In October,2023,agricultural officials in California discovered three Mediterraneanfruit flies,or Medflies for short,in the Leimert Park neighborhood of Los Angeles.
Medflies are one of the most serious threats faced by farmers worldwide.The flies lay
their eggs in over 300 kinds of fruits and vegetables.When the eggs hatch,they turn intoworm-like larvae that can ruin the produce.The problem is that it can be difficult to knowthat the flies are there until it's too late.The fruits and vegetables still look normal even afterthe eggs are laid inside.So the damaged fruits and vegetables can be sent to other places,allowing Medflies to spread.
The first Medfly was detected in California in 1975,but it wasn't until between 1980and 1982 that the flies reached outbreak levels.There were doubts about the government'sability to control them.Then-governor Jerry Brown authorized a campaign spreading theinsecticide called Malathion to knock out the flies.Californians claimed that the chemicalbeing spread across their neighborhoods could kill the flies,but surely it could affect theirhealth negatively.The state declared the flies were controlled in 1982.California stopped thecampaign in 1990.
After the three were discovered in October,the government set up a 233-square-kilometer special area.This means that no produce(fruits,nuts,or vegetables)can bemoved out of that area.That may seem extreme,since only three Medflies were found,butexperts believe there're probably more out there."It's really important to get on top of thisfast,or growers would go out of business,"said one of the experts.
Luckily,California has developed a program to control Medflies.The program involvesusing planes to drop millions of male Medflies over the area.All of them have been treated sothat they can't help occasion new Medflies.The males are sterile,which means that eventhough they can mate with female Medflies,the resulting eggs will never grow and are sosmall that they don't affect crops.
