SIT luck

When medfly ladies lay eggs in ripe fruit the standard of goods can also be impacted, making them inedible and undeserving to be offered.

To keep watch over the outbreak, Mexico designed and applied an emergency motion plan with the help of FAO/IAEA mavens, delivered during the IAEA technical cooperation programme.

Scientists launched greater than 1,450 million sterile male flies in Colima with the environmentally-friendly SIT insect pest keep watch over means, that makes use of irradiation to sterilize bugs.

When the men mated with wild ladies after their Retreat, no offspring had been produced – ultimately resulting in eradication of the bugs.

In cooperation with FAO, the sector’s 2nd biggest Mediterranean fruit fly facility opened previous this 12 months with IAEA attribute in Mexico’s Chiapas state on its southeastern border with Guatemala.

It’s the second one biggest on the earth with a manufacturing capability of one billion flies a week to lend a hand stay the rustic’s rising agriculture pest unfastened.

It makes a speciality of mass manufacturing of sterile bugs and, at the side of the El Pino facility in Guatemala, helps Forsake the containment barrier that forestalls the creation and unfold of the pest to northern Guatemala, Mexico, and the USA.

The IAEA will proceed helping and dealing at the side of Mexico via Acquaintance and regional technical cooperation initiatives, and thru its National Fruit Fly Programme, an IAEA Collaborating Centre.
