Wild Pollinators Found Crucial for India’s Mango Production
A recent study conducted by researchers from India and Germany highlighted the vital role of wild insects in mango pollination. The study found that allowing wild insects to access mango flowers increased fruit yield by 350%, demonstrating their importance in improving mango production.
Highlights
- Wild insect pollination increased mango yield by 350%.
- Important pollinators include:
- Dwarf honey bee (Apis florea)
- Giant honey bee (Apis dorsata)
- Stingless bees (Tetragonula spp.)
- Hoverflies and houseflies
- Native bees were found to be more effective pollinators than non-native bees because they transfer pollen between different orchards.
- Excessive use of neonicotinoid insecticides threatens native pollinators by affecting their navigation, learning, and survival.
- India has recognised pollinators in its Environmental Accounting Framework, assigning them an estimated economic value of ₹2.6 lakh crore (2021–22), equivalent to about 8–10% of the country’s total crop output value.
Emerging Next-Generation Energy Technologies
- Magnetohydrodynamic (MHD) Generator: A power generation technology that converts the kinetic and thermal energy of electrically conducting fluids (such as plasma or ionised gas) directly into electricity without using turbines.
- Casimir Effect: A quantum phenomenon in which two closely spaced conducting plates experience an attractive force due to differences in vacuum energy caused by virtual particles.
- Blue Energy (Salinity Gradient Power/Osmotic Power): A renewable energy technology that generates electricity from the difference in salt concentration between seawater and freshwater using semi-permeable membranes.
Important Days
National Statistics Day – 29 June
The Ministry of Statistics and Programme Implementation (MoSPI) will celebrate the 20th Statistics Day on 29 June 2026 at Dr Ambedkar International Centre, New Delhi. The day is observed annually to commemorate the birth anniversary of Professor Prasanta Chandra Mahalanobis, regarded as the pioneer of modern statistics and economic planning in India.
Highlights
- Statistics Day 2026 will be observed on 29 June.
- Theme for 2026: “Unlocking the Potential of Administrative Data.
Daily Current Affairs Quiz
Q1. Which of the following insecticides commonly used in mango cultivation poses a major threat to native bee pollinators?
A. Bordeaux mixture
B. Neonicotinoid insecticides
C. Sulphur dust
D. Copper oxychloride
Show Answer
Answer: B. Neonicotinoid insecticides
Explanation: Neonicotinoid insecticides are neurotoxic to bees and impair their navigation, learning, memory, and survival, thereby reducing pollination efficiency and mango yield.
Q2. Blue Energy, recently seen in the news, generates electricity by utilising:
A. Temperature difference between the atmosphere and oceans
B. Difference in salt concentration between seawater and freshwater
C. Ocean wave movement
D. Tidal rise and fall
Show Answer
Answer: B. Difference in salt concentration between seawater and freshwater
Explanation: Blue Energy, also known as Salinity Gradient Power or Osmotic Power, generates electricity by harnessing the energy released when freshwater and seawater mix across a semi-permeable membrane.
Q3. What is the theme of Statistics Day 2026 celebrated by the Ministry of Statistics and Programme Implementation (MoSPI)?
A. Data for Digital India
B. Unlocking the Potential of Administrative Data
C. Statistics for Sustainable Growth
D. One Nation, One Data Platform
Show Answer
Answer: B. Unlocking the Potential of Administrative Data
Explanation: The theme for the 20th Statistics Day (2026) is “Unlocking the Potential of Administrative Data”, highlighting the use of administrative data for evidence-based policymaking and governance.
