This flyer and fold-out poster provides ways to conserve wild bee populations. Wild bees pollinate a wide variety of food and fiber crops. As managed honey bee populations experience periodic declines due to parasites and disease, wild bees may help supplement pollination services. Who are these wild bees? How can we enhance their activity? Wild bees, which include native and naturalized bees, pollinate a variety of crops, including apples, pears, nuts, strawberries, tomatoes, peppers, blueberries, squash, and melons.
In areas of Pennsylvania, wild bees already provide the majority of pollination for some summer vegetable crops. Bees have a reputation for producing painful stings, partly because of stings inflicted by hornets, yellow jackets, and other wasps. However, most wild bees are not aggressive because they are solitary nesters and thus do not have large colonies to defend.
The risk of getting stung by a wild bee is low. We can conserve and attract wild bee species to Pennsylvania by increasing the amount of floral resources in the area, conserving natural habitats in the landscape, providing access to clean water, creating or conserving nesting sites, and reducing bee exposure to pesticides. Many studies have shown that wild bee diversity increases as the proportion of natural habitat in the surrounding landscape increases.
Forests, meadows, and wetlands provide wild bees with nesting sites and floral resources, especially early in the spring when flowers may be scarce. Fortunately, community groups can work with nonprofit organizations, conservation land trusts, and local municipalities to acquire and protect natural lands through grant programs like the Community Conservation Partnership Program C2P2 , managed by Pennsylvania's Department of Conservation and Natural Resources DCNR.
Land managers can also conserve natural habitats on their properties by maintaining flowering plants in their field margins. Bees need pollen and nectar together called floral resources to survive and reproduce. To provide wild bees with food throughout the growing season, plant a variety of flowering plants with overlapping bloom periods. Land managers can increase access to floral resources for wild bees by:. Bumble bee on a tomato flower at Penn State's community garden.
Bees need water for survival. It is especially important to provide water to bees during the summer months when water resources in the landscape can be limiting. On-site water sources should be clean and free of pesticides and may include:. The majority of wild bees are solitary nesters--females create individual nests in soil, plant material, or abandoned nests of other animals.
Natural bee nests can be protected by not tilling the area or exposing it to broad-spectrum pesticides. Maintaining a diversity of natural and artificial nesting areas can increase the likelihood that wild bees will nest on site.
Nesting sites may include:. Constructed nest boxes can be used for wood nesters like the blue orchard bee. Bees may be poisoned or killed when they come into contact with pesticides found on leaves and flowers on which they forage or the soil where they nest. When chemical controls are necessary, take special care by:. Approximately 4, described bee species exist in North America.
More than species occur in Pennsylvania. These hairy, large-bodied, mostly long-tongued bees are considered the second most important pollinators after the honey bee. With their ability to buzz pollinate vibrate pollen off anthers , bumble bees are efficient pollinators of crops that are not frequented by honey bees. Colonies are established each spring by a single queen. Crops visited: blueberries, cane berries, orchard crops, peppers, tomatoes, and others. Bumble bee. This group of small, short-tongued bees range in color from metallic blue and green to brown and black.
Most species are solitary, and a few are attracted to the salts in human sweat. Sweat bee. These solitary bees are black with white, silver, or orange hairs. Females frequently nest in rotting wood and line the interior with small pieces of leaves. Unlike most bees that carry pollen on their hind legs, leafcutter bees transfer pollen on the underside of their abdomens.
Leafcutter bee. The squash bee is an efficient pollinator of squash plants and related crops. This solitary, ground-nesting species will visit flowers at temperatures and under light conditions that are unsuitable for most other pollinators. Squash bee. Large portable colonies, a broad diet, and copious honey production make this species highly desirable as a managed pollinator. Unfortunately, colony numbers are on the decline in North America and other parts of the globe.
Crops visited: orchard crops, squash, melon, soybeans, sunflower, alfalfa, and others. Honey bee. Mason bees are prized for their efficient pollination of orchard crops in spring. Both native and introduced species have been successfully managed by providing nesting boxes or tubes that can be stored in a sheltered location over the winter. Mason bee. These solitary, mostly short-tongued bees are rightfully termed "mining bees" for their habit of excavating pencil-thin nests in the ground.
These are among the first bees to emerge in the spring. Mining bee. Bees come in many different shapes and sizes. Some are covered with hairs while others are almost completely bald. It is also common for males and females of the same species to look very different.
Below are silhouettes of representative species from each of the bee groups discussed here. Figure 1. Size and shape comparison of the seven bees discussed above. When crops are not in bloom, the vegetation surrounding fields can provide vital food resources for pollinators. Wildflowers, shrubs, and even large trees can supply bees with important sources of pollen and nectar.
Cover crops are plants grown in agricultural fields and gardens for a number of reasons, including reducing erosion, increasing soil fertility, and suppressing weeds.
If allowed to bloom, some cover crops can also help support bee populations. However, take care to terminate the cover crop before it sets seed to avoid any potential weed problems. Examples of flowering cover crop species: Buckwheat top , Hairy Vetch middle , Clover bottom.
Native plants are well adapted to the local weather and soil conditions. They have co-evolved with the insect communities in our region, and they are less likely to become a nuisance in agricultural settings compared to exotic plants, which may become invasive or weedy.

In the European Union, biological control should be preferred to conventional chemical methods if they provide satisfactory pest reduction.

Vegetable oils are triglycerides extracted from plants. Some of these oils have been part of human culture for millennia. Many oils, edible and otherwise, are burned as fuel, such as in oil lamps and as a substitute for petroleum -based fuels. Some of the many other uses include wood finishing , oil painting , and skin care. The term "vegetable oil" can be narrowly defined as referring only to substances that are liquid at room temperature,  or broadly defined without regard to a substance's state liquid or solid at a given temperature. Vegetable oils can be classified in several ways. For instance, by their use or by the method used to extract them. In this article, vegetable oils are grouped in common classes of use. There are several types of plant oils , distinguished by the method used to extract the oil from the plant.

Rice is the staple food for Asian people; it is prepared by cooking or ground as flour for bread making, thus helping to feed the rest of the world population. Various kinds of rice are produced to suit the taste of the consumers. Rice cultivation is done either in marshy, lowland areas with plenty of water or in plateau or hilly regions where natural rainfall provides adequate amounts of water. Rice can be cultivated either by hand or by partial or full mechanization, according to the technological development of the country and the need for productivity. Whatever kind of operation is done, the following step-by-step processes are necessary.

Twelve millennia ago, humankind moved into the Neolithic era and discovered that food, feed and fibre could be produced from the cultivation of plants. This discovery has led to the food and fibre supply that feeds and clothes more than 5 billion people today. This general profile of the agricultural industry includes its evolution and structure, economic importance of different crop commodities and characteristics of the industry and workforce.
