The concept of a pest is based on human purposes and perceptions. Under this criterion, a pest is an organism that has characteristics regarded by humans as injurious or unwanted. Usually, an organism is identified as a pest because it is harmful to agricultural activities or the ecosystem, or carries germs within human habitats. Examples include those organisms that Face Fly Green Bottle Fly House Fly vector human disease, such as rats and mosquitoes. The term may also include fungi and viruses. This Pocket Guide lists some of the common insect pests found in the home and in the lawn for identification purposes. Control options are not discussed in this guide. Some of these insects Louisville Water Company 550 S. 3rd Street may not be considered to be a pest in the lawn and garden, but Louisville, KY 40202 are certainly a pest in the home, while others are considered to 502-569-3600 be pests wherever they may be located.

Effective pest management and Page 10 Page 3 reduced use of pesticides are compatible. Pesticides used correctly and judiciously are good tools for pest control. However, pesticides should not be used if non-pesticidal approaches can solve the problem. The first step in any pest control program is to identify the pest.

    SCHOOLS INTEGRATED PEST MANAGEMENT (IPM) FOR WASPS AND BEES *Important Note* According to the Virginia Pesticide Control Act (Section 3.1-249.53), in order to apply ANY pesticide (including Raid, Round-Up, and other over-the-counter pesticides) in public areas of ANY educational institution, the applicator must first be certified by the Virginia Department of Agriculture and Consumer Services. In other words, it is illegal for uncertified teachers, staff, administrators, or contractors to apply pesticides on school grounds. INTRODUCTION Bees and wasps experience “complete metamorphosis”.

    Clothes Moths ENTFACT-609 By Michael F. Potter, Extension Entomologist, University of Kentucky Clothes moths are pests that can destroy fabric and other materials. They feed exclusively on animal fibers, especially wool, fur, silk, feathers, felt, and leather. These materials contain keratin, a fibrous protein that the worm-like larvae of the clothes moth can digest. (In nature, the larvae feed on the nesting materials or carcasses of birds and mam- mals.)

  • Clothes Moths
    Clothes Moths Integrated Pest Management in the Home The webbing clothes moth, Tineola bisselliella, (Figure 1) and casemaking clothes moth, Tinea pellionella, (Figure 2) can be fabric pests in California. They tend to hide when disturbed, so you might not notice you have an infestation until after the moths have already dam- aged your fabric, fur, or feathered items. Close examination of the objects will reveal silken webs the larvae have spun. Figure 1. Webbing clothes moth. Figure 3. Casemaking clothes moth with IDENTIFICATION its case attached. The webbing clothes moth is the most common fabric moth. The adult is gold with reddish-golden hairs on the top of its head. A row of golden hairs fringes its wings, which have a span of about 1/2 inch. Because these moths are weak flyers that aren’t attracted to lights, you’ll usually find them close to the infested items, such as in a dark area of the closet. Figure 2. Casemaking clothes moth.

  • Preventing Pests and Pathogens in Honey Bee Colonies
    BestBest ManagementManagement PracticesPractices toto PreventPrevent thethe SpreadSpread ofof PestsPests andand PathogensPathogens inin HoneybeeHoneybee ColoniesColonies Photos by Rob Snyder (used with permission) Many pest and disease problems in managed honeybee hives can be avoided by practic- ing good sanitation and cultural controls. Prevention is the first and best line of defense against organisms that can harm your colonies. Sanitation Tools should be sterilized with flame and scrubbed with isopropyl alcohol after working in or inspecting a hive. Avoid using other beekeeper’s tools that have not been properly cleaned. Clothing and gloves that are exposed to a hive where disease is suspected needs to be scrubbed and disinfected with 10% bleach solution or disposed. If not using gloves, rinse hands with rubbing alcohol then scrub with soap and water after working in a hive that appears to have been infected with disease. When disease is suspected, practice the previously mentioned steps between working hive to hive in the same beeyard. Cultural Controls When purchasing a bee colony, find out if the seller has been treating with antibiotics for patho- gens. Treated colonies could already be infected with disease, even in the absence of symptoms. Never switch frames from a box that is suspected to have pests and pathogens to a box without such problems. Do not purchase or accept used frames, boxes, or other beekeeping equipment that have not been inspected and certified by your county’s bee inspector. Boxes infected with American Foulbrood should be marked with the letters “AFB” followed by the year to prevent unintentional contamination. Equipment that has been infected with American Foulbrood must be treated or burned and buried.

  • PESTS of STORED PRODUCTS a 'Pest of Stored Products' Can Refer To
    PESTS OF STORED PRODUCTS A ‘pest of stored products’ can refer to any organism that infests and damages stored food, books and documents, fabrics, leather, carpets, and any other dried or preserved item that is not used shortly after it is delivered to a location, or moved regularly. Technically, these pests can include microorganisms such as fungi and bacteria, arthropods such as insects and mites, and vertebrates such as rodents and birds. Stored product pests are responsible for the loss of millions of dollars every year in contaminated products, as well as destruction of important documents and heritage artifacts in homes, offices and museums. Many of these pests are brought indoors in items that were infested when purchased. Others originate indoors when susceptible items are stored under poor storage conditions, or when stray individual pests gain access to them. Storage pests often go unnoticed because they infest items that are not regularly used and they may be very small in size. Infestations are noticed when the pests emerge from storage, to disperse or sometimes as a result of crowding or after having exhausted a particular food source, and search for new sources of food and harborage. Unexplained occurrences of minute moths and beetles flying in large numbers near stored items, or crawling over countertops, walls and ceilings, powdery residues below and surrounding stored items, and stale odors in pantries and closets can all indicate a possible storage pest infestation. Infestations in stored whole grains or beans can also be detected when these are soaked in water, and hollowed out seeds rise to the surface, along with the adult stages of the pests, and other debris.

