“…The botanicals insecticides should be less toxic than synthetic insecticides, such as the thymol being 50 times less toxic to bees than the dimethoate 10 . The T. vulgaris oil also is promising for integrated pest management with T. pretiosum 43 . The natural insecticide azadirachtin was less toxic than the imidacloprid to Partamona helleri Friese, 1900 and Scaptotrigona xanthotricha Moure 1950 (Hymenoptera: Apidae) at field doses 46 .…”

the toxicity of essential oils that can be used in insect pest management to pollinators needs further studies. Apis mellifera Linnaeus and Trigona hyalinata (Lepeletier) (Hymenoptera: Apidae) foragers were exposed by three pathways to ginger, mint, oregano and thyme essential oils to provide their Lc 50, LD 50 and Lc 90, LD 90 . oregano and thyme were more toxic through contact and topically for A. mellifera while the toxicity of mint and ginger was lower. Trigona hyalinata was more tolerant to the essential oils than A. mellifera. in the walking test, the area was treated (totally or partially) with sub-doses (Lc 50 ) obtained via contact. the area fully treated with oregano reduced the distance traveled and the movement speed increased the number of stops by A. mellifera. Similar results were observed for T. hyalinata with oregano and thyme oils. Apis mellifera showed irritability remaining shorter time in the area partially treated with ginger, mint and thyme essential oils while T. hyalinata had similar behavior with ginger and thyme. essential oils did not repel A. mellifera or T. hyalinata, but those of ginger, mint and thyme reduced the time spent by A. mellifera in areas treated with sublethal doses. oregano and thyme essential oils reduced the survival, mainly, of A. mellifera, while ginger and mint were selective for both pollinators.Bees are essential for plant propagation 1 , but factors such as pathogens, habitat losses and intensive pesticide use are reducing their populations 2 . The decline of bee colonies, known as Colony Collapse Disorder (CCD), threatens pollination and the production of honey, propolis, royal jelly, and wax 3,4 . Bees are exposed to insecticides during the pollen and nectar harvesting through contact with the treated plant surface and the ingestion of sap from seeds coated with systemic insecticides 5,6 abamectin, acetamiprid, cartap-hydrochloride, chlorfenapyr, deltamethrin and thiamethoxam were toxic to Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae) workers by direct spraying; diet treated and contact with pulverized leaves 2 . Larvae mortality was high and adult mobility of Melipona quadrifasciata Lepeletier, 1836 (Hymenoptera: Apidae) low with diet treated with imidacloprid 7 . These insecticides act on arthropods, causing physiological and behavioral effects by directly interfering in the acetylcholine receptors 7 . In addition, insecticides may affect learning, foraging, growth, besides pupa malformation, adult emergence and reproduction 8,9 and caused irritability and repelled bees 7 . Residues in wax, nectar and pollen reduce the quality and value of these products 4 .The vulnerability of A. mellifera to pesticides has been studied 2,10 but the effect of these products on native stingless bees such as Trigona hyalinata (Lepeletier) (Hymenoptera: Apidae) is little understood. The development period of stingless bees is generally longer than that of Apis spp., and, therefore, their survival is more under

“…Non-target effects on T. evanescens could thus have both economical and ecological consequences. Regarding EOs, some Trichogramma species are sensitive to contact (Parreira et al, 2018a,b, 2019; Alcántara-de la Cruz et al, 2021) or fumigant (Poorjavad et al, 2014) toxicity. Brief immersion of host eggs in diluted EO drastically reduce parasitism by Trichogramma wasps (Parreira et al, 2019; Alcántara-de la Cruz et al, 2021).…”

“…Brief immersion of host eggs in diluted EO drastically reduce parasitism by Trichogramma wasps (Parreira et al, 2019; Alcántara-de la Cruz et al, 2021). Moreover, exposition of parasitized host eggs to EOs might reduce parasitoid emergence, longevity and fecundity and affect their progeny (Poorjavad et al, 2014; Parreira et al, 2018a,b, 2019; Alcántara-de la Cruz et al, 2021). EO fumigation increases adult mortality and affects mating and oviposition behavior (Poorjavad et al, 2014).…”

Essential oils (EOs) are increasingly used as biopesticides due to their insecticidal potential. This study addresses their non-target effects on a biological control agent: the egg parasitoid Trichogramma evanescens. In particular, we tested whether EOs affected parasitoid fitness either directly, by decreasing pre-imaginal survival, or indirectly, by disrupting parasitoids' orientation abilities. The effect of Anise, Fennel, Sweet orange, Basil, Coriander, Oregano, Peppermint, Mugwort, Rosemary and Thyme EOs were studied on five strains of T. evanescens. Specific experimental setups were developed, and data obtained from image analysis were interpreted with phenomenological models fitted with Bayesian inference. Results highlight the fumigant toxicity of EOs on parasitoid development. Anise, Fennel, Basil, Coriander, Oregano, Peppermint and Thyme EOs are particularly toxic and drastically reduce the emergence rate of T. evanescens. Most EOs also affect parasitoid behavior: (i) Basil, Coriander, Oregano, Peppermint, Mugwort and Thyme EOs are highly repellent for naive female parasitoids; (ii) Anise and Fennel EOs can have repellent to attractive effects depending on strains; and (iii) Sweet orange, Oregano and Rosemary EOs have no detectable impact on orientation behavior. This study shows that EOs fumigation have non-target effects on egg parasitoids. This highlights the need to cautiously precise the deployment framework of biopesticides in an agroecological perspective.
