“…The degree of toxicity in pesticides towards non-target organisms analyzed in this type of study may be related to many factors such as the nature of the formulation and concentration of the products. Another factor that may interfere in the selectivity level is the target host, since for parasitoids of the Trichogramma genre the physical-chemical structure of the core of the egg can be extremely different, which may allow the fixation and penetration of products leading to the rejection of the host (Pratissoli et al, 2011, Oliveira, et al, 2013, Santos et al, 2016, Rodrigues et al, 2017, Deshmukh, et al, 2018, Asrar, et al, 2019, Pratissoli et. al., 2019, Parsaeyan et al, 2020.…”

The aim of this study was to evaluate the possible alterations of biological characteristics of Trichogramma pretiossum (Riley, 1879) (Hymenoptera: Trichogrammatidae) submitted to the parasitism of Anagasta kuehniella (Zeller, 1879) (Lepidoptera: Pyralidae) eggs treated with fungicide registered for the tomato culture in selectivity tests using the methodology suggested by the IOBC/WPRS for selectivity studies. A total of 29 fungicides were evaluated in the experiments performed at the Nucleus for Scientific and Technological Development in Phytosanitary Management (NUDEMAFI). Cards with 20 host eggs were immersed in fungicide syrup and submitted to parasitism for 24 hours. After the incubation period for the parasitoid and their emergence the fungicide effects were assessed for the biological characteristics of the parasitism. We concluded that the fungicides Supera® (COPPER HYDROXIDE 537.4g/L), Nativo® (TEBUCONAZOLE 200g/L + TRIFLOXYSTROBIN 100g/L), Censor® (FENAMIDONE 500g/L), Manzate 800® (MANCOZEB 800g/Kg), Captan SC® (CAPTAN 480g/L), Amistar 500 WG® (AZOXYSTROBIN 500g/Kg), Frowncide 500 SC® (FLUAZINAM 500g/L), Fegatex® (BENZALKONIUM CHLORIDE 100g/L), Redshield 750® (CUPROUS OXIDE 860g/Kg), Proplant® (PROPAMOCARB CHLORIDE 722g/L), Isatalonil 500 SC® (CHLOROTHALONIL 750g/Kg), Recop® (DICOPPER CHLORIDE TRIHYDROXIDE 840g/Kg), Bion 500 WG® (ACIBENZOLAR-S-METHYL 500g/Kg) and Curzate BR® (CYMOXANIL 80g/Kg + MANCOZEB 640g/Kg) presented better results for selectivity in the T. pretiosum parasitoid.

The biological control and use of insecticides need to be compatible in order to preserve the community of insects that is beneficial for the production system. Therefore, the aim of this study was to assess the alterations of biological characteristics of Trichogramma pretiossum Riley, 1879 (Hymenoptera: Trichogrammatidae), when submitted to the parasitism of Anagasta kuehniella eggs (Zeller, 1879) (Lepidoptera: Pyralidae) treated with insecticides recommended for the tomato culture for selectivity tests. The experiment was conducted at the Nucleus for Scientific and Technological Development in Phytosanitary Management (NUDEMAFI) in climate-controlled chambers at the temperature of 15±1ºC, relative humidity of 70±10%, and photophase of 14 hours. One newly emerged T. pretiosum female was used in each Eppendorf tube containing a card with 20 unviable eggs of A. kuehniella host, which were previously emerged in insecticide syrup. Fifteen repetitions were conducted for each treatment. The eggs were submitted to parasitism for 24 hours and after the descendants emerged, the characteristics were verified for biological parasitism and development of individuals. Insecticides with active ingredients Piriproxifen, Teflubenzuron, Acetamiprid 1, Lambda- Cyalothrin and Chlorantraniliprole + Lambda-Cyalothrin were considered the most selective for parasitoid T. pretiosum.

“…Chlorantraniliprole and emamectin benzoate were rated as 'harmless' as per IOBC safety classification whereas spinosad and flubendiamide were found 'slightly harmful' to adults T. Japonicum (Uma et al, 2014). Deshmukh et al (2018) revealed chlorantraniliprole, flubendiamide and azadirachtin as harmless for parasitisation when irradiated host eggs were exposed to T. japonicum. Emamectin benzoate caused 32.50% parasitisation and 56.58% adult emergence of T. chilonis from parasitized host eggs (Singh et al, 2018).…”

Lethal role of some insecticides including one of recent introduction (broflanilide) on Trichgramma japonicum Ashmead (Hymenoptera: Trichogrammatidae) was assessed by exposing its juvenile stages (egg, larva and pupa) inside the host eggs and adults by residual contact. Transgenerational effect was also studied. The results revealed varied level of toxicity among these test methods. Treatment (insecticide) wise overall toxicity was also determined, and insecticides were grouped into different toxicity classes. Chlorantraniliprole and flubendiamide were harmless (< 30% mortality) followed by cyantraniliprole, emamectin benzoate, novaluron + indoxacarb and broflanilide which were harmless to slightly harmful (< 79% mortality). Slightly harmful was teflubenzuron, chlorfenapyr and azadirachtin. Spinosad was slightly harmful to moderately harmful (< 99% mortality).
