Mealworms, Tenebrio molitor
Introduction: Mealworms are the worm-like larval form of a very dark brown beetle, Tenebrio molitor, a species which belongs to the genus Tenebrio and the family Tenebrionidae. The animal has other common names such as “Yellow mealworm”, “Mealworm beetle”, “Darkling beetle”, and “Darkening beetle”. The larval form is the usable form in pet’s keepers.
Distribution and habitats: Mealworms are found throughout most of the world in temperate regions, but primarily in the northern hemisphere. They thrive on grain and flour and are usually live near human habitation where their food sources are readily available. They prefer in dark, cool, and damp places like under decaying logs and leaves. When found inside homes, they

For self-defense, they spray noxious odor from scent glands.
Reproduction and life history: The mealworm is not a worm but the larval stage of the mealworm beetle which is also called the darkling beetle (Tenebrio molitor).
Like all holometabolic insects, the darkling beetle experiences a complete metamorphosis and goes through four distinct life stages: egg, larva, pupa, and adult. The duration of each stage varies significantly due to environmental factors such as temperature, humidity, and food. A female Darkling beetle lays about 270-500 small, white bean shaped eggs. Depending on water temperature, eggs hatch into tiny mealworm larvae in an average of about 10-12 days but this period could be much shorter while could extend to close 20 days or even beyond.
During the larval stage, and in order to grow, mealworms larvae undergo repeated molting/growth cycles. It is estimated that the number of molting may range from 10-20 times. By reaching the last molt and shedding its exoskeleton, the larvae lose its carapace before curling into its pupal form which is the third stage in the life cycle. The larval stage is the stage where the insect is a

They are commonly used in sports fishery as fishing bait such as for catching crappies or sunfish. In fact, there are various products of the mealworm prepared in a variety of forms for human consumption; some of which are sorted as healthcare foods.
The steadily increase in the prices of commercial fish feeds, stimulated searching and looking for less expensive feed for production economics reasons. Research projects have been designed to investigate the possibility of incorporating the mealworms in fish feed such as Nile tilapia and African catfish feed.
The manufacturers of fish feed in their attempts of replacing expensive ingredients such as fish meal by less expensive comparative ingredients are expected to benefit from research outcomes and commercialize it. The incorporation of the mealworms in on-farm feed preparation is most likely justified especially the production of the mealworms could be achieved on small farm level.
Away from its possible use in pet or aquaculture systems, Tenebrio molitor is being used as a model organism in biology laboratories for biology, biochemistry, evolution, immunology, and physiology. This is based on their relatively large size as well as the ease in their production and

    Corn borers attack mature plants because they need a stem large enough to hold their bodies. They lay eggs in clusters on the leaves. After hatching, they eat the leaves around the eggs for two weeks to a month, leaving close clusters of tiny holes. To catch borers early, look for the small holes. Later in the season look for small holes in the plant stalks, possibly covered with a thin silky webbing.…

    Mealworms Response to Dark and Light Sujit Vankineni Introduction: Mealworms are baby versions of adult black beetles. Mealworms are also considered the larvae stage of the black beetles. The mealworm has a hard outer body called the exoskeleton which is used for burrowing. The mealworms shed their skins a few times as they grow in a process called molting. The mealworm has four stages of growth which include egg, larvae (the mealworm), pupa, and the adult (the black beetle).…

    Caterpillars grow through time and increase in size each time they shed their skins which also known as molt. After molting, their skin is shed and develop a new one underneath which stretches and allows new growth. “They grow in the egg and then emerge throgh the shell, which they sometimes eat” (Miller & Hammond, 2003). Hadley (2014) noted that the caterpillar usually said to be five instar. “They may take a break from eating as it preparing to molt as it has to reach second instar” (Hadley, 2014).…

    The farm-raised fish usually have lower level of immunity and doses of antibiotics need to be given in order to ensure the fish free from diseases and lice. While, the wild-caught fish, which live in sea, have higher immunity level due to its natural lifestyles. It is important to consume only fish that are free from diseases because the fish with diseases maybe effect us by causing food-borne or any other worse diseases. The wild-caught fish also are free from any pesticides compared to the farm-raised fish, which usually are raised with pesticides to ensure a perfect look and “healthy” fish in order to attract costumers attraction.

    This next scenario is more complicated and involves plants, insects, parasitoids and humans. The tobacco hornworm (Manduca sexta) feeds on various species of the Solanale order which includes eggplants, potatoes, peppers, nightshades, tomatoes, petunias and of course, tobacco (Nicotiana attenuate). The larvae are defoliators and eat almost all of the leaves on a plant including fruit and blossoms. The larvae fill a different niche from their adult counterparts which feed on nectar. However, 70%-90% of foliage consumption is during the final instar.…
