Managing orchard groundcover to reduce pollinator foraging post‐bloom

چکیده
BACKGROUND Agricultural insecticides are believed to play a role in global pollinator decline. In mass-flowering orchard crops, recommendations reduce exposure of pollinators include spraying at periods when bees aren't foraging, such as dusk and dawn outside crop flowering times. However, the presence weeds within orchards mean may still be found foraging throughout growing season, increasing likelihood that will occur. We hypothesized removing these groundcover post-bloom thus this group pesticides. tested hypothesis by using herbicide remove broadleaf sod middles (‘groundcover’) between rows nectarine New Jersey, USA, assessing effect on visitation via three different methods. RESULTS Significantly lower abundance, richness, diversity, evenness were plots where treatment had removed majority weeds, compared untreated plots. This was case for bees, overall, reflected both visual observations active sampling through sweep netting. Passive with blue vane traps failed detect difference treatments. CONCLUSION Groundcover management is often employed part integrated pest programs alternative host plants insect pests. The findings study show it also effective reducing orchards, potentially preventing beneficial organisms harmful insecticides. © 2021 Society Chemical Industry.

Effects of groundcover management on ground beetles (Coleoptera: Carabidae) in an apple orchard
A field experiment was conducted in a cider-apple orchard to evaluate the effect of six groundcover management systems (pine-bark, plastic and straw mulches, tillage, herbicide and natural soil) on the occurrence of ground beetles (Coleoptera: Carabidae). Eight species of carabids were collected in pitfall traps. The three most common beetles, Steropus gallega Fairmaire (65.8%), Pseudophonus ru...
متن کاملProximity to Woodland and Landscape Structure Drives Pollinator Visitation in Apple Orchard Ecosystem
Landscapes of farms and adjacent areas are known to influence abundance of various arthropods such as pollinators in commercial agricultural ecosystems. In this context, we examined the effect of heterogeneous landscapes surrounding and including commercial apple orchards on pollinator visitation and foraging distance during bloom period from 2011 to 2013 in Pennsylvania. Our results showed tha...
متن کاملPollinator Foraging Adaptation and Coexistence of Competing Plants
We use the optimal foraging theory to study coexistence between two plant species and a generalist pollinator. We compare conditions for plant coexistence for non-adaptive vs. adaptive pollinators that adjust their foraging strategy to maximize fitness. When pollinators have fixed preferences, we show that plant coexistence typically requires both weak competition between plants for resources (...
متن کاملIntelligent In-Orchard Bin-Managing System for Tree Fruit Production
The labor-intensive nature of harvest in the tree fruit industry makes it particularly sensitive to labor shortages. Technological innovation is thus critical in order to meet current demands without significantly increasing prices. This paper introduces a robotic system to help human workers during fruit harvest. A second-generation prototype is currently being built and simulation results dem...
