“…It would be interesting to test whether ilarvirus infection in peach trees alters pollinator attraction. As bees are well known for their pollination and ecological services (Thakur 2012, Decourtye et al 2019, Boecking and Veromann 2020, Requier et al 2023), PNRSV and PDV management strategies should be focused on eradicating virus-inoculum sources (i.e., infected trees). More research is needed to understand the dynamics of PNRSV and PDV at the peach-wild hosts interface to identify the pattern of virus movement.…”

Prunus necrotic ringspot virus (PNRSV) and prune dwarf virus (PDV) are pollen-borne viruses of important stone fruit crops, including peaches, which can cause substantial yield loss. Although both horizontal and vertical (i.e., seed) transmission of both viruses occurs through pollen, the role of flower-visiting insects in their transmission is not well understood. Bees and thrips reportedly spread PNRSV and PDV in orchards and greenhouse studies; however, the field spread of PNRSV and PDV in peach orchards in the southeastern United States is not explored. We hypothesized that bees and thrips may facilitate virus spread by carrying virus-positive pollen. Our 2-yr survey results show that 75% of captured bees are carrying virus-positive pollen and moving across the orchard while a subsample of thrips were also found virus positive. Based on morphology, Bombus, Apis, Andrena, Eucera, and Habropoda are the predominant bee genera that were captured in peach orchards. Understanding the role of bees and thrips in the spread of PNRSV and PDV will enhance our understanding of pollen-borne virus ecology.

“…Plant-pollinator interaction is vitally important to terrestrial ecosystems and to crop production. It plays a key role in plant community assembly (Bruno et al, 2003;Ollerton et al, 2011;Wright et al, 2017;Hale et al, 2020) and thus provides critical ecosystem services with immense economic and aesthetic value (Klein et al, 2007;Potts et al, 2016;Requier et al, 2022;Gallai et al, 2009). Despite their immense importance, rapid decline events of many pollinators are frequent in recent years (Burkle et al, 2013;Rhodes, 2018).An important issue today is to determining how human activities impact the varied relationships between plants and their insect pollinators for the sake of conservation.…”

“…Metacommunity models of mutualistic species is studied considering habitat loss as a parameter, showing that there is a habitat loss threshold after which whole community collapses (Fortuna and Bascompte, 2006) and the number of interaction of the network reduces suddenly (Fortuna et al, 2013). Other environmental stressors affecting mutualistic interaction strength by causing phenological change of species can magnify the effect of habitat loss, when acts together (Revilla et al, 2015). Epidemic models are developed (Truitt et al, 2019;Proesmans et al, 2021) to study the disease spread on plant-pollinator network, and nestedness is shown to promote disease persistence as highly generalist plants acts as hubs of pathogen transmission.…”

Mutually beneficial interactions between plant and pollinators play an essential role in the biodiversity, stability of the ecosystem and crop production. Despite their immense importance, rapid decline events of pollinators are common worldwide in past decades. Excessive use of chemical pesticides is one of the most important threat to pollination in the current era of anthropogenic changes. Pesticides are applied to the plants to increase their growth by killing harmful pests and pollinators accumulates toxic pesticides from the interacting plants directly from the nectar and pollen. This has a significant adverse effect on the pollinator growth and the mutualism which in turn can cause an abrupt collapse of the community however predicting the fate of such community dynamics remains a blur under the alarming rise in the dependency of chemical pesticides. We mathematically modeled the influence of pesticides in a multispecies mutualistic community and used 105 real plant-pollinator networks sampled worldwide as well as simulated networks, to assess its detrimental effect on the plant-pollinator mutualistic networks. Our results indicate that the persistence of the community is strongly influenced by the level of pesticide and catastrophic and irreversible community collapse may occur due to pesticide. Furthermore, a species rich, highly nested community with low connectance and modularity has greater potential to function under the influence of pesticide. We finally proposed a realistic intervention strategy which involves the management of the pesticide level of one targeted plant from the community. We show that our intervention strategy can significantly delay the collapse of the community. Overall our study

“…Insect pollination is an important contributor to our ecosystem and biodiversity 1 . Because of various factors, the populations of pollinating insects, especially bees, have become significantly reduced 1,2 . The most important of these factors are abiotic stressors, such as environmental pollution and climate change 2 .…”

BACKGROUNDEnvironmental stress can induce oxidative stress in A. cerana cerana, leading to cellular oxidative damage, reduced vitality, and even death. Currently, due to an incomplete understanding of the molecular mechanisms by which A. cerana cerana resists oxidative damage, there is no available method to mitigate the risk of this type of damage. Cyclin plays an important role in cell stress resistance. The aim of this study was to explore the in vivo protection of cyclin H against oxidative damage induced by abiotic stress in A. cerana cerana and clarify the mechanism of action. We isolated and identified the AccCyclin H gene in A. cerana cerana and analysed its responses to different exogenous stresses.RESULTSThe results showed that different oxidative stressors can induce or inhibit the expression of AccCyclin H. After RNAi‐mediated AccCyclin H silencing, the activity of antioxidant‐related genes and related enzymes was inhibited, and trehalose metabolism was reduced. AccCyclin H gene silencing reduced A. cerana cerana high‐temperature tolerance. Exogenous trehalose supplementation enhanced the total antioxidant capacity of A. cerana cerana, reduced the accumulation of oxidants, and improved the viability of A. cerana cerana under high‐temperature stress.CONCLUSIONOur findings suggest that trehalose can alleviate adverse stress and that AccCyclin H may participate in oxidative stress reactions by regulating trehalose metabolism.This article is protected by copyright.
