Arthropod Predators

Abstract Predator-prey interactions form the core of biological control of arthropod pests. Which tools can be used to monitor and collect carnivorous arthropods in natural habitats and targeted crops? Eco-friendly and effective field lures are urgently needed. In this research, we carried out olfactometer experiments assess innate positive chemotaxis to pollen of seven crop and banker plant by two important predatory biological control agents: the coccinellid Propylea japonica (Thunberg) and the anthocorid Orius sauteri (Poppius). We compared the attractiveness of pollens from crops and banker plants to that of common prey homogenates (aphids and thrips, respectively). Attractiveness of the tested odor sources was checked via field trapping experiments conducted in organic apple orchards and by release-recapture assays in organic greenhouse tomato crops. Maize and canola pollen were attractive to both P. japonica and O. sauteri, in laboratory and field assays. P. japonica was highly attracted by balm mint pollen, whereas O. sauteri was attracted by alfalfa pollen. Our results encourage the use of pollen from crops and banker plants as low-cost and eco-friendly attractors to enhance the monitoring and attraction of arthropod predators in biological control programs.

The available controlling agents for mosquito vectors are chemical insecticides and the frequent usage of these insecticides creating resistance among mosquito vectors and environmental pollutions. Thus, the study was designed to synthesize and characterize the Ag nanoparticles (AgNPs) through a methanol leaf extract of Ocimum canum and find the larvicidal prospective of the AgNPs on the 4th instar larvae of Anopheles stephensi, Culex quinquefasciatus, and Aedes aegypti. The obtained outcomes show that the methanol leaf extract of O. canum was effectively reduced the silver ions and produce constant silver nanoparticles. It was characterized and confirmed by various scientific techniques such as UV-vis spectrum, XRD, SEM, FT-IR and EDaX. Various concentrations (10, 50, 150, 200, and 250 ppm) of characterized nanoparticles were tested for larvicidal activity. The premier larval death was observed at 24 h of treatment on A. aegypti with LC50= 17.03 ppm, followed by C. quinquefasciatus with LC50= 14.89 ppm of methanol extract of O. canum and no death was noticed on A. stephensi. The LD90 value for A. aegypti and C. quinquefasciatus were 24.18 & 20.65 ppm respectively. Hence, the Ag nanoparticles produced from methanol leaf extract of O. canum retains efficiency to control A. aegypti and C. quinquefasciatus. Thus, it might support partially to replace the chemical insecticide which used against these vectors and might contribute to reduce environmental pollution.

Abstract Fabrication and use of nanoparticles have progressively enlarged within the last decade. Herein the silver nanoparticles (AgNps) were synthesized via the extract from Marsilea quadrifolia (Mq) as a decreasing and steadying mediator. The Mq-AgNPs demonstrated superior toxicity on Zika virus vector, Aedes aegypti with the LC50 value of 10.69 µg·mL−1. The Mq-AgNPs were established securely to non-target organisms Artemia nauplii and Ceriodaphnia cornuta, and no structural or anatomical alterations confirm its security to the surroundings. The antibacterial activity exposed that Mq-AgNPs showed superior growth inhibition effect against the tested bacteria. Furthermore, the Mq-AgNPs showed strong antioxidant activities when compared to Mq leaf extract. Overall, our results highlight that Mq-AgNPs are hopeful and biodegradable devices against mosquito vectors of therapeutic significance, with moderate toxicity against non-target aquatic animals.

Mosquitoes are one of the most medically significant groups of vectors, having an ability to transmit parasites and pathogens that can have devastating impacts on humans. The development of reliable and ecofriendly processes for the synthesis of metallic nanoparticles is an important step in the field of application of nanotechnology. In this study, we address the biosynthesis of silver nanoparticles (AgNPs) using <em>Leucas</em> <em>aspera</em> leaf extract, and evaluate its lethal concentration (LC<sub>50</sub> and LC<sub>90</sub>) values against first to fourth instar larvae and pupae of the mosquito vectors, <em>Aedes</em> <em>aegypti</em> and <em>Anopheles</em> <em>stephensi</em>. The nanoparticles were characterized by UV-Vis spectrum, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Fourier-transformed infrared spectroscopy analysis. Larvae and pupae were exposed to varying concentrations of aqueous extracts of synthesized AgNPs for 24 h. The maximum mortality was observed from synthesized AgNPs, with LC<sub>50</sub> values for I-IV instars and pupae ranging from 13.06 to 25.54, and LC<sub>90</sub> values ranging from 24.11 to 47.34 for <em>A. aegypti</em>; for <em>A. stephensi</em>, the corresponding LC<sub>50</sub> values ranged from 12.45 to 22.26, and the LC<sub>90</sub> values ranged from 23.50 to 42.95. With methanol leaf extract of <em>L. aspera</em> against <em>A. aegypti</em>, the LC<sub>50</sub> values ranged from 174.89 to 462.96 and the LC<sub>90</sub> values ranged from 488.16 to 963.74; for <em>A. stephensi</em>, the corresponding LC<sub>50</sub> values ranged from 148.93 to 417.07 and the LC<sub>90</sub> values ranged from 449.72 to 912.94. The study suggests that nanoparticles could be a preferred alternative to the most hazardous existing chemical pesticides, contributing to a more healthy environment by providing an ideal ecological and user-friendly vector control strategy for managing malaria and dengue, and contributing to their eventual elimination in the near future.

Cancer is one of the most prevalent diseases in the world and requires new therapies for its treatment. In this context, the biosynthesis of silver nanoparticles (AgNPs) has been developed to treat different types of tumors. The Annona muricata plant is known for having anticancer activity. Its main compounds present in the leaves, stems and skin, allowing for its use as reducing agents. In this manuscript, AgNPs with leaf extract (AgNPs-LE) and fruit peel extract (AgNPs-PE) of A. muricata were biosynthesized obtaining an average nanoparticle diameter sizes smaller than 50 nm, being 19.63 ± 3.7 nm and 16.56 ± 4.1 nm, and with a surface plasmonic resonance (SPR) at 447 and 448 nm, respectively. The lactone functional group present in the LE and PE extracts was identified by the FTIR technique. The behavior and antiproliferation activity of AgNPs-LE and AgNPs-PE were evaluated in breast, colon and melanoma cancer cell lines. Our results showed that Annona muricata fruit peel, which is a waste product, has an antitumor effect more potent than leaf extract. This difference is maintained with AgNPs where the destruction of cancer cells was, for the first time, achieved using concentrations that do not exceed 3 μg/mL with a better therapeutic index in the different tumor strains. In conclusion, we present a low-cost one-step experimental setup to generate AgNPs-PE whose in-vitro biocompatibility and powerful therapeutic effect make it a very attractive tool worth exploiting.
