“…Dyes are inactive in the dark and no insect mortalities were recorded in the dark [51]; therefore, sunlight is very important for dye activation. Exposure of a photosensitizer to sunlight as in this study would be more effective and viable than an artificial light source due to the fact that sunlight possesses all wavelengths from UV to visible light [32,35].…”

The control of the camel tick, Hyalomma dromedarii is very crucial. This study evaluated the novel toxicity of photosensitizers and Phoxim insecticide against H. dromedarii males using the adult immersion tests. Ticks were subjected to sunlight for 10 min post-treatment (PT). The optical characters of the applied materials were determined by UV–Vis spectroscopy (250–900 nm wavelengths). The intensity of spectra decreased as dye concentration decreased. The optical bandgap energies of the dyes at different concentrations were not changed as the concentration changed and decreased as the absorption peak of individual dyes red-shifted. The mortalities 72 h PT reached 42.2%, 44.4%, 51.1%, 71.1%, 46.7%, 48.9%, 44.4%, and 55.6% for chlorophyllin, echinochrome, field stain, methylene blue, phthalocyanine, rhodamine 6G, riboflavin, and safranin, respectively. Methylene blue recorded the highest median lethal concentration (LC50 = 127 ppm) followed by safranin, field stain, rhodamine 6G, phthalocyanine, echinochrome riboflavin, and chlorophyllin (LC50 = 209, 251, 271, 303, 324, 332, and 362 ppm, respectively, 72 h PT). Their median lethal time, LT50, values PT with 240 ppm were 45, 87, 96, 72, 129, 115, 131, and 137 h, respectively. The relative toxicities of the LC50 values 72 h PT showed that chlorophyllin, echinochrome, field stain, methylene blue, phthalocyanine, rhodamine 6G, riboflavin, and safranin were 3.2, 3.6, 4.6, 9.1, 3.8, 4.3, 3.5, and 5.6 times, respectively, more effective than Phoxim. Methylene blue, safranin, and field stain showed a broad absorbance area indicating a large photoactivity and better phototoxicity and could be used as alternative agents to synthetic acaricides.

Macroinvertebrate predators such as backswimmers (Heteroptera: Notonectidae), dragonflies (Odonata: Aeshnidae), and predatory diving beetles (Coleoptera: Dytiscidae) naturally inhabit aquatic ecosystems. Some aquatic ecosystems inhabited by these macroinvertebrate predator taxa equally form malaria vector larval habitats. The presence of these predators in malaria vector larval habitats can negatively impact on development, adult body size, fecundity, and longevity of the malaria vectors, which form important determinants of their fitness and future vectorial capacity. These potential negative impacts caused by aquatic macroinvertebrate predators on malaria vectors warrant their consideration as biocontrol agents in an integrated program to combat malaria. However, the use of these macroinvertebrate predators in malaria biocontrol is currently constrained by technical bottlenecks linked to their generalist predatory tendencies and often long life cycles, demanding complex rearing systems. We reviewed the literature on the use of aquatic macroinvertebrate predators for biocontrol of malaria vectors from the An. gambiae s.l. complex. The available information from laboratory and semi-field studies has shown that aquatic macroinvertebrates have the potential to consume large numbers of mosquito larvae and could thus offer an additional approaches in integrated malaria vector management strategies. The growing number of semi-field structures available in East and West Africa provides an opportunity to conduct ecological experimental studies to reconsider the potential of using aquatic macroinvertebrate predators as a biocontrol tool. To achieve a more sustainable approach to controlling malaria vector populations, additional, non-chemical interventions could provide a more sustainable approach, in comparison with the failing chemical control tools, and should be urgently considered for integration with the current mosquito vector control campaigns.

The rising application of conventional synthetic insecticides develops resistant populations of houseflies; therefore, using new chemical agents with different modes of action is essential to overcome this problem. The mechanical grinding technique was used as a green method, to synthesize the tested compounds because it is a more facile work‐up and high‐yield economy, simplicity and solvent‐free than conventional thermal technique. Various methods were employed to synthesize new heterocycles containing anthracene (a photosensitizing agent) from chalcone 3, a building block material such as the preparation of the pyrazole derivatives 4–7, isoxazole derivative 8, pyrimidines 9–11, and oxirane derivative 12. The novel synthesized compounds were analyzed by FT‐IR, 1H‐NMR, 13C‐NMR spectra, and elemental analysis. Herein, the toxicity of the anthracene derivatives was assessed against Musca domestica larvae and adults in different conditions to demonstrate the effect of various inserted moieties on the efficiency of tested compounds. Furthermore, the influence of sunlight on the toxicity of anthracene was studied in dark and sunlight tests against adult houseflies. Moreover, these compounds diminished the total protein and lipids contents while significantly influencing the antioxidant enzymes activities of M. domestica adults. Structure‐activity relationships demonstrated the role of each moiety on the toxicity of compounds.
