Study Notes
Excretion and Anatomy of Insects
- Excretion occurs via green glands or Malpighian tubules.
- Insects typically exhibit sexual dimorphism with separate sexes.
- Internal fertilization and developmental metamorphosis characterized insect reproduction.
- Class: Insecta (Hexapoda) - air-breathing, predominantly terrestrial, some aerial, rarely aquatic.
- Body division into three main parts: head, thorax, and abdomen.
- Head features various mouthparts for chewing, biting, piercing, sucking, siphoning, or sponging.
- Thorax consists of segments with a pair of jointed legs and two pairs of wings.
- Abdomen composed of 7-11 segments; respiration facilitated by tracheae.
Sub-class Pterygota and Division Endopterygota
- Sub-class Pterygota: wings typically present; abdomen lacks appendages except for genitalia and cerci.
- Metamorphosis can be simple or complex.
- Division Endopterygota: wings develop internally and undergo complete metamorphosis, including a pupal stage.
Order Hymenoptera
- Characterized by social and parasitic insects.
- Modified mouthparts for biting and sucking; two pairs of wings with reduced veins.
- Defense mechanisms primarily through stings; workers possess stings, while drones do not.
- Queen honey bee has a vestigial sting.
- Larvae are legless (apodus) with exarate pupae (legs not appressed).
Honey Bees: A Historical Perspective
- Honey bees have been associated with humans since prehistoric times, documented in ancient texts like the Vedas, Ramayana, and Quran.
- Their significance in ancient civilizations is reflected in art, coins, and burial sites.
- Used strategically in warfare, honey bee swarms historically hindered enemy movements during WWI in Belgium.
- Bee venom recognized for its medicinal properties, aiding in pain relief and treatment for rheumatism and arthritis.
Beekeeping Development
- Primitive beekeeping methods have existed globally; advancements began with the movable frame hive invented in 1851 by Rev. L.L. Langstroth.
- Introduction of modern beekeeping to India occurred in Bengal (1882) and Punjab (1883).
- Systematic beekeeping initiatives began in Pusa, Delhi (1907-1919), expanding to the South in 1911.
- By 1928, the Royal Commission on Agriculture recommended beekeeping development as a cottage industry, promoting its growth in India.
Systematic Classification of Honey Bees
- Phylum: Arthropoda - includes jointed-legged, segmented animals with a chitinous exoskeleton.
- Open blood vascular system; respiration via gills, tracheae, or book lungs.
- Super-family: Apoidea - encompasses social bees and caste differentiation; female antennae have 12 segments, males 13.
- Family: Apidae - moderate-sized bees, with females collecting pollen in specialized baskets.
- Sub-family: Apinae - minute to moderate-sized bees living in large eusocial colonies.
- Tribe: Apini - true or stinging honey bees, including species introduced globally.
Honey Bee Species
- Genus: Apis - includes notable species such as A. dorsata, A. florea, and A. cerana indica.
- A. dorsata produces the highest honey yield among Indian species.
- A. indica (Indian Hive Bee) prefers dark nesting sites and is adapted to artificial hives.
- A. florea (Little Bee) builds small combs in open areas and has a limited altitude range.
Honey Bees' Habits and Habitat
- Highly organized social insects, active year-round but exhibit limited activity in winter.
- Springtime is crucial for brood rearing and honey collection.
- Colonies communicate through sign language and exhibit polymorphism.
- Major honey-producing species, like Sarang bees, yield significant quantities of honey (up to 25 kg per comb) and support extensive pollination efforts.
- A. indica is adaptable for beekeeping; A. florea remains more spontaneous in nesting behavior.
