Q

Larvae, larva

A

The form that hatches from the egg that under goes complete metamorphisis. After several molts that allow increase body size, the larva transforms into a different form (pupa) before reaching final form, adult.

21
Q

Respiratory of Anopheles

A

Breathe through a cluster of small abdominal plates, causing them to lie flat close to the surface

22
Q

Predaceous larvae species

A

Toxorhynchites rutilis, Psorophora ciliata- prey on invertebrates including mosquito larvae.

23
Q

Larvae eat

A

Fliter feeders ingesting 10 micron or less

24
Q

Larvae development

A

Depending on species and environment - 3 to 4 days to several weeks to complete larvae development. Mature 4th instar molt to pupa.

25
Q

Instar

A

Form of insect between molts

26
Q

Pupae, pupa

A

Immature stage between larva and adult in insects going through full metamorphosis.

27
Q

Piercing -sucking

A

One of the basic types of insect mouthparts. Mouth parts for piercing tissue to gain access to fluids such as blood (female mosquito)

28
Q

Respiratory pupae

A

Breathe through two “horns”

29
Q

Pupa development

A

Do not feed, transform to adult in two or more days

30
Q

Adult mosquito

A

Terrestrial, capable of flight, females piercing sucking mouth parts feed on blood and plant nectar. Male antennae have dense bristles and mouth parts to suck nectar and plant secretions. Some adults remain within a few hundred feet of where they were larvae; some adults migrate 50+ miles.

31
Q

Aquatic veg, water lettuce, water hyacinth, cattails

A

Coquillettidia perturbans, Mansonia dyari, Mansonia titillians

32
Q

Bromeliad and pitcher plants

A

Wyeomyia spp

33
Q

Larvae habitat categories

A

Standing water (permanent and transient), floodwater (natural and artificial containers and floodwater).

34
Q

Standing water species

A

Deposit eggs (single or raft) on the surface of permanent or transient pools. Usually produce several generations (broods) each year. Overwinter or survive harsh environments as mated, engorged females.

35
Q

Floodwater species

A

Deposit eggs out of water in locations subject to periodic flooding, such as damp soil, tree holes, crab holes, artificial containers. Produce one to several broods annually. Overwinter or survive harsh environment inegg stage.

36
Q

Standing water- permanent water group

A

Anopheles spp, Culex (Melanconium) spp, Culex salinarius, Culex territans, Coquillettidia spp, Mansonia spp

37
Q

Permanent, freshwater marsh

A

38
Q

Permanent, lakes

A

Larvae found when many species of floating or emergent plants are present. When veg occurs in narrow band along shoreline, larvae are confined to this littoral zone.

43
Q

Transient water group

A

44
Q

Transient, Salt or brackish water ditches

A

Many species of grasses support large mosquito fauna. Ochlerotatus taeniorhynchus, Ochlerotatus sollicitans, Anopheles bradleyi

45
Q

Transient, borrow pits and canals

A

Man-made bodies of open water produce more mosquitoes as they silt and grow veg. Anopheles quadrimaculatus spp, Culiseta inornata, Psorophora columbiae, Ochlerotatus canadensis, Culex nigripalpus, Culex quinquefasciatus , Culex restuans, Culex salinarius, Anopheles albimanus, Coquillettidia perturbans, Mansonia spp.
