How pyrioroxyfen works
Disruption
of metamorphosis:
Pyriproxyfen primarily targets insects during their larval and pupal stages, which are critical periods of growth and metamorphosis. It inhibits the development of adult structures, preventing the insect from reaching sexual maturity and reproducing. This disrupts the insect’s life cycle and reduces its population.
Selective action:
Pyriproxyfen is generally considered to have low toxicity to mammals and birds. It primarily affects insects and is relatively safe for non-target organisms. This selectivity is one of the reasons why pyriproxyfen is widely used in pest management programs.
MICROCAPSULATION
Persistence
and residual effects:
Pyriproxyfen has a long-lasting residual effect.It remains active in the environment for an extended period, which enhances its efficacy in controlling insect populations. This property makes it particularly useful for targeting insects that have a complex life cycle or reside in hard-to-reach areas.
Inhibition of egg production:
Pyriproxyfen also affects female insects by disrupting their ability to produce viable eggs. When exposed to pyriproxyfen, female insects may lay sterile eggs or have reduced egg viability. This further hampers the insect’s ability to reproduce and increases population control.
