“…Similar agreement with the impact of Streptomyces citreofluorescens mediated nanoparticles tested and obtained LC50 value was 122.6 μL/mL and 60.0 μL/mL against A. stephensi and C. quinquefasciatus (Singh and Prakash 2012). The actinobacterial strains showed most significant activity against A. aegypti and A. stephensi at different concentrations (Balakrishnan et al 2017).…”

Nanomaterials were highly inspired in the field of nanotechnology especially bio synthesized silver nanoparticles (AgNPs) have effectively attracted worldwide that helps to improve in the field of medical science and human health. Actinabacteria mediated nanoparticle were widely used to control insect pests, treatment of antibiotic resistant bacteria, cancer and other diseases due to their potential pharmacological properties compared with other chemical drugs. The present investigation an entomopathogenic actinobacteria Actinokineospora fastidiosa was isolated and synthesis of AgNPs and tested their mosquito larvicidal, antibacterial and anticancer activity. Moreover, the outcome of biosynthesized AgNPs was characterized by UV-visible spectroscopy, X-ray Diffraction (XRD), Fourier transforms infrared spectroscopy (FT-IR), Transmission electron microscope (TEM), scanning electron microscope (SEM) with energy dispersive X-ray spectroscopy (EDX) and zeta potential analysis. The characterized AgNPs showed a potent larvicidal activity against Aedes aegypti, Anopheles stephensi and Culex quinquefasciatus the obtained LC50 values is 9.86 ppm, 8.50 ppm and 8.29 ppm respectively. However, at 25 ppm concentration, AgNPs showed highest ovicidal activity (100 %, 100 % and 97.77 % against A. aegypti, A. stephensi and C. quinquefasciatus respectively) and oviposition deterrence activity was 100 %, 100 % and 98.66 % were achieved against A. aegypti, A. stephensi and C. quinquefasciatus respectively. The enzymes of α, β esterase and Glutathione-S-transferase level were increased due to detoxification process against AgNPs. The histopathological results of AgNPs showed series damage in epithelial cells and brush border cell of mosquito larval gut. In addition, actinobacterial mediated AgNPs was tested against different human pathogenic bacteria. The obtained results showed biosynthesized AgNPs revealed remarkable antibacterial activity against all tested pathogens. The lowest mortality was observed on non-target organisms of Artemia salina at highest concentration of AgNPs. Finally, in vitro toxicity study showed that biosynthesized AgNPs potential anticancer activity and induced reactive oxygen species (ROS) production in human cervical cancer (HeLa) cell line at an inhibitory concentration (IC50) range 42.37 μg/mL. Therefore, it can be concluded that biosynthesized AgNPs using a novel stains Actinokineospora fastidiosa potentially influenced the vector mosquito and bacterial diseases management and pharmacological applications in eco-friendly manner.

“…Synthetic insecticides have been effectively used for the past several decades as a method of vector control. However, the effective use of chemical insecticides has been greatly impeded by several factors such as the development of physiological resistance within the target vector, the causing of environmental pollution resulting in the bio amplification of food chain contamination, and the development of harmful effects on other beneficial non-target animals [13]. Therefore, the need for more effective and environment-friendly control agents has become more urgent and as of the moment, biological agents seem to be the most promising and safest alternative.…”

Bacillus thuringiensis israelensis (Bti) is an effective biological insecticide for killing mosquito larvae. However, choosing the suitable application method for larviciding is critical in increasing its effectiveness. Therefore, this study aimed to determine the effectiveness of Bti (VectoBac®) WG using various applications at high-rise buildings. Three different applications of Bti treatment were applied at three high-rise buildings in Bandar Saujana Putra. The ULV machine is used for Pangsapuri Impian, a mist blower for Pangsapuri Seri Saujana and a pressured sprayer for BSP 21. BSP Skypark does not undergo treatment and acts as a control. The efficacy of Bti treatment was measured by analyzing the ovitrap surveillance data collected (POI and MLT) for pre and post-treatment. Post-treatment ovitrap surveillance indicates that the Aedes sp. mosquito density was lower than the density at the time of pre-treatment surveillance. Overall, the Aedes albopictus species in both an indoor and outdoor environment setting had shown a reduction. The highest Aedes sp. density reduction is seen through the use of mist blowers in outdoor settings for Aedes albopictus, (%POI reduction = 87.4%; %MLT reduction = 93.8%). The mist blower yielded results that is significantly higher compared to other larviciding applications; the order from greatest to the least was mist blower > pressured sprayer > ULV. It can be concluded that each application produces different degrees of effectiveness in reducing the Aedes sp. density in different environmental settings.

“…Following antibiotic susceptibility and primary screening of five actinobacterial stains, next step was the secondary screening. Ethyl acetate extracts were prepared following methods by Vinodhkumar et al (2015) and Balakrishnan et al (2017). Secondary screening was performed following standard agar well diffusion method (Chaudhary et al, 2013).…”
