“…The results obtained in the experiment with D. melacanthus indicated that the activity of Spn LC 50 was similar to that of either the associated or pure Spn LC 25 , and more efficient than the control treatment (Table 3). It is known that Spn may negatively affect the levels of natural enemies (Firake et al, 2017;Hill & Foster, 2000;Liu et al, 2007) and other beneficial insects (Mayes et al, 2003), where we can find some different results (Fernández et al, 2017;Ishaaya et al, 2005;Rimoldi et al, 2012). However, several authors have reported its efficiency in the control of several pests in urban areas (Khan, 2018;Santos et al, 2019;Valcárcel et al, 2015), stored grains (Athanassiou et al, 2008;Vayias et al, 2009), horti-fruticulture (F. Huang & Subramanyam, 2007;Stark et al, 2004), and even of major agricultural pests (Aydin & Gürkan, 2006;Pineda et al, 2007;Wang et al, 2009).…”

Stink bugs are important pests of highly profitable agricultural crops worldwide, and the use of insecticides remains the main strategy for their control. The objectives of this study were to evaluate the behavioral aspects of Euschistus heros and Diceraeus melacanthus through feeding after exposure to chloride solutions (NaCl and KCl), as well as the control efficacy of insecticides in combination with salt. Two bioassays were performed with stink bugs exposed to treated substrate: i) feeding preference by salivary sheath counting in a free choice test for chloride solutions, using bean pod or corn seedling as counting substrate for newly emerged E. heros and D. melacanthus adults, respectively; and ii) comparative efficiency of five synthetic insecticides associated with NaCl or KCl in the mortality of 4th instar nymphs (N4). Pre-determined sublethal (LC25) and median lethal (LC50) concentrations of commercially available insecticides (Lfn), buprofezin (Bpf), pyriproxyfen (Ppx), chlorantraniliprole (Ctn) and spinosad (Spn) were used. For each species and insecticide, the treatments were pure LC25, LC25 + NaCl 5% m/m, LC25 + KCl 5% m/m, pure LC50, and distilled water (dH2O) as the control. Corn seedlings treated with 5% NaCl saline solution had reduced salivary sheaths from D. melacanthus. Ctn LC25 (0.63 mL L-1) + 5% NaCl and pure Ctn LC50 (1.16 mL L-1) were similar and more efficient in terms of mortality of D. melacanthus N4s than any other treatment. The association of Spn LC25 (0.37 mL L-1) + 5% NaCl and Spn LC50 only (0.90 mL L-1) was similar to that of E. heros N4s compared to other treatments. The insecticide concentrations used in this study have potential for stink bug pest control, thus the association of insecticides with commercially available, easy-to-find, and low-cost chloride salts may represent a good strategy for stink bug control.

“…However, although foliar spraying of insecticides can rapidly control the spread of pests in a short time, this approach has a short control duration and low effective utilization of pesticides, and promotes the development of pest resistance 7–9 .

BACKGROUNDMonolepta hieroglyphica (Motschulsky) is an important agricultural pest that causes significant economic losses in terms of crop production. Conventional pesticide spraying treatments can result in pesticide drift, endanger nontarget organisms, and cause pests to fly away, resulting in unsatisfactory prevention and control effects. To study the effect of thiamethoxam on the control of maize M. hieroglyphica, a field experiment was conducted to determine the optimal thiamethoxam application dose, its spatial and temporal distribution dynamics and its dietary risk based on its control effect when applied by spray and drip irrigation.RESULTSThe results of the field trials showed that compared with spray irrigation, drip irrigation resulted in greater control starting from the 5th day. This result was due to the hysteresis effect of thiamethoxam being first absorbed by the roots and then continuously transferred upward, where it accumulates. After 30 days of drip irrigation with 75 and 150 g a.i. ha‐1 thiamethoxam, the control effect on M. hieroglyphica was 32.41‐49.44% and 69.77‐80.57%, respectively. The results of the dietary risk assessment showed that the risk of thiamethoxam ingestion through maize kernels was acceptable regarding its effect on human health.CONCLUSIONSDrip irrigation with thiamethoxam can improve the effective utilization rate of pesticides, achieve precise control of maize M. hieroglyphica, and provide a new method for sustainable agricultural production.This article is protected by copyright.

“…Some of their degradation intermediates, which possess even higher toxicity, have been detected at higher concentrations in drinking water and surface water compared to their parent forms . Pesticides have also been reported to induce harmful physiological responses in many wildlife such as honey bees, , butterflies, and humans. − Health impacts of pesticides include irritation, damage to the nervous and endocrine systems, and carcinogenic effects. , Hence, pesticide removal is vital to protect public health and environmental safety. , …”

Metal Organic Frameworks (MOFs) as Photocatalysts for the Degradation of Agricultural Pollutants in Water

et al. 2021

Increasing demand for food due to rapid population growth has exerted unprecedented pressure on the global agricultural industry. Agrochemicals are widely used to ensure productivity, leading to the prevalence of legacy and emerging agricultural chemicals in the environment, most of which are toxic and persistent. Metal−organic frameworks (MOFs) as a group of novel photocatalytic materials with ultrahigh porosity and tunability have demonstrated high potential for efficient removal of these recalcitrant pollutants. This critical review aims to present the potential of MOF-catalyzed photodegradation of pesticides and antibiotics. Initially, the capabilities of different MOF-based composites to harvest visible light are compared. Examples include MOFs combined with bismuth oxyhalides (BiOX) and graphite oxide (GO). Mechanisms involved in MOF-induced photocatalytic processes such as electron−hole (e − /h + ) separation, generation of reactive species, and degradation pathways of representative pollutants as well as impacts of water chemistry are illustrated in detailed. Research on applying MOF-catalyzed processes is largely in progress, and many more studies with greater mechanistic evaluation are needed to fully assess the potential of such processes to depollute water.
