Mosquito speices in alaska.
Alaska is home to 35 known mosquito species, each adapted to its unique environment. These species can be broadly categorized into two groups: snow mosquitoes, which emerge early in the season, and summer mosquitoes, which appear later.Anchorage Daily News
đŠ Mosquito Species in Alaska
While a comprehensive list of all 35 species is extensive, here are some notable examples:
- Aedes communis: Common in wooded areas; known for aggressive biting behavior.My Favorite Animal Postcards
- Culiseta alaskaensis: Also known as the Alaskan winter mosquito; active in cooler temperatures. Wikipedia
- Aedes impiger: Found in tundra regions; prevalent in northern parts of Alaska.
- Aedes nigripes: Adapted to arctic environments; one of the few species active during colder months.
These species vary in habitat preference, behavior, and seasonal activity. For a detailed identification key, refer to the Identification Key for United States and Alaska Mosquito Genera.Defense Centers for Public Health

What is Geranial ?
Geranial is a naturally occurring monoterpenoid and one of the two isomers of citral (the other being neral). It is a key component of the Nasonov pheromone produced by honey bees and is also found in various essential oils (like lemongrass).
Bees and Geranial: Production and BenefitsÂ
Production:
Honey bees produce geranial as part of the Nasonov pheromone, which is secreted from the Nasonov gland located at the tip of the beeâs abdomen.
Bees fan their wings to disperse the scent into the air.
Functions/Benefits to Bees:
Colony Cohesion: Helps guide foraging bees back to the hive or swarm cluster.
Swarming Behavior: Used during swarming to recruit and regroup bees.
Orientation: Guides disoriented bees or new foragers to resources or hive locations.
Communication: Works in tandem with other chemicals in the Nasonov blend to coordinate social behavior.
Geranialâs Effects on Mosquitoes and Biting Flies
Â
Adverse Effects:
Repellent Action: Geranial is highly repellent to many biting insects including mosquitoes and biting flies.
It interferes with their olfactory receptors, preventing them from locating hosts or resting sites.
Found in many natural insect repellents (e.g., lemongrass oil, citronella).
Behavioral Disruption: Can inhibit feeding and deter landings on humans or animals.
Mechanism:
Affects the olfactory system of mosquitoes, which rely on carbon dioxide and other scents to locate hosts.
May overload or block their scent receptors, causing disorientation or avoidance behavior.
Comparison Summary.
| Aspect | Bees | Mosquitoes & Biting Flies |
|---|---|---|
| Source of Geranial | Produced by bees via Nasonov gland | Not produced; encountered in environment (repellents) |
| Function | Attracts and guides other bees | Repels, confuses, and deters feeding behavior |
| Effect | Positive (communication, orientation) | Negative (disorientation, feeding inhibition) |
| Ecological Role | Supports social structure of bee colonies | Natural deterrent and protection for mammals |
| Use in Products | Rarely commercialized from bees; behaviorally important | Widely used in repellents for humans and animals |
Conclusion,Geranial demonstrates an excellent example of chemical ecology, where a compound beneficial to one species (bees) plays a completely opposite role for others (mosquitoes and flies). This dual nature is exploited in human applications, particularly for natural insect repellents that mimic the defensive chemical cues present in nature.
1. Repellent Action
Studies show that geranial acts as a natural repellent to many species of wasps, especially when encountered in high concentrations.
Wasps, like mosquitoes and flies, have highly sensitive olfactory receptors. Geranial can overstimulate or disrupt these receptors, making it difficult for them to:
Locate food sources
Track prey
Communicate effectively within colonies
Territorial Avoidance
Some observations suggest that wasps may avoid areas where geranial is present, possibly due to:
Its unfamiliar or unpleasant scent profile
The association with another insectâs pheromonal territory (e.g., bees)
Comparison Summary.
In experimental or anecdotal cases, applying essential oils containing geranial (like lemongrass oil) near wasp nests:
Caused nest abandonment
Reduced foraging activity
Induced stress behaviors (e.g., erratic flight, hesitation)
| Feature | Honey Bees | Wasps |
|---|---|---|
| Response to Geranial | Attracted (used in Nasonov pheromone) | Repelled or disrupted |
| Function | Social cohesion, guidance | Disorientation, potential aversion |
| Behavioral Role | Recruitment and hive recognition | Territory avoidance, sensory stress |
What Is the Nasonov Gland?
In worker honey bees (Apis mellifera), there’s a special scent gland located on the upper side of their abdomen called the Nasonov gland. When bees raise their abdomen and fan their wings, they release a smell from this gland to help guide other bees. This is especially important when bees are finding a new hive, returning home, or regrouping after being separated.
The Nasonov gland produces a blend of smells (called a pheromone), including:
Geraniol
Nerol
Citral (includes geranial and neral)
Geranic acid
Farnesol
Nerolic acid
Geranial is important because it’s very noticeable and helps bees find their way back to the colony.
Comparison Summary.
Geranial helps bees:
Attract others to a new hive location
Guide foragers back to food or water sources
Bring scattered members of the hive back together
It works like a GPS signal made of scentâhelping bees stay organized and connected.
Why Does This Matter?
Learning about geranial and how bees use it helps us understand how important smell is to bee behavior. Beekeepers even use synthetic versions of this scent to manage swarms and help bees find their hives.
Studying this also gives us insights into how to protect bees and support healthy pollination in gardens, farms, and ecosystems.
1. Geraniol
Mode of Action: Acts primarily as a repellent and contact toxicant.
Effects on Varroa:
Repels mites from bees and brood cells.
Inhibits mite reproduction within brood cells.
Some studies report moderate to high mite mortality when exposed to geraniol in vapor or contact form.
