1. Sterile Insect
Techniques
(SIT)

3. Sterile Insect Technique - SIT
The sterile insect technique (SIT) is a method of
biological insect control, whereby overwhelming
numbers of sterile insects are released into the
wild
The sterile males compete with wild males to
mate with the females.
Females that mate with a sterile male
produce no offspring, thus reducing the next
generation's population.
Sterile insects are not self-replicating and,
therefore, cannot become established in the
environment.

4. “precision-guided sterile insect
technique," or pgSIT,
This is a schematic of the new precision-guided sterile insect
technique (pgSIT), which uses components of the CRISPR/Cas9
system to disrupt key genes that control female viability and
male fertility, resulting in sterile male progeny.

5. What is a Sterile Insect?

7. The global annual market for insecticides is projected to reach
$19.27 billion by 2022, according to Statista
A new strain of genetically engineered moth
that wipes out its crop-ravaging cousins by
preventing them from breeding has been
released into the wild in New York state.
The diamondback moth (Plutella xylostella)
causes billions of dollars of damage to crops of
the brassica genus, including cabbage, broccoli
and cauliflower.
But the new strain, developed with help from
Oxfordshire-based biotech company Oxitec, is
genetically engineered to prevent its female
caterpillar offspring from surviving.
Using the new moths, researchers from Cornell
University successfully suppressed a population
of diamondbacks in New York state, while
preventing insecticide resistance from
developing.
The project paves the way for effective and
sustainable pest control that is more
environmentally friendly and at a much lower
cost than insecticides, according to the
researchers.
