Darkling Beetles A CAROLINA™ CareSheet Care and handling Darkling Beetles are the adult stage of over 20,000 species; however, we use Darkling Beetle to refer to the adult of the Superworm (Zophobas morio). If you are interested in the adult of Tenebrio molitor, see the Mealworm CareSheet. The larval stage of Zophobas is known as the Superworm and has its own CareSheet. Habitat A terrarium makes a good habitat for this beetle. Put 1 ½ to 2” of potting soil in the bottom of the tank. Cover the surface with paper towels, leaf litter, or bran meal/oat flakes. They do best in dark, cool, dry places. Maintenance These beetles extract water from their food. Additionally, their hard carapace is covered with a wax-like substance that prevents water from evaporating from their bodies. If you wish to give supplemental water, place a moistened sponge or cotton wick into the habitat Adult Darkling Beetles are scavengers, eating both fresh and decaying vegetation. In nature, they feed on dried or rotting plant matter. In captivity, they feed on bran meal, apples, oranges, potatoes, cucumber, romaine lettuce, and pears. Remove uneaten food before it molds. Darkling beetles are active both during the day and at night. With simple care, they can live from three months to over a year. FAQ’s Can these beetles bite? No, they are completely harmless. Their only defense is to release a mildly offensive odor. Can Darkling Beetles be held in a refrigerator? No, temperatures below 15.5ºC (60ºF) may kill the beetles. Can these beetles be released? No, they are native to South and Central America. They have the potential to survive and establish themselves in the wild in the southern United States. Unwanted Darkling Beetles should be frozen or fed to a pet reptile or amphibian. Problems? We hope not, but if so contact us. We want you to have a good experience.

Mountain Pine Beetle Voltinism and Life History Characteristics Across Latitudinal and Elevational Gradients in the Western United States
For. Sci. 60(3):434–449 FUNDAMENTAL RESEARCH http://dx.doi.org/10.5849/forsci.13-056 entomology & pathology Mountain Pine Beetle Voltinism and Life History Characteristics across Latitudinal and Elevational Gradients in the Western United States Barbara Bentz, James Vandygriff, Camille Jensen, Tom Coleman, Patricia Maloney, Sheri Smith, Amanda Grady, and Greta Schen-Langenheim Substantial genetic variation in development time is known to exist among mountain pine beetle (Dendroctonus ponderosae Hopkins) populations across the western United States. The effect of this variation on geographic patterns in voltinism (generation time) and thermal requirements to produce specific voltinism pathways have not been investigated. The influence of voltinism on fitness traits, body size, and sex ratio is also unclear. We monitored mountain pine beetle voltinism, adult body size, sex ratio, and air temperatures at sites across latitudinal and elevational gradients in the western United States. With the exception of two sites at the coolest and warmest locations, the number of days required to complete a generation was similar. Thermal units required to achieve a generation, however, were significantly less for individuals at the coolest sites. Evolved adaptations explain this pattern, including developmental rates and thresholds that serve to synchronize cohorts and minimize cold-sensitive life stages in winter. These same adaptations reduce the capacity of mountain pine beetle at the warmest sites to take full advantage of increased thermal units, limiting the capacity for bivoltinism within the current realized distribution. Temperature was not correlated with adult size and sex ratio, and size was greatest in host trees other than lodgepole pine (Pinus contorta Dougl.).

It can also cause damage to poultry housing and is suspected to be a health risk to humans in close contact with larvae and adults. Adults can become a nuisance when they move en masse toward artificial lights generated by residences near fields where beetle-infested manure has been spread (Axtell 1999). Alphitobius diaperinus inhabits poultry droppings and litter and is considered a significant pest in the poultry industry. Numerous studies have been conducted on lesser meal- worm biology, physiology, and management. Lambkin (2001) conducted a thorough review of relevant scientific literature in reference to A. diaperinus and provides a good understanding of the biology, ecology and bionomics of the pest. Bruvo et al. (1995) conducted molecular work to determine satellite DNA variants on the chromosomes of A. diaperinus. Alphitobius diaperinus is a member of the tenebrionid tribe Alphitobiini (Doyen 1989), which comprises four genera worldwide (Aalbu et al. 2002). Two genera occur Figure 1.

