SUMMARY:

Chemical control is the preferred method used for the key tomato pest Neoleucinodes elegantalis, however its efficiency has not been satisfactory and its indiscriminate use has caused an increase in production costs. Essential oils appear as a promising alternative and their association with biological control, such as the use of the parasitoid Trichogramma pretiosum, can enhance its results, being an option to be considered. Thus, this research aimed to analyze the effects of Origanum majorana and Copaifera officinalis oils on the physiology of N. elegantalis through the histology and histochemistry of the gonads, comparing with commercial formulated products (azadirachtin and deltamethrin) and the effect of the association of essential oils of Amyris balsamifera and Pelargonium graveolens with T. pretiosum, through biology and functional response and its toxicity to the pest, in comparison with the formulated products azadirachtin and deltamethrin, in addition to chromatography of the aforementioned oils. All tested oils were mostly made up of terpenes. O. majorana oil presented greater toxicity compared to C. officinalis and demonstrated better performance by altering important parameters in the physiology and histochemistry of the gonads of this pest, causing a reduction in yolk and total proteins in the ovarioles; and in the testicles, reduction of sperm, carbohydrates and proteins. For the combination of methods, P. graveolens oil with T. pretiosum was the one that showed the best results, with greater toxicity to the pest. For the parasitoid, this oil appeared, in terms of selectivity, to be slightly harmful, not compromising its performance, in addition to promoting a type II functional response. Therefore, the use of oils and their association with T. pretiosum to control N. elegantalis becomes an interesting tool in IPM programs, as long as the particularities that guide this interaction are observed.
