Development

Incomplete (hemimetabolous) - egg, young termite larvae or termite nymph, older nymph, worker, soldier, pseudergate, drone, and queen.

Types

Three different types of termites or caste types

reproductive, workers, and soldiers.

Time of year, diet & Pheromone play a role in determining the development pathway. Pheromone regulates caste, attractor communication, trail making & Maintaining, social cohesiveness, etc.

Terminate Eggs

1. Macroscopic, small, white, translucent, and ovoid in shape.
2. Lays in batches of 25-40 eggs, throughout her life span.
3. Lay 10-20 eggs in the first batch, until the first batch hatches, no second batch of eggs.
4. Oviposition rate increases as queen ages up to 1000 to 30000 eggs/day
5. Hatch: 1-3 months of incubation

Soldier Termite

1. 10-15% population within a colony
2. Develop from either nymphs, pseudergates, or workers
3. Undergo two moults - pre-soldier > soldier
4. Big size with a strong sclerotized head and powerful mandibles.
5. Two types- Mandibulate and Nasute
6. Protection of nest
7. Secretes repellent fluid
8. Viscid secretion is emitted through the frontal pore.
9. Soldiers defended the colony against predatory enemies such as ants, etc.

Reproductives

1. Alates > Pairing> dealates> Mate> New colony
2. Primary reproductives - Alates
3. Neotenics- Supplementary reproductives
4. Alates: winged, weak fliers/flutters, diurnal, attracted to illumination.
5. Travel 200-300 mts. for food and mate, shed their wings "dealates"
6. Pseudergates- Secondary reproductives, develops from adultoids, Nympoids, or ergatoids.
7. Pseudergates: no aerial life, body less sclerotized and pigmented than primary reproductives.
8. Straw color/greyish white, compound eyes reduced, wing growth inhibited to wing pad.

1. 90% of the population within a colony
2. Pale-coloured, wingless, hardened head & mouthparts, head downwards and wider than reproductive caste, resemble nymph, compound eye absent. Body covered with a soft exoskeleton.
3. Mandibles resemble reproductive caste, are more powerful, and are adapted for gnawing wood, etc. thorax similar to soldiers.
4. Dimorphic in nature: Minor form and Major form
5. Function: caring for eggs, and young ones, feeding all the dependent castes viz; larvae, nymph, soldiers, reproductive, forage for food from the distance, excavating galleries, and tunnels, mound building/constructing termitarium, protecting the colony in the absence of soldier.

Alates are the winged reproductive that swarm out from the nest and establish new colonies. Males and females pair off and look for a suitable environment to mate. They are often confused with ant swarmers.

1.There are 1-3 queens in a colony
2. 10-20 eggs are laid in the first batch, and no second batch till the first batch hatches.
3. The oviposition rate increases as she ages, can lay 1000 to 30000 eggs/day
4. The Gravid queen's abdomen is enlarged physogastric and relatively immobile.
5. Secretes pheromone to attract the king
6. Size varies, measures up to 10 cm in length, attains weight up to 35-40 gms
7. Groomed and fed by worker térmites

1. Passageways
2. Defensive mechanism
3. Forage of food
4. Prevent air movement to avoid desiccation
5. Composed secretions. of soil particles, fecal material, glue secretions
6. Prefer sandy soil over clay

Termite Colony

Most termites construct underground colonies rather than mounds, made with soil.

Termitorium: varies in size among different species, heights vary from 7-8 mts, Size and population vary, population size varies from few hundred to million Broadly divided into three main categories:
1. Subterranean - Completely below ground
2. Epigeal - Protruding above the soil surface
3. Arboreal - Built above ground but. connected to the ground by shelter tubes.
4. Function - Defence, Shelter Predator

Four types of shelter tubes are built:

1. Working tubes from the soil to wooden structures, often -crossing barriers such as concrete or stone foundations.
2. Exploratory and migratory tubes arise from the soil but do not connect to wooden structures.
3. Drop tubes extending from wooden structures back to the soil
4. Swarm tubes for new alates to fly out of daring swarming.