Eating insects is also interesting in terms of low greenhouse gas emissions and low land use. In contrast to tropical countries, where most of the 2000 edible insect species are traditionally consumed, the concept of eating insects is still new to Western culture and diet. Culture and eating habits exert a great inﬂuence on what is considered edible in the Mediterranean area, especially in Italy, where the preservation of culinary traditions is a predominant factor aﬀecting dietary behaviour. The purpose of this narrative paper is to provide an overview of the main topics related to entomophagy.

Darkling Beetles and Mealworms Theresa A
Darkling Beetles and Mealworms Theresa A. Dellinger and Eric R. Day, Department of Entomology, Virginia Tech Description Darkling beetles belong in the beetle family Tenebrionidae, which consists of more than 20,000 species of beetles. Adult darkling beetles widely range in shape and size, with most measuring from 2 – 19 mm (0.13” – 0.75”). Adults are usually a reddish-brown to brownish-black in color and can be shiny or dull. The elytra (the wing covers) can be smooth, grooved, or otherwise sculptured. Most do not have colorful patterns on their wing covers. Adults are most active at night and tend to avoid bright lights. Darkling beetle larvae are often referred to as mealworms or false wireworms. They are long, hard-bodied grubs with a cylindrical shape and are shiny yellow-brown to darKer brown in color. They are active crawlers. Yellow mealworm larva, top. Dark mealworm larva, bottom. Clemson University-USDA Cooperative Adult yellow mealworm, Tenebrio molitor. Extension Slide Series, Bugwood.org. Clemson University-USDA Cooperative Extension Slide Series, Bugwood.org. Life Cycle Darkling beetles have a complete life cycle with egg, larval, pupal, and adult stages. Most species of darkling beetles have a slow rate of development and may live for a year as an adult. Species living on grains or other stored products may develop faster. Habitat/Distribution Darkling beetles are found throughout the world except for places with very cold climates. They are scavengers and omnivores, feeding on decomposing plant material, dead insects, fungi, and stored products. Only a handful of darkling beetles are considered pests; the vast majority of them live in the wild and pose no harm.

Despite extensive research and development in antibiotics, they have remained inadequately effective in treating bovine mastitis induced by multiple pathogen infection. In the present study, we showed the protective effect of Zophobas morio (Z. morio) hemolymph on bovine mammary epithelial cells against bacterial infection. Z. morio hemolymph directly kills both Gram-positive and Gram-negative bacteria through membrane permeation and prevents the adhesion of E. coli or the clinically isolated S. simulans strain to bovine mammary epithelial (MAC-T) cells. In addition, Z. morio hemolymph downregulates the expression of nucleotide-binding oligomerization domain (NOD)-like receptor family member pyrin domain-containing protein 3 (NLRP3), caspase-1, and NLRP6, as well as inhibits the secretion of interleukin-1β (IL-1β) and IL-18, which attenuates E. coli or S. simulans-induced pyroptosis. Overall, our results suggest the potential role of Z. morio hemolymph as a novel therapeutic candidate for bovine mastitis.

Zophobas Morio Zophobas Morio ) Are a 2” Long Larva That Is a Very Popular) Area2”Longlarvathatisvery © Do Not Copy Withoutpermission© Donotcopy
Superworm Zophobas morio By Cody Castellanos General Information: Superworms ( Zophobas morio ) are a 2” long larva that is a very popular feeder for reptiles. Because of their size and movement they’ll easily catch the attention of your animals. They are naturally large and have no growth hormones unlike the giant mealworm. They are native to tropical Central and South America. The total life span for a superworm is a little over a year from egg to beetle. Housing: They can be placed in any container that you may have. Make sure that the container is high enough so they can’t climb out. Usually tubs 5”+ high is sufﬁ cient. I’ve found that plastic Rubbermaid tubs usually work best. Heat & Light - Lighting is not needed as they like darkness. The best temperatures are in the mid 70s to the low 80s. If superworms are overheated you will notice a signiﬁ cant die off. Also never refrigerate superworms! They can’t take cold temperatures and death will be the result. Food & Water: Superworms will eat just about anything. Keep them in 1-4” of wheat bran, oats or a highly nutritious gutload. Make sure to gutload all food items for 24 hours prior to feeding. Gutloading is feeding very nutritious/high quality foods to prey prior to feeding to your animals. There are also many commercially available products that are in powder form. I make and use Pro Gutload for all my feeders. Gutloading will ensure a healthier insect and in the long run a healthier animal. Water - Things like carrots, potatoes, fruits etc are all suitable for moisture.
