With over 90 different crops relying on bees for their pollination services, we have to take a moment this week to thank a bee for the food on our tables. #PollinatorWeek2021 2/n
Here are a variety of crops that 50% or more of their yield is dependent on pollinators, we would probably not have these foods without our insect friends! #PollinatorWeek2021 3/n
Some native solitary bees have evolved very specialized relationships with crop species, like squash bees #PollinatorWeek2021 4/n
The alfalfa leafcutter bee (Megachile rotundata) and the horn-faced bee (Osmia cornifrons) are both managed solitary bee species that were introduced to US to increase pollination of alfalfa and orchard crops #PollinatorWeek2021 5/n
Blueberry plants are pollinated by many different bees including bumblebees and specialist like southeastern blueberry bee and two specialist mining bees.
Generalist pollinators like honey bees are capable of pollinating many crops #PollinatorWeek2021 7/n
Some crops are not effected by pollinators at all (like corn, rice, wheat) while others can develop without pollinators but their yield is increased when they are around, like soybeans. #PollinatorWeek2021 8/n
A study of the impacts of pollinators on crops around the world found that wild pollinators increase yield in ALL crops systems while honey bees increased yield in only 14% of systems. science.sciencemag.org/content/339/61…
In Pennsylvania there are over 400 species of bees, in the US there are over 4000.
A survey of the general public found that "only 14%
of people were able to guess within 1000 the actual number of bee species in the US" digitalcommons.usu.edu/cgi/viewconten…
For #PollinatorWeek2021 we’re excited to showcase some fun info about bee pollinators, especially ones we work with in the López-Uribe Lab. Today is all about squash bees!
A thread:
Squash bees are ground nesting solitary bees that pollinate plants in the genus Cucurbita, such as pumpkins, squash, zucchini, and other gourds.
Squash bees do look similar to honey bees but ecologically they are very different. Honey bees live in huge hives and squash bees are solitary. Here are tips to help you tell them apart
