Compatibility of Bio and Natural Compounds with Trichogramma evanescens (Westwood) for Pieris rapae Management in Cauliflower

The efficacy of a bio compound, Protecto (Bacillus thuringiensis) and botanicals extract (mixture ginger, garlic, hot red pepper extracts aloe vera) either in combination with Trichogramma evanescens releases or alone was evaluated comparison to an insecticide, Uphold 36% SC (Methoxyfenozide/ Spinetoram) on Pieris rapae cauliflower Brassica oleracea. Field experiments were conducted at Atfih District, Giza Governorate, Egypt September 2020 October 2021. Results revealed that, all the tested compounds combined more effective reducing P. population than when used alone. B. thuringiensis caused 96.91% 95.32% reduction larval 2021 respectively while pupal pupation 70.87% 71.59% during these two trials. Similar results observed botanical extracts. Parasitization by T. ranged between 91.95-92.77% plots sprayed bio- natural trials years. Meanwhile, insecticide treatment least (37.85% 47.85% respectively). It could be concluded that integrated for sustainable production Cauliflower.
