A serious Mosquito borne yellow fever is one of the grave diseases which affect the major population. Since there is no specific treatment for yellow fever, there is a necessity to develop an effective agent. The series of acridinone analogues 3 to 5 were synthesized with help of non-conventional microwave heating and confirmed by respective spectral characterization. 5c and 3b showed highest activity to kill 90% of larvae against A. aegypti and C. quinquefasciatus, respectively. Also the active products were treated to check the mortality of non-target aquatic species. Through the reports of the larvicidal bioassay, compounds 3b against C. quinquefasciatus whereas 5c against A. aegypti were found to be more active. By keeping this as a platform, further extension of the work can be done to find out a valuable drug for controlling disease vectors.

Small-scale shrimp trawling is crucial for the economy and culture of coastal communities worldwide, providing several ecosystem services. However, bottom trawling is well-known for its negative impacts on habitat structure and marine communities. Bycatch, or the accidental capture of non-target species during fishing, can offer valuable insights into the composition and variation of fish assemblages.

Aquatic herbicides are commonly used to control a variety of non-native plants. One common active ingredient used in commercial herbicide formulations globally is 2,4-dichlorophenoxyacetic acid (2,4-D). Though 2,4-D is used in aquatic ecosystems, no studies have investigated cellular, biochemical, and transcriptional effects or mechanisms of 2,4-D exposure on fathead minnows (Pimephales promelas) throughout juvenile development.

Diquat (DQ) is a non-selective, fast-acting herbicide that is extensively used in aquatic systems. DQ has been registered as the substitute for paraquat due to its lower toxicity. However, the widespread presence of DQ in aquatic systems can pose an ecological burden on aquatic organisms.

Little is known about the potential impact of point source contamination from seed treatment pesticide residues and degradation products in waste products in treated seed. The presence of these pesticides and their degradation products in the environment has been associated with toxic effects on non-target organisms including bees, aquatic organisms and humans. In this study, we investigated the occurrence of twenty-two pesticide residues and their degradation products in two streams receiving runoff from land-applied wet cake, applied and spilled wastewater originating at a biofuels production facility using pesticide-treated seed as a feedstock.

Tenebrio molitor has gained attention as a potential solution for plastic pollution. This study explored the biodegradation of polystyrene (PS) by mealworms co-fed with rice bran (RB) under an optimized rearing scheme. The RB co-diet significantly increased PS consumption by two-fold compared to wheat bran (WB).
