The aim of this study was to evaluate the insecticidal effect of aqueous, alcoholic, and oil extracts from leaves of eight medicinal plants against Diabrotica speciosa prepared at five concentrations. The extracts that used commercial soybean oil as solvent showed the highest D. speciosa mortality due to the solvent itself, regardless of the used plants and their concentrations. Thus, commercial soybean oil was discarded as solvent since at these volumes it would cause serious phytotoxicity problems. After 24 hours of exposure of the pest to the extracts, the highest D. speciosa mortality values were observed for Copaifera langsdorfii and Chenopodium ambrosioides extracts, both in 5% alcohol, and Artemisia verlotorum, in 10% water. However, in the last mortality assessment (48 h), C. langsdorfii extract in 5% alcohol showed higher mortality of this pest, followed by C. ambrosioides extract in 5% alcohol, compared to the remaining plants.

Abstract The secondary metabolism products of plants have influenced great economic interest, given their chemical diversity and biological activities. Because of this, this study evaluates the phytochemical composition, antimicrobial activity, insecticidal, and antioxidant activity of plant extracts and oil of Myrcia oblongata. Saponins, steroids, triterpenoids, tannins, and flavonoids were detected. The extracts showed antimicrobial capacity on the tested microorganisms, except for the methanolic extract, which showed no activity for P. mirabilis and S. enteritidis. Regarding the analysis of antioxidant compounds, the hexanic, ethyl acetate and acetone extracts showed higher antioxidant activities and also higher insecticidal performance on Alphitobius diaperinus larvae, resulting in 80% adult mortality. The results reported here show that there may be a relationship between antioxidant potential and the insecticidal effect of Myrcia oblongata DC. The components present in both the extract and the oil can be used as natural alternative to synthetic compounds in the biological control of parasites and pathogenic microorganisms.

Tuta absoluta Meyrick (Lepidoptera: Gelehiidae) is a significant tomato pest, and chemical pesticides are used extensively for its control. Because of the adverse effects of chemical pesticides, researchers have been paying attention more to biopesticides. In this study, the larvicidal effects of the extracts of Tanacetum vulgare (Asteracea), Aleo vera (L.) and (Liliaceae) Tagetes patula L. (Asteracea) was determined and trials were conducted by using leaf dipping and pot methods. The leaf dipping method was conducted in a climate chamber, whereas the potting experiment was performed in the greenhouse. In all of the experiments, second-stage larvae were used to determine the larvicidal effects. According to the results obtained, the highest larvicidal effect and mortality rate was observed at the highest concentration of T. vulgare extract (86%, effect: 86.55%). The lowest mortality rate and the larvicidal effect was observed at the same concentration of T. patula extract (mortality: 79%, effect: 78.55%). In the pot experiment, the highest yield was seen in the Neem Azal T/S, followed by T. vulgare, A. vera and T. patula extracts. On the first day counts, the lowest insecticidal effect was obtained with the lowest concentration of T. patula extract. The extract of A. vera, T. vulgare and T. patula was effective in experiments carried out in pot and laboratory conditions on T. absoluta. It is suggested that more research be done on using these extracts as a biopesticide to control T. absoluta. Keywords: Tomato leaf miner, plant extracts, larvacidal effect.

Abstract Background: The emergence and spread of resistant strains of malaria vectors to chemical insecticides are becoming major problem for malaria vector management. Natural plant products play a vital role to resolve the current challenge of malaria control.Objective: The current study was conducted to evaluate insecticidal effect of ethnobotanical plant extracts against the primary malaria vector, Anopheles arabiensis in Northwestern Ethiopia.Methods: Primarily, ethnobotanical plants used for Anopheles mosquito control was surveyed in Dangur district, Northwestern Ethiopia. Insecticide susceptible strains of Anopheles arabiensis mosquito were reared in insectary of tropical and infectious diseases research center, Assosa university. The larvicidal and adulticidal potentials of frequently used plant extracts against susceptible strains of laboratory colony were evaluated.Result: A total of fifteen plants were identified as ethnobotanical plants helping the local people for mosquito control. Azadirachta indica, Ocimum lamiifolium, Ocimum americanum, Moringa olifiera leaf, and Moringa olifiera seed species of local plants were found to be frequently used to kill and/or repel mosquitoes in the study district. All the plant extracts were found to have potential larvicidal activity against 4th instar larvae of An. arabiensis and only ethanol and methanol extract of A. indica and O. lamiifolium were found to have potential adulticidal effect against adult of An. arabiensis. The highest larvicidal activity was observed in ethanol extract of A. indica with 95% larval mortality and lowest LC50 of 40.73 ppm and LC90 of 186.66 ppm. The highest adulticidal activity was observed in methanol extract of A. indica with 75% adult mortality at 300 ppm and lowest LC50 of 106.65ppm and LC90 of 1293ppm. The lowest larvicidal and adulticidal activity was observed in methanol extracts of O. lamiifolium with 63.35% larval mortality and leaf extract of M. olifiera with 50% adult mortality at 300 ppm, respectively.Conclusion: ethanol extract of A. indica exerted a remarkable larvicidal effect against An. arabiensis and thus it can be used for botanical mosquito insecticide development.