It is the caterpillar (larval stage) of these insects that does the actual feeding. Clothes moths feed on all kinds of dry materials of animal origin including woolens, mohair, hair, bristles, fur and feathers. Holes are chewed in items or threadbare spots caused where fibers are chewed in carpeting. Household items that may be attacked include clothing, drapes, pillows, hair mattresses, brushes, upholstery, furs, piano felts or other natural or synthetic fabrics mixed with wool. Silken feeding tubes or hard pro- Case-making Clothes Moth tective cases are often found on infested fabrics. DESCRIPTION: The adult moths of these two species look very much alike. They are yellow- ish-tan to buff-colored with a wingspread of about ½ inch. The larvae are white with brown to black heads, and are also about ½ inch long. The case-making clothes moth larvae spin a protec- tive case out of silk and material fibers, often blending in with the fabric so damage is not noticed until a bare spot or hole is produced. The webbing clothes moth spins silk over the fibers it is feeding on but does not form a case around itself until ready to enter the pupa (resting stage). Webbing Clothes Moth Adult & Larvae LIFE HISTORY: Female clothes moths deposit soft white eggs in clothing and household furnishings.

  • Entomophagy As Bio-Prospecting
    © 2018 JETIR February 2018, Volume 5, Issue 2 www.jetir.org (ISSN-2349-5162) ENTOMOPHAGY AS BIO-PROSPECTING K. Ashok, K. Aravinth Raju 1. Student, B.Sc., (Ag),Faculty of Agriculture, Annamalai University, Chidambaram, Tamil Nadu, India 2. Student, B.Sc., (Ag), Faculty of Agriculture, Annamalai University, Chidambaram, Tamil Nadu, India Abstract: Entomophagy is using insects as human food. Insect as food play an important role in new insect focus. Ants, bees, termites, caterpillars, water bugs, beetle larvae, flies, crickets, katydids, cicadas, and dragonfly naiads are among a long list of edible insects that provide for the people of Asia, Australia, Africa, South America, the Middle East, and the Far East. Insects represent an important food source for a wide variety of other animal species. By weight termites, grasshoppers, caterpillars, weevils, houseflies, and spiders are better sources of protein than beef, chicken, pork or lamb. The nutritional and economic value of edible insects is often neglected and we should further encourage their collection and commercialization, given the benefits to the environment and human health. It is an interesting concept, managing pest insects by developing them into a sought after delicacy. Keywords: Insectivory, Entomophagy, Traditional knowledge, Insect bio prospecting. Introduction: Bioprospecting is the collecting and cribbling of biological samples (plants, animals, microorganisms) and the collecting of indigenous knowledge to help in discovering genetic or biochemical resources. Bioprospecting is intended for economic purposes (e.g., new drugs, crops, industrial products). Many insects contributed on a regular basis to the Indian diet. Ants, bees, termites, caterpillars, water bugs, beetle larvae, flies, crickets, katydids, cicadas, and dragonfly nymphs are among a long list of edible insects that provide nutrition for the people of Asia, Australia, Africa, South America, the Middle East, and the Far East.

Gailce Leo Justin1 Tamil Nadu Agricultural University, Coimbatore-641003, Tamil Nadu, India 1Anbil Dharmalingam Agricultural College and Research Institute, Tamil Nadu Agricultural University, Tiruchirappalli-620027, Tamil Nadu, India *Corresponding author: [email protected] Received: Aug 30, 2020; Accepted: Oct 22, 2020 Introduction Entomological Warfare (EW) is a type of Biological Warfare (BW) that uses insects as war weapons, tools of terrorism and creating nuisance from ancient period to modern period. Minimum 12 insect orders have been used as biological weapon, which are classified into three categories based on damages viz., direct and indirect. In the first category, insect toxins were weaponized, particularly in Hymenoptera to inflict pain to assailants and second category involves use of insect as pests of agricultural crops which cause severe economic damage. In the third, disease transmitting insect vectors like Anopheles mosquitoes (transmitting malaria), etc. were used. Insect borne pathogens of humans, livestock and agricultural crops constituted more risk in bioterrorism. In the 14th century, Asia Minor plague transmitted through fleas (Black Death) was one of the earliest events of using insect as biological weapons during World War II (Chaudhry et al., 2017). This paper clearly discusses the ways in which insects have been used as biological warfare. Ancient and modern history Ancient people know about using insects as weapons to attack and to protect themselves from enemies, where hornet was used to dislodge entrenched enemies. In Persian practice, dipteran flies were used to torture prisoner, by forcing the flies to cause diarrhoea until the enemies succumbed to myiasis and septic.
