“…At 12.0% dose level all plant extracts showed the highest repellency rate and were in repellency F. vulgare. This support previous finding on the other research projects (Mohanny et al, 2020;Ahmed et al, 2020;Ali et al, 2019;Aly et al, 2019). Also , Pierattini et al (2019) evaluated the effect of hexane of essential oil of Pistacia lentiscus, Ocimum basilicum and Foeniculum vulgare against Sitophilus granarius.…”

Acetone and petroleum ether seed extracts of fennel [Foeniclum vulgare, Apiaceae] and arugula seeds [Eruca vesicaria, Brassicaceae] were tested for their contact and stomach poison activity on adults the granary weevil Sitophilus granarius Linnaeus. (Coleoptera: Curculionidae) and lesser grain borer Rhyzopertha dominica Fabricius. (Coleoptera: Bostrochidae). The results revealed that, percentage of mortality increased with increasing the concentration of different extracts and exposure time. Extracts of arugula seeds of petroleum ether and acetone gave higher mortality percent compared with the extracts from fennel seeds. Petroleum ether and acetone extract of arugula seeds was founded to be the higher effect on the two species insect than the fennel seeds extracts. The LC50 of arugula seed extracts of petroleum ether and acetone ranged from 0.722, 0.620, 0.622 and 0.475 ml/ kg after 5 days treatment against R. dominica and S. granarius, respectively. On the other hand, these values of fennel seeds extract ranged from 1.331, 0.798, 1.093 and 0.662 for R. dominica and S. granarius, Respectively. While the higher concentration 1.5 and 2 % (W/V) give complete mortality at two extracts against two insects. The petroleum ether of fennel seeds extract with R. dominica give 73.3 and 83.3 % after 14 days treatment. The inhibition rates in the reduction of the first generation (F1-progeny) of R. dominica and S. granarius adults in grains treated with various extracts were higher than mortality at all concentrations to all extract.

“…We conclude that the biocides used in this study had a highly significant impact on the percentage of mortality of the third instar larvae of the TLM, and thus its effect will be reflected on the population density of the pest in the future, and that the effect of these biocides increases with the increase in concentration and reading after treatment, and Spinosad showed high efficiency compared to other biocides. This agrees with what [28] found in evaluating the effectiveness of spinosad against the larval instars of TLM under laboratory conditions, it was effective and caused mortality of a large proportion of the larvae after 24 hours of treatment and the mean percentage of mortality increased gradually with the days after treatment. Laboratory study of [29] in Bulgaria showed that the biocides Azadirachtin, spinosad and B. thuringiensis var.…”

The experiment was conducted in the Entomology Laboratory/Plant Protection Department/College of Agriculture and Forestry/Mosul University/Iraq in the year 2021, to evaluated the toxicity of biocides, Beauveria bassiana (Bals.) Vuill, (conc. 1, 3, 5 g/L) Bacillus thuringiensis var. kurstaki (conc. 1, 3, 5 g/L), Spinosad (conc. 0.15, 0.30, 0.60 ml/L) and Neem plant extract (Azadirachta indica) (conc. 0.25, 0.50, 1.00 ml/L) on the third larval instar and pupal stage of tomato leafminer (TLM) under laboratory conditions, 25 - 27 °C, and the average relative humidity was 60 - 65%. The results of the study showed that the treatment with Spinosad at a concentration of 0.60 mm/L was significantly superior compared to the rest of the biocides, with an average mortality of 86.67% and 90.67% for larvae and pupae, respectively. All biocides differed significantly compared to the control, which amounted to 0.00%, and the highest mean of larval mortality was 71.67% for the reading after ten days of treatment, which differed significantly compared to the reading after one and three days of treatment, which amounted to 23.89 and 50.56%, respectively. While the reading after nine days of treatment outperformed significantly, and recorded the highest average of pupal mortality, which amounted to 68.00%, compared to the lowest average reading after seven days of treatment, which amounted to 44.00%. The treatment with the biocides B. thuringensis at a concentration of 1, 3 and 5 g/L was superior, with the lowest average percentage of transformation of larva to pupal stage reaching 15.56, 2.22 and 0.00%, respectively, compared to the rest of the concentrations of other biocides and the control, which was 73.33%. The biocides B. thuringensis was significantly superior to the rest of the biocides, and the lowest average percentage of emergence was recorded, as it reached 6.67% in the third concentration 5 g/L, which did not differ significantly compared to the third concentration of the rest of the biocides, however, it differed significantly compared to the rest of the concentrations of other biocides, and the control, as the highest mean of the percentage of emergence rate was 76.67%. It is noted from the study that all biocides had a significant effect on their toxicity to TLM compared to the control, and that the toxicity of biocides for the third larval instar and pupa of TLM increased with increasing concentration and number of days after treatment, and led to a decrease in the average percentage of adult emergence with an increase in concentration used compared to the control. From the results of this study, it is possible to introduce these pesticides in the integrated pest management programs for TLM in open fields and protected cultivation.
