More than 100,000 species of insects live in North America. While some insects are harmful, most play important roles in ecosystems by pollinating plants, decomposing matter, and forming parts of the food chain. Insects have three body sections - a head, thorax, and abdomen. They undergo different life cycles including incomplete, gradual, and complete metamorphosis. Understanding insects provides insight into their roles in environments.
Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms.
Nearly all insects hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages often differ from the adults in structure, habit and habitat, and can include a passive pupal stage in those groups that undergo four-stage metamorphosis. Insects that undergo three-stage metamorphosis lack a pupal stage and adults develop through a series of nymphal stages.[6] The higher level relationship of the insects is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22 to 28 in). The most diverse insect groups appear to have coevolved with flowering plants.
Adult insects typically move about by walking, flying, or sometimes swimming. As it allows for rapid yet stable movement, many insects adopt a tripedal gait in which they walk with their legs touching the ground in alternating triangles, composed of the front and rear on one side with the middle on the other side. Insects are the only invertebrates to have evolved flight, and all flying insects derive from one common ancestor. Many insects spend at least part of their lives under water, with larval adaptations that include gills, and some adult insects are aquatic and have adaptations for swimming. Some species, such as water striders, are capable of walking on the surface of water. Insects are mostly solitary, but some, such as certain bees, ants and termites, are social and live in large, well-organized colonies. Some insects, such as earwigs, show maternal care, guarding their eggs and young. Insects can communicate with each other in a variety of ways. Male moths can sense the pheromones of female moths over great distances. Other species communicate with sounds: crickets stridulate, or rub their wings together, to attract a mate and repel other males. Lampyrid beetles communicate with light.

The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

2. More than 100,000 species of insects are found almost
everywhere in North America, but very few are harmful.
Insects are important to the food chain, pollination, honey, wax,
shellac, silk, food, scavenging, and decomposing.

In school we learned that
animals are divided into
smaller and smaller
groups. Let's look where
insects fit in the animal
kingdom. From top to
bottom, each category has
fewer species, and the
groups of animals within
each category are
increasingly similar.
7. • Kingdom- animalKingdom- animal
• Phylum - arthropodPhylum - arthropod
• Class - insectClass - insect
• Order - dipteraOrder - diptera
• Family - muscidaeFamily - muscidae
• Genus -Genus - MuscaMusca
• species -species - domesticadomestica
Using the house fly as
an example. Notice the
genus and species is
the official scientific
name of the animal.
This name is valid in
any country of the
world and is an
important way to
avoid confusion. This
two-word Latin
naming system was
developed in 1758 and
has hardly changed
since then. There are
some important things
to know about it.
8. House FlyHouse Fly
MuscaMusca == flyfly
domesticadomestica = home= home
Scientific names are always two words. The first part of the name
(Genus) is always capitalized. This lets us know that it is the genus.
The second name is always in lower case and is usually descriptive of
the insect in some manner. Because these words are in Latin, they are
always italicized (or underlined which substitutes for italics).
13. Insects also have common names.
One problem with common names is that there may be more
than one common name for the same insect. Common
names often differ between geographical regions. Do you
know what a skeeter hawk is? Or a cow killer? Did you
know a velvet ant really is not an ant, but a wingless
wasp? ...and locusts are really a type of grasshopper - not a
cicada.
15. honeybee
bumble beebumble beehoney beehoney bee
Important rules govern the use of common names. If the insect truly
belongs to the group that the name denotes, then the common name should
be two words. For example, a honey bee is a true member of the bees, so
honey bee (or bumble bee) is always spelled as two words despite what
your common dictionary may print.

22. Two Examples ofTwo Examples of MouthpartsMouthparts
chewingchewing piercing/suckingpiercing/sucking
Insect mouthparts are also highly modified for the
insect. Chewing, biting, or sucking, are a few examples.
Mouthparts of an immature insect may differ from those of
the same insect in its adult stage.
23. Picture of bodyparts
ThoraxThorax
The middle body region is
called the thorax and is
composed of three fused
segments. All legs and
wings are located on the
thorax.
25. AbdomenAbdomen
The last body region is
called the abdomen. It is
composed of many segments
connected by flexible
sections allowing it great
movement.
26. Insects possess an exterior covering called the
exoskeleton. They do not have internal bones. This
segmented "shell" is what gives insects shape and can
be very hard in some insects. It is often covered with a
waxy layer and may have "hairs" called setae.
28. InternalInternal
AnatomyAnatomy
Inside the insect we find the systems for respiration,
circulation, nerves, and digestion, but there is little
resemblance to the same systems found in man or other
mammals.
29. Digestive sys
Digestive SystemDigestive System
foregutforegut
midgutmidgut
hindguthindgut
The digestive system is a tube that opens at the mouth and empties at
the tail end of the insect. It is divided into three parts called the
foregut, midgut, and hind gut. In some insects such as the honey bee,
the foregut acts as a crop to carry or hold liquids which can be
regurgitated later.
30. Circ system
Circulatory SystemCirculatory System
aortic pumpsaortic pumps““ heart ”heart ”
The circulatory system is not composed of a central heart, veins and
arteries which circulate blood cells and transport oxygen. The insect
circulatory system is a simple tube down the back which is open at both
ends and slowly pulses body fluids and nutrients from the rear of the
insect to the head.
31. Nervous system
Nervous SystemNervous System
nerve bundlesnerve bundles
two lobed braintwo lobed brain
(ganglia)(ganglia)
Insects have a less centralized nervous system than humans. The nerve
chord runs along the ventral or bottom aspect of an insect. The brain is
divided into two main parts. The largest lobes control important areas
such as the eyes, antennae, and mouthparts. Other major concentrations
of nerve bundles called ganglia occur along the nerve chord and usually
control those body functions closest to it.
32. The respiratory system is composed of air sacs and tubes
called tracheae. Air enters the tubes through a series of
openings called spiracles found along the sides of the body.
The largest spiracles are usually found on the thorax where
greater musculature from wings and legs require more
oxygen. There are no spiracles on the head.
34. LifeLife
CyclesCycles
The many diverse orders of insects have four different types of life cycles.
These life cycles are called "metamorphosis" because of the changes of
shape that the insects undergo during development.
35. Without meta

eggegg adultadultnymphsnymphs
The first type is "without" metamorphosis which the
wingless primitive orders such as silverfish (Thysanura)
and springtails (Collembola) possess. The young resemble
adults except for size.
36. Incomplete meta

The second type is "incomplete" metamorphosis
which is found among the aquatic insect orders such as
mayflies (Ephemeroptera) and dragonflies (Odonata).

eggegg nymphsnymphs adultadult
The third type is "gradual" metamorphosis seen in such orders as the
grasshoppers (Orthoptera), termites (Isoptera), thrips (Thysanoptera),
and true bugs (Hemiptera). This life cycle starts as an egg, but each
growth, or nymphal stage looks similar, except it lacks wings and the
reproductive capacity that the adult possesses.
38. Complete MetamorphosisComplete Metamorphosis
eggegg larvaelarvae pupapupa adultadult
The fourth type is "complete" metamorphosis found in butterflies
(Lepidoptera), beetles (Coleoptera), flies (Diptera), and bees, wasps, and
ants (Hymenoptera). This life cycle has the four stages of egg, larva,
pupa, and adult. Each stage is quite distinct.
39. recently molted roachrecently molted roach
It should be noted that because insects are hard-bodied,
they cannot grow larger gradually. Instead they grow
larger in steps by shedding the hard exoskeleton for a
brief period of expansion. The brief periods between or
within stages are called molts. Insects are soft-bodied
and vulnerable during this time.
