See All Pollinators

In this video series from Penn State Extension, scientists discuss populations of wild bees, honey bees, and best management practices to achieve pollination and encourage and protect these critical pollinators.

Managed pollinators like honey bees and mason bees are important pollinators for orchards, but research suggests that wild bees also contribute significantly to fruit tree pollination.

Growers of bee-pollinated crops, particularly apples, may be interested in the possible use of solitary bees as pollinators.

Pollination involves the integration of several biological and physical factors, including cultivar compatibility, synchronous blooming, insects, and proper weather conditions.

Honey bees are infected with many different kinds of viruses. However, most virus infections are not problematic, if the honey bee colony is healthy and does not experience chronic stress.

In addition to honey bees, which are managed, various un-managed species that exist as wild populations play key roles in providing pollination of cucurbit crops.

El género Cucurbita contiene distintas especies de calabaza (también conocidas como: calabaceras, calabacines o zapallos). En los Estados Unidos, las plantas de calabaza son comunes en granjas y jardines en todo el país.

Instructions for successfully introducing an instrumentally inseminated honey bee queen into a colony before she has started laying eggs.

Learn about the various nest types of stinging insects, including honey bees, bumble bees, yellowjackets, and mud daubers, and how they build and defend them.

Learn about differences between social and solitary bees, wasps, and hornets, including colony behavior, nesting, and defensive behavior.

The spotted lanternfly, Lycorma delicatula, is an introduced plant hopper from China that is rapidly expanding its range in the United States.

Varroa mites (Varroa destructor), are the most influential of all of the pests and diseases of the European honey bee (Apis mellifera) today.

Beneficial insects are those that consume or parasitize insect pests.

American foulbrood attacks honey bee larvae, weakening the colony and quickly leading to its death.

The queen is the most important individual in a colony. She is the only bee capable of producing workers and tens of thousands of workers are required for strong colonies.

Pollinators need a diverse, abundant food source and a place to build their nests and rear their young. If we keep these two elements in mind, we can encourage native bee populations.

Domestic honey bee hives are down by 59% compared to 60 years ago, with rapid declines over the last forty years. The populations of some native bee species may also be declining.

Wild bees, which include native and naturalized bees, pollinate a variety of crops. In areas of Pennsylvania, wild bees already provide the majority of pollination for some summer vegetable crops.

Common tree fruit questions from home gardeners are "Why do my trees fail to bear fruit?" or "Why do they only have fruit every other year?"
