Mosquito notes
Mosquitoes are found worldwide and transmit many diseases. They have three body parts - head, thorax, and abdomen. The female mosquito feeds on blood which it needs for egg production, while males feed on plant juices. Mosquitoes undergo complete metamorphosis from egg to larva to pupa to adult. The larvae live in water and the adult mosquito lives around 2 weeks. Different genera of mosquitoes transmit different diseases depending on their habitat and biting behaviors. Integrated control methods include eliminating breeding sites, using larvicides, biological controls, indoor residual sprays, and protective measures.
Prevention and control of ticks and mites
This document discusses strategies for preventing tick-borne diseases including environmental, personal, and prophylactic measures.

The city of Gainesville spends hundreds of thousands of dollars annually on its mosquito control program, which surveys citizens find is working reasonably well.
Heartwater disease (shared in slideshare 7.11.2014)
Heartwater is an acute, often fatal tick-borne disease of ruminants caused by the bacterium Ehrlichia ruminantium. It is widespread in sub-Saharan Africa and some Caribbean islands, where it can cause high mortality rates, especially in young animals and non-native breeds. The disease is characterized by neurological signs, respiratory signs, and systemic signs such as fever and loss of appetite. Diagnosis involves microscopic identification of E. ruminantium in tissues or molecular detection by PCR. Treatment during early stages may involve tetracyclines or sulfonamides, but prognosis is generally poor in advanced cases. Control relies on vaccination of young stock and ectoparasite control to reduce tick vectors.
Aedes aegypti

Sandfly notes
Sandflies are small, hairy insects that are vectors of diseases like leishmaniasis. They undergo complete metamorphosis from egg to larva to pupa to adult. As adults, they are nocturnal and breed in moist, organic-rich areas near dwellings. Their bite can transmit parasites and is painful. Control involves removing breeding sites, spraying insecticides, and using protective measures for people.
Ticks and mites
Ticks and mites are acarine vectors that can transmit diseases like scrub typhus and relapsing fever. They have life cycles involving egg, larval, nymph and adult stages. Mites are prevalent in hot, humid climates with thick vegetation and small vertebrate hosts, while ticks can be found in both rural and domestic settings. Control involves treating habitats with insecticides, managing vegetation, protecting individuals, and reducing rodent reservoirs.
Flea training
Fleas are small, wingless insects that feed on the blood of mammals and birds. They have laterally compressed bodies that allow them to move easily through fur or feathers. Fleas go through four life stages - egg, larva, pupa, and adult. All life stages can live in carpets. Effective flea control requires treating pets, vacuuming infested areas, washing bedding, applying insecticide to upholstery and carpets, treating outdoors around foundations, and repeated vacuuming after treatment to remove emerging fleas. Proper application and follow up is important to control flea populations.
Insect circulatory system
The insect circulatory system consists of a dorsal vessel (heart and aorta), hemocoel (body cavity), and pulsatile organs. The dorsal vessel runs longitudinally and pumps hemolymph (blood). It has two parts - the anterior aorta which extends into the thorax, and the posterior heart located in the abdomen with 9 chambers and ostia (lateral openings). The hemocoel facilitates circulation and contains hemolymph, a watery fluid composed of plasma, ions, sugars, proteins, lipids, waste products, and hemocytes (immune cells). Circulatory functions include transport, storage, providing hydraulic pressure for molting and movements, temperature regulation, and defense.
Nematode
Nematoda, or roundworms, are bilaterally symmetrical unsegmented worms that can be free-living or parasitic. They live throughout the world in various environments. Ascaris lumbricoides is one of the most common parasitic nematodes infecting humans. It lives in the small intestine where the female lays eggs that are passed in feces. After ingestion of embryonated eggs, the larvae hatch and migrate through tissues before maturing into adults in the intestine. Heavy infections can cause malnutrition and other complications.
ENTOMOLOGY-Sand fly
The document describes sand flies and rat fleas. Sand flies are small, winged insects that transmit diseases like kala azar. The female sand fly bites and sucks blood. Rat fleas are flattened parasites that live on rats and transmit diseases like plague. The female rat flea Xenopsylla cheopis is well-segmented with a semi-circular spermatheca. Control methods for both sand flies and rat fleas include removal of harborage, cleaning areas, and use of insecticides.

