“…Two percent of Tween 80 was added as an emulsifier. The formed emulsion was sonicated during 30 min using ultrasonic cleaner set, model WUC-DO3H 290W and 60 Hz, then sonicated for 1min using a high energy ultra sonication probe model VCX750, 750W, 20 kHz, and resonicated 30 min by the ultrasonic cleaner under cooling conditions using ice path according to Yousef, Dalia A. et al [17].…”

Nanotechnology is considered to be a development way to gain efficient and potential approaches towards pest control. The effect of both neem and peppermint oils as bulk, nano and loaded nano-emulsions have been studied against the different biological aspects of the 2 nd larval instar of Agrotis ipsilon (Hufn.) under laboratory conditions. Their effects on enzymatic activities were investigated for the 2 nd and 4 th larval instars. The effects of adding the different formulations of either neem or peppermint oils to artificial diet of 2 nd instar larvae show significant elongation of the larval duration; percentage mortalities were increased as well as larval malformations. It was recorded that nano-formulations (emulsion or loaded) significantly decreased the pupal weight and significantly increased the pupal duration, percentage pupal mortalities and pupal malformation. Adult longevity show insignificant effect, while female fecundity and percentage egg fertility show significant decrease in comparison with the control. Results of enzymatic activities show marked effects of the three formulations of either neem or peppermint oil. Significant inhibitions were recorded for amylase, invertase, trehalase, protease and alkaline phosphatase. However, significant increase in the activities of cuticle phenoloxidase and chitinase were recorded. Marked variations were recorded between nano-formulations and the bulk form.

“…In the same vein, Meriga et al (2012) The essential oil may impact insect development and metabolism (Moutassem et al, 2021). However, EOs causes reduced food ingestion (Roel et al, 2010), inhibits digestive enzymes (Yousef et al, 2018) and can result in prolongation of the development duration. Previously research showed that essential oil caused impaired feeding performance and inactivation of digestive (Bezzar-Bendjazia et al, 2017).…”

Essential oils (EOs) from plants can provide an eco-friendly alternatives to traditional synthetic insecticides. This study aimed to evaluate the effects of six different essential oil (Foeniculum vulgare, Cinnamomum verum, Allium sativum, Capsicum annum, Mentha piperita, Urtica dioica) against Musca domestica. Larvicidal and pupicidal, efficacy of six EOs were evaluated by contact toxicity method at four different doses (1%; 2.5%, 5%, and 10%) in 5 replications. The research was performed at 60 ± 1.5% humidity and 27 ± 0.5 0C temperature at the Animal Physiology Laboratory of Ondokuz Mayıs University. The LC50 and LC90 values were determined by probit analysis. The effects of treatment and concentrations on different exposure periods, larval and pupal survival and development time were analyzed by a two-way analysis of variance. The larval toxicity of six EOs increased significantly with increased exposed periods. The larval and pupal mortality percent was also increased as the concentration increased for testing all essential oil. The highest larval mortality percent (100.0%) was observed at the (10%) concentration of six essential oils, and all concentrations of Cinnamomum verum oil. Besides, the lowest larval mortality percent (46%) was caused by the 1% concentration of Foeniculum vulgare. The highest pupicidal effect was shown by 10, 5, 2.5% Cinnamomum verum EOs (100% mortality) and 1% Cinnamomum verum EOs (97.36%). The present study revealed that tested essential oil had significant potential for affecting biological parameters of M. domestica. The Cinnamomum verum EOs can be used as an eco- friendly product for the control of housefly larvae and pupae.

“…Nano-emulsions were created according to Youssef et al (2018) and Jerobin et al (2012). Essential oils were combined with distilled water (at a ratio of 1:2) after that Tween 80(2 percent) was added at a rate of 1 milliliter/liter.…”

In Egypt, tomato crop is the second most important vegetable crop and Tuta absoluta comes among the most serious lepidopterous insects that attaching the tomato crop. Due to the dangers of chemical pesticides, nanoemulsions have recently been in pest control programs. The present study looked into the larvicidal activity of the three plant oil extracts and their nano-emulsions against the second instar larvae of T. absoluta. Spraying method was used for application on the leaves infested with T. absoluta larvae. Results showed that nano-emulsions of essential oils were more effective than traditional essential oils against larvae. The highest mortality proportion caused by the high concentrations of Nano emulsion of essential oils (250 ppm) and essential oils (10000 ppm) under laboratory conditions. But the highest reduction percentage in larvae population was caused by essential oil nano-emulsions under field conditions. As a conclusion, nanoparticles of essential oil have to be used as biopesticides in IPM programs of T. absoluta.