Advantages:
Low toxicity to bees.
Natural and biodegradable.
Delivery methods tested: evaporation, fumigation, or integration in slow-release matrices like essential oil pads or thymol-type delivery systems.
Mode of Action: One of the two isomers of citral (along with neral), geranial is more volatile and generally more active.
Effects on Varroa:
Shows significant fumigant and contact toxicity.
Often more potent than geraniol in terms of direct mite mortality.
Potential Synergy:
When combined with other essential oil components (like thymol, eucalyptol), may exhibit enhanced acaricidal effects.
Geranial helps bees:
Attract others to a new hive location
Guide foragers back to food or water sources
Bring scattered members of the hive back together
It works like a GPS signal made of scentâhelping bees stay organized and connected.
Considerations
Fast Evaporation
These oils are highly volatile, so sustained-release formulations are key to long-term results.Absorption into Hive Materials
Compounds may soak into wax or wood, reducing their effectiveness.No Known Resistance
Mites havenât shown resistance yetâbut rotating treatments is still smart practice.

Mosquitoes Have Six Mouthparts (Not Just One “Stinger”)
When a mosquito bites, it actually uses six different needle-like structures called stylets, not just a single straw.
Two mandibles and two maxillae are like tiny saws that cut through your skin.
One stylet injects saliva (with anticoagulants and mild anesthetics).
The other is a feeding tube that sucks up your blood.
đ§Ș 2. Their Saliva Makes You Itch
Mosquitoes donât just suck bloodâthey spit in you first!
Their saliva contains enzymes that prevent your blood from clotting, but your immune system sees it as an invader and causes itching and swelling.
đ 3. Only Females Biteâand Only for Eggs
Male mosquitoes feed only on nectar.
Females bite because they need the protein from blood to develop their eggs.
đ ïž 4. Their Mouthparts Are Super-Flexible
Mosquitoes can bend and adjust their stylets while probing for a blood vessel. Itâs like a surgical tool with built-in sensors!
𧏠5. They Can Taste With Their Mouthparts
Mosquitoes have chemosensory receptors on their mouthparts that help them “taste” and detect chemicals in your blood, determining whether youâre a good target.
đŠ· 6. They Saw Into Your Skin
The maxillae move back and forth like tiny saw blades, helping them saw into your flesh painlessly (until your body reacts).
đïž 7. Their Proboscis Can Penetrate Clothing
In many cases, the mosquitoâs needle-like stylets can pierce through tight weaves in clothing, especially if it’s thin or stretched.
Honey bees (Apis mellifera) have several specialized glands that produce substances crucial for their survival
1. Hypopharyngeal Glands
Location: In the heads of worker bees.
Function: Produce royal jelly and brood food.
Active in: Nurse bees (young workers, about 5â15 days old).
Interesting fact: These glands shrink when bees become foragers and expand again if they revert to nursing duties.
2. Mandibular Glands
Location: Near the mandibles (jaws).
Function:
In queens: Produce queen pheromones that regulate colony behavior and suppress worker reproduction.
In workers: Help produce brood food and, in older workers, contribute to alarm pheromones.
Notable compound: 9-oxo-2-decenoic acid (9-ODA) â a major queen pheromone.
3. Wax Glands
Location: On the underside of the abdomen (segments 4â7) of worker bees.
Function: Secrete wax used to build comb.
Active in: Middle-aged worker bees (about 12â18 days old).
Fact: Wax is secreted as tiny flakes and manipulated with the legs and mandibles.
4. Nasonov Gland
Location: At the tip of the abdomen in worker bees.
Function: Produces a pheromone used for orientation and recruitment.
Used in: Swarm coordination and guiding nestmates to food or the hive.
5. Dufour’s Gland
Location: Near the sting apparatus in queens and workers.
Function:
In queens: Related to egg-laying.
In workers: May signal egg-laying attempts or help with recognition.
Interaction with: The gland works in tandem with other reproductive signals.
6. Arnhart (Footprint) Glands
Location: In the tarsi (feet) of worker bees and queens.
Function: Secrete a chemical “footprint” that marks surfaces.
Purpose: Used in trail marking and identifying visited flowers or comb cells.
7. Sting-Associated Glands
Include: Acid gland and alkaline gland.
Function: Combine to produce venom.
Venom use: Defense â injected into predators or threats.
Contains: Melittin (a pain-inducing peptide), phospholipase A2, and other toxins.
đ Amazing Facts About Honey Bee Anatomy
1. Three-Part Body Structure
Every honey bee has three main body parts: the head, thorax, and abdomen. Each section plays a critical role in the beeâs daily tasks like flying, feeding, and pollinating.
2. Five Eyes for Enhanced Vision
Yes, honey bees have five eyes! Two large compound eyes help detect motion and color, while three smaller ocelli on top of their head sense light and help with navigation.
3. Sensitive Antennae
Their antennae are packed with sensory organs that detect smells, temperature, and vibrationsâessential tools for communication and finding food.
4. Powerful Wings
Bees have two pairs of wings that beat around 200 times per second, allowing them to fly up to 15 miles per hour while carrying pollen or nectar.
5. Hairy Helpers
Tiny hairs cover their bodies, helping them trap pollen as they move from flower to flower. These hairs also give bees a strong sense of touch and awareness of air movement.
6. Pollen Baskets
On their hind legs, honey bees have special structures called pollen baskets (or corbiculae) that store pollen during foraging trips.
7. Barbed Stinger
Female worker bees have a barbed stinger, which can only be used once. When they sting, the stinger stays behind, which is fatal to the bee but protects the hive.
8. Nectar-Sipping Tongue
Bees use a long, straw-like proboscis to sip nectar from deep inside flowersâa key part of their role as pollinators.