Many of these flies transmit viruses, bacteria, protozoa, and other pathogens through feeding on infected hosts or contaminated surfaces. Their worldwide distribution has been facilitated by close association with humans and livestock.
Rinderpest vpm
Rinderpest, also known as cattle plague, is a highly contagious and deadly viral disease affecting cattle and other cloven-hooved ruminants. It is characterized by fever, sores in the mouth, diarrhea, and high mortality rates. The virus is transmitted between animals through direct or indirect contact with secretions from infected hosts. While rinderpest has been eradicated globally through vaccination and control programs, it was once a severe problem affecting livestock in Africa and Asia. Treatment is ineffective but the disease can be controlled through quarantine, vaccination, and hygiene measures.
Fleas.pptx
Fleas undergo complete metamorphosis from egg to larva to pupa to adult. Common flea species include cat fleas, dog fleas, human fleas, chigoe fleas, sticktight fleas, oriental rat fleas, and rabbit fleas.

Vector control methods like larviciding and using larvivorous fish are also mentioned.
Q&A
Frogs belong to the class of amphibians, which evolved from fish around 270 million years ago. Amphibians include frogs, toads, newts, salamanders and caecilians. Frogs are cold-blooded and have soft skin, beginning life as larvae in water before metamorphosing into adults on land. Australia has approximately 219 frog species, over 90% of which are unique to Australia. However, at least 12 Australian frog species have gone extinct in the last 40 years, with 47 more considered threatened.

Adedes albopictus is most advanced stable species trophic level. It is acquired by after great nurture microevolution includes behavioral changes and survivality. In this evolutionary cascade, Ae. albopictus species diverged from its complex species lineage (reported in Kerala Ae. novalbopictus, Ae. pseudalbopictus and Ae. subalbopictus). Without any vestigial the species is pivotal in all the advanced measures include competition, adaptations, reproduction, and intelligence.

This document summarizes information about different tick species and the diseases they transmit. It discusses the lone star tick (Amblyomma americanum) which can transmit southern tick-associated rash illness, human ehrlichiosis, and tularemia. It also describes the blacklegged tick (Ixodes scapularis) which transmits Lyme disease, babesiosis, and anaplasmosis. Finally, it discusses the American dog tick (Dermacentor variabilis) which can transmit Rocky Mountain spotted fever. For each tick, it provides details on identification, life cycle, hosts, and the diseases they are able to transmit.
parasitology lab notes
Ticks are small, blood-feeding parasites that can transmit diseases to animals and humans. There are two main types of ticks - hard ticks and soft ticks. Ticks go through four life stages - egg, larva, nymph, and adult. Larvae and nymphs must feed on blood to molt into the next stage. Adults can transmit diseases while feeding. Some common tick species discussed include the brown dog tick, American dog tick, lone star tick, and deer tick. Proper tick removal is also described.

Some interesting facts about mosquito
Mosquitoes have been around for over 210 million years. They lay eggs in water that hatch into larvae and pupae, which mature in water before emerging as adult mosquitoes. Female mosquitoes require blood meals to develop eggs and are responsible for transmitting deadly diseases like malaria. Though they have a short lifespan of around 2-3 weeks, female mosquitoes can lay up to 300 eggs at a time, making mosquito prevention and control important. Effective methods include removing stagnant water, wearing light-colored clothing, using mosquito nets, and practicing good sanitation.
Arczi presents
Synanthropes are plant and animal species that live near and benefit from association with humans in habitats like houses, gardens, farms, and garbage dumps. This includes many regarded as pests like rodents, sparrows, and lice. In plants, synanthropes are classified as apophytes which are native species spread by human activities, or anthropophytes which are introduced, non-native species. Many common urban and household animals are considered synanthropes, having adapted to live commensally with humans, such as rats, flies, sparrows, opossums, and storks.

Aedes albopictus It is called “Asian Tiger” because of its Black and white striped legs Small black and white body A distinctive single white stripe runs the length of the back However, it can still be confused with other Aedes species such as Ae. pseudoalbopictus and Ae. scutellaris Ae. albopictus Ae. scutellaris
- 4. Presence and Activity Ae. albopictus is active the whole-year round in warm humid climates. Originally from tropical and sub-tropical regions, it can also adapt itself to live in cooler regions. It is considered as one of the “World’s Worst Invasive Species” by the Global Invasive Species Database. One cause of the mosquito’s wide area of invasion was due to the international tire trade which transported dormant mosquito eggs. The mosquito is able to survive in a wide range of habitats including cold mountainous areas. It bites from dawn to dusk.
