This summer was hotter than ever, and amidst heat wave warnings that continued day after day, ‘sting warnings’ were issued simultaneously on land and sea. The ‘poisonous snakes of the sea’ jellyfish and ‘the grim reapers of the insect world’ wasps were the main characters in these incidents and accidents. While swarms of jellyfish and wasps were encroaching the entire country with frightening momentum, we meet those who are struggling to protect the peaceful daily lives of the people.
‘Extreme Job’ Fight in the Heat! The Jellyfish and Wasp War episode will air on EBS1TV at 8:55 PM on Saturday, September 5th.
The hot seas bring with them a swarm of venomous jellyfish
Since observations began in 2015, our oceans have been on high alert due to unprecedented attacks by swarms of poisonous jellyfish. In particular, the problem is that the jellyfish are appearing earlier as ocean temperatures rise. Last year, the number of Nomura’s jellyfish was only 0.3 per hectare, but this year, it is said that it has increased by about 360 times to 108 per hectare. Because of the jellyfish that sting with their tentacles just by brushing against them, not only are tourists being stung by the seaside, but fishermen are also suffering enormous damage to their operations! We go inside the site where they are fighting every day to get rid of the swarms of jellyfish that are causing helpless damage.
Wasp-catching ‘bee drone’ and wasp research team tracking the 24 hours of wasps
Another uninvited guest that came with the heat wave, the wasp! The indiscriminate attacks of the longicorn hornet, called the ‘grim reaper of the insect world’, and the ‘bee killer’ black hornet are threatening not only the ecosystem but also our lives. This year, the frequency of wasp appearances has also increased due to the continued heat wave. In particular, since the wasps enter the breeding season from July to September and become very active, most of the bee sting accidents are concentrated at this time. According to the National Fire Agency, the average number of bee sting accidents over the past three years (2021-2023) is 6,213! As of July of this year, there were a whopping 2,815 bee sting accidents, an increase of about 40% compared to previous years. However, the most serious damage is in beekeeping farms where the wasps ‘kidnap’ and ‘murder’ bees every day! In order to prevent damage from the continuous chain of hornets, drones equipped with both ‘corn bullets’ and eco-friendly pesticides have appeared. In addition, we follow the daily lives of a domestic hornet research team that is tracking the ecology of hornets 24 hours a day with American scholars to study ‘ecosystem-disrupting species’ such as black hornets and long-horned hornets, which have emerged as global issues.
