Entomology- Recent Advances, Innovations and Implications

Recent advances in entomology have transformed agriculture, biotechnology, and health. CRISPR gene editing in insects improves pest management and disease prevention, while biopesticides and precision agriculture provide environmentally friendly alternatives to chemical pesticides. Insect-based protein manufacturing and robots inspired by insect behavior are gaining interest as solutions to global food security and technology issues. Meanwhile, … Read more

Insects with Forensic Entomology and Nutritional Importance

by
Insects with Forensic Entomology and Nutritional Importance

In Forensic entomology, species such as blowflies and beetles are critical for determining the time of death in human bodies because they inhabit and decay remains in predictable patterns. Insects serve important roles in forensic science and nutrition. Insects like crickets, mealworms, and grasshoppers provide a high-protein, sustainable food source that is rich in critical … Read more

Insects of public health importance

by
Insects of public health importance

Insects of public health concern include those that harm human health by transferring diseases, inducing allergic reactions, or infesting homes. Examples include mosquitoes, which spread malaria, dengue, and Zika; flies and cockroaches, which contaminate food and spread bacteria; ticks and fleas, which transmit diseases like Lyme disease and plague; and lice and bed bugs, which … Read more

by
Introduction to industrial insects honey bees, silkworms and lac insects

Industrial insects such as honey bees, silkworms, and lac insects contribute significantly to a variety of industries by creating useful products. Honey bees are vital for pollination, honey, and beeswax production, which is crucial in agriculture, food, and cosmetics. Silkworms produce silk, a valued natural fiber used in textiles and biotechnology. Lac insects secrete lac, … Read more

Introduction to veterinary insects

by
Introduction to veterinary insects

Veterinary insects are arthropods that have an impact on animal health by functioning as parasites, disease vectors, or causing irritation and allergies. Flies, ticks, lice, fleas, mites, and mosquitoes are among the key groups that can spread diseases such as heartworm, Lyme disease, and mange, as well as causing anemia and skin problems. Veterinary entomology … Read more

Sprayers: Parts, Calibration and Calculation of Pesticides

by
Sprayers Parts, Calibration and Calculation of Pesticides

Sprayers are essential equipment for effective pesticide application in agriculture, pest control, and gardening. The tank, pump, nozzles, pressure regulator, and control valve are all essential components. Proper calibration ensures that the sprayer applies the appropriate amount of pesticide, eliminating over- or under-application. This includes metering the sprayer’s output, inspecting the nozzles, and adjusting pressure … Read more

Insect Collection, Killing, and Preservation

by
Insect Collection, Killing, and Preservation

Insect collection, killing, and preservation are necessary processes for scientific research, education, and personal collections. Insects are collected using methods such as handpicking, sweep netting, and trapping. They are then murdered gently with methods such as ethyl acetate in killing jars, freezing, or alcohol immersion. Depending on the size and type of the insect preservation … Read more

Insect Classification: Introduction to insect orders, their characteristics, and keys

by
Insect Classification Introduction to insect orders, their characteristics, and keys

Insect classification, a system for categorizing insects in the class Insecta, groups these immensely diverse arthropods based on characteristics such as segmented bodies, exoskeletons, three pairs of legs, and, in many cases, wings. They are distinguished by a segmented body, an exoskeleton, jointed legs, and occasionally wings. Insect Classification are categorized into different orders depending … Read more

Bioluminescence and Sound Production In Insects

by
Bioluminescence and Sound Production In Insects

Bioluminescence and sound production are two unique insect adaptations utilized largely for communication, mating, and defense. Bioluminescence, which is visible in species such as fireflies, is the production of light by a chemical reaction involving luciferin and luciferase, and is frequently utilized to attract mates or discourage predators. Crickets and cicadas produce sound by mechanisms … Read more
