrence of honeybees with different temperature change scenari...

In this paper, new concepts for continuous 24/7 real-time monitoring of plants and insects with miniaturized terahertz (THz) systems are described experimentally tested. Thus, the first time, small-scale insights into instantaneous plant health but also in their long-term growth can be obtained. Using such compact THz systems, e.g. water uptake, insect infestation behavior pollinators (i.e. hon...

Insect pollination is one of the most important ecosystem services. Pollinator communities are rarely studied across years and crops in same location. The aim this study was to investigate pollinator community structure on five different fruit crops, as well activity groups during day their temperature preferences. observed two apple trees blueberry, strawberry, blackcurrant raspberry bushes. v...

Abstract Insect nesting boxes and hotels have the potential to provide shelter overwintering sites for beneficial insect communities such as pollinating bees, wasps, earwigs, other predatory arthropods. This study evaluated arthropod visitation consumer-ready, commercially available over a 2-yr period. were placed on mature river birch (Betula nigra L.) crape myrtle (Lagerstroemia indica in gar...

Pollinating insects provide pollination services to many crop species, including sweet cherry (Prunus avium L.), and this can be delivered by both managed wild pollinators. Managed pollinators are often used pollinate a range of fruit crops, but increasingly the role is being studied. However, importance pollinator species depends on their relative abundance effectiveness, which foraging activi...

Abstract Expanding cities increasingly encroach fertile farmlands, questioning the viability of maintaining agriculture within and around them. Yet, our knowledge on how urbanization influences pollinator communities provision pollination services to crops is limited, especially for hotspots Global South. Mango Mangifera indica one most important fruit in tropical countries. To analyse dependen...
