The prepupal and pupal stages [...] to remain in the shaded areas on the plant. The eggs are white and banana-shaped and are inserted singly in plant tissue by the females. The early larval [...] symptoms The black tea thrips feeds primarily on the foliage of ornamental plants. It attacks the lower surface first and, as feeding progresses and the population

Akanthomyces muscarius

This process is often facilitated by the production [...] weakens the pests, eventually leading to their death. Additionally, the fungus produces enzymes and toxins that further contribute to the demise of the pests [...] muscarium The efficacy of Lecanicillium muscarium depends on temperature and relative humidity conditions inside the crop canopy and the timing of application
