The use of observation bee hives continues to interest a variety of people. This is not surprising. The observation hive is one of the primary research and educational tools in apiculture. It is both educational and entertaining. Observation bee hives can be used to enhance public relations and marketing programs. But a great deal of time and energy is needed to set up a hive and keep it going. Maintenance can be expensive and time consuming, especially if the hive is to be used as a permanent display for the general public. This 3-page fact sheet provides sources for building observation hives and tips for maintenance. Written by David Hall, James D. Ellis, and Malcolm Sanford, and published by the UF Department of Entomology and Nematology, March 2015. (UF/IFAS photo by Tyler Jones)

Sting Nematode Belonolaimus longicaudatus Rau (Nematoda: Tylenchida: Belonolaimidae)

Figure 1. Sting nematode Belonolaimus longicaudatus. Credit: W. T. Crow, University of FloridaAmong the most destructive plant-parasitic nematodes to a wide range of plants, Belonolaimus longicaudatus damages plant roots. When the plants cannot take up water and nutrients from the soil, they become stunted, wilt, and with severe infestation, die. Florida is considered to be the point-of-origin for Belonolaimus longicaudatus and therefore this nematode exhibits a great deal of diversity in morphology, host preference, and genetics in our region.

Daane, University of CaliforniaAnagyrus pseudococci is an economically important biological control agent commonly used against the vine mealybug (which infests wine grapes) and the citrus mealybug. It is a solitary, internal parasitoid and lays one egg per host, with the larva developing inside the host’s body. The wasps may be commercially reared and distributed inside mummies, and they will emerge within 1-5 days after delivery. Application involves placing a bottle containing the mummies in a dry spot of the crop and allowing the adults to emerge. This 5-page fact sheet was written by Theresa Chormanski and Ronald D.

Figure 1. A tawny crazy ant, Nylanderia fulva (Mayr), worker. Credit: Lyle J. Buss, University of FloridaNylanderia fulva is part of a group of ants referred to as “crazy ants” due to their quick and erratic movements. It has been reported from 27 counties of Florida and 27 counties of Texas, as well as from Louisiana, Mississippi, Alabama and Georgia. Huge number of workers in infested areas can make human activities uncomfortable and difficult. They can infest sidewalks, buildings and gardens, and damage phone lines, air conditioning units and computers. They have killed honey bee larvae and used the hives as their nests, and are even displacing red imported fire ants where the two populations overlap in Texas.

Figure 3. Epicorsia oedipodalis caterpillar on fiddlewood. Credit: W.H. Kern, Jr., UF/IFAS/FLRECThese caterpillars roll up leaves of the host plants and use the rolled leaves as larval retreats and locations for pupal cocoons. Although these leaf-eating pests do no permanent damage, they can completely defoliate fiddlewood, a Florida native that can form a large shrub or small tree. The shrub simply puts out a new flush of leaves. The larvae themselves are valuable food source for baby birds during the spring dry season in Florida.

Credit: Haleigh RayThis predatory mite was recently discovered in an unsprayed greenhouse at the University of Florida, Gainesville, living on Phalaenopsis and Dendrobium orchids, and assumed to be feeding on orchid pests such as spider mites, tenuipalpid mites, and mealybugs that were present on the orchids. Because there was no published information on this species as a natural enemy of orchid pests, colonies were initiated here to study its biology, maintained on two-spotted spider mite prey. Hemicheyletia wellsina does not appear likely to be an effective natural enemy in agricultural crops as an introduced predator, but could be beneficial in natural biological control in natural ecosystems, where pest densities are lower.

Yellowmargined Leaf Beetle: A Pest of Cole Crops

igure 1. A young mustard plant being eaten by YMLB adults and larvae.The yellowmargined leaf beetle is a pest of cole or cruciferous crops that is native to South America. Since first reported in Mobile, Alabama, in 1947, the beetle has spread throughout the Gulf Coast from Texas to Florida and up into Georgia and North Carolina. It has also been reported from Illinois and California. Not considered a major pest in conventionally grown cruciferous crops because it is susceptible to a wide range of insecticides, it poses a significant threat to the growing organic industry in the southeastern United States. It is a particular problem on Asian greens such as mizuna, mibuna, and napa cabbage, as well as on other high-value cruciferous crops like turnip, mustard, and watercress.

Robbing Behavior in Honey Bees

Figure 1. The colonies in this apiary are being equalized (i.e. populations are being made uniform). Having many colonies open at the same time caused the bees from the colonies to initiate a robbing frenzy.Western honey bee workers can invade and steal honey/nectar from other colonies or sugar/corn syrup from feeders used to deliver syrup to other colonies. This is called “robbing” behavior. Robbing behavior typically involves the collection of nectar and honey, but not pollen or brood. Some beekeepers report that robbing bees may steal wax or propolis from other hives, but there is not much data available on this occurrence. Robbing behavior can escalate quickly from just a few bees robbing other colonies to a massive frenzy of bees robbing many colonies in an apiary.

Urban Pests and Pest Management

Figure 1. This fact sheet is excerpted from SP486: Pests in and around the Southern Home, which is available from the UF/IFAS Extension Bookstore. http://ifasbooks.ifas.ufl.edu/p-1222-pests-in-and-around-the-southern-home.aspxThe warm southern states provide an ideal environment for a wide variety of pests — and because almost everyone has problems with pests, most urban areas are sprayed with pesticides. 30 to 40 percent of pesticide use is in urban areas, but most pesticide applications are unnecessary and can result in environmental contamination and human exposure to pesticides. This 5-page fact sheet from Pests in and around the Southern Home introduces integrated pest management practices that can help reduce pesticide use in the home. Written by P.G.

Wedge-Shaped Beetles (suggested common name) Ripiphorus spp. (Insecta: Coleoptera: Ripiphoridae)

Figure 1. Adult specimen of Macrosiagon HentzRipiphoridae are a family of unusual parasitic beetles that are thought to be related to tumbling flower beetles and blister beetles. They parasitize bees and wasps, roaches, and wood-boring beetles, but specific hosts for many ripiphorid species are unknown. Their secretive life cycle makes an assessment of their economic and ecological impact very difficult. Additional research is necessary to determine the abundance and impact of Ripiphorus species.
