Benefits

Efficacy

Invader-B-Lok contains a highly specific natural attractant targeting several species of fruit fly, particularly those in the genus Bactrocera.

Residues

The product leaves no residues on fruit, allowing it to be used right up to harvest without any withholding restrictions.

IPM Friendly

Fully compatible with Integrated Pest Management (IPM) programmes, Invader-B-Lok supports sustainable pest control strategies.

Specificity

Invader-B-Lok is environmentally safe, posing no harm to fish, birds, or wildlife, and has minimal impact on beneficial insects.

How does it work?

Invader-B-Lok uses the Male Annihilation Technique (MAT), which targets male fruit flies that respond to methyl eugenol. By eradicating males, mating opportunities are reduced, leading to a significant decline in population levels and lower fruit infestation rates.

Efficacy & Trial Data:

Invader-B-Lok has been developed for the control of Oriental Fruit Fly across a wide range of agricultural crops.

  • Benin Trials (in collaboration with Citrus Research International, CRI):
    Trials using methyl eugenol and mercaptothion-impregnated blocks resulted in a substantial reduction in male fruit fly numbers, significantly lowering mango infestation and increasing marketable yields.
  • Nelspruit Trials (2-year period):
    Applications of 10–12 blocks per hectare performed significantly better than 4 blocks/ha in reducing fruit fly infestation on Star Ruby grapefruit.

Trial findings confirm Invader-B-Lok as a highly effective and environmentally responsible tool for suppressing Oriental Fruit Fly populations and protecting fruit quality.
