“…The development of more competitive moths may improve the effectiveness of AW-IPM programs integrated with SIT technique [46,47]. Species-specific nature and compatibility with existing control methods (biological control, mating disruption, cultural control, and use of biorational pesticides) make SIT an indispensable part of AW-IPM application and also make it superior to other control methods [48][49][50]. There are a number of successful models in terms of integrating the SIT in AW-IPM programs against many important lepidopteran pests [51,52].…”

Pesticides are often considered a suitable solution for controlling pests. However, the use of chemicals is very costly, and their residues have always the potential to pollute soil, air, and ground water and also pose significant risks to the natural ecosystems and nontarget organisms. Considering all these, irradiation could offer substantial and charming option for eliminating the export commodity fumigation uses for the undesirable effects of chemicals. Gamma rays, high-energy electrons, and X-rays are among the ionizing radiation sources utilized practically in sterile insect releasing programs using self-contained and non-self-contained or panoramic irradiators.When applying radiation sources, dosimetry should be adjusted to ensure quarantine security for large groups of insect pests. "ecause of growing concerns related to health problems and environmental pollutions, chemical sanitizing treatments are faced with a lot of regulatory restrictions, so irradiation reveals best choice for this purpose.The sterile insect technique SIT may have indispensable consideration for integrated pest management IPM of many important insect pests, including agricultural, veterinary, and medicinal importance. On the other hand, to overcome the obstacles of SIT treatments, genetic engineering techniques were supposed to ease the development of transgenic insects for sustainable tactics to control pest populations. Thus, genetic means should be an integral part of SIT treatments in controlling important pest populations.

The field trial was conducted in Central Research Farm (CRF) at SHUATS, Prayagraj, during Kharif-2021-22. The experiment was laid out in RBD (Randomized Block Design) and replicated thrice with seven treatments. Viz., T1 Indoxacarb 14.5%EC, T2 Flubendiamide 39.5%SC, T3 Emamectin benzoate 5%SG, T4 Bacillus thuringiensis 5% WP, T5 Spinosad 45% SC, T6 Neem oil 4%, T7 Chlorantraniliprole 18.5%SC, (T8) untreated Control was tested to compare the percent fruit infestation against Helicoverpa armigera and their influences on yield of Tomato. The lowest fruit infestation and best economical treatment were recorded in Spinosad 45 SC followed by Indoxacarb 14.5% SC, Chlorantraniliprole 18.5% SC, Emamectin benzoate 5% SG, Flubendiamide 39.5% SC, Bacillus thuringenesis 5% WP Neem oil 4% and as compared to control T8. The highest yield was obtained in Spinosad 45SC (260q/ha) followed by Indoxacarb 14.5%SC (245q/ha), Chlorantraniliprole 18.5% SC (225q/ha), Emamectin benzoate 5%SG (200q/ha) Flubendiamide 39.5% SC (185q/ha), Bacillus thuringenesis 5% WP (163q/ha) Neem oil 4% (149q/ha) and as compared to control T8 (80q/ha). After calculating the benefit-cost ratio of different treatments highest B: C ratio of different treatments was observed for Spinosad 45SC (1:8.8) followed by Indoxacarb 14.5% SC (1:8.3), Chlorantraniliprole18.5% SC (1:7.6), Neem oil (1:7.2), Emamectin benzoate 5% SG (1:6.8), Flubendiamide 39.5% SC (1:6.3), Bacillus thuringenesis (1:5.6), as compared to control T8 (1:2.8) having the lowest B: C ratio.

BACKGROUND Azadirachtin has the potential to be used for pest control. Nevertheless, few studies have investigated the effects of azadirachtin on the cognitive behavior of pests. In this study, expression of the cAMP response element‐binding protein (CREB) and its gene were studied via a series of experiments in Spodoptera litura larvae treated with azadirachtin. RESULTS RNA‐Seq analysis of S. litura larvae treated with azadirachtin was undertaken. According to Kyoto Encyclopedia of Genes and Genomes analysis, the top 20 enriched pathways included neuroactive ligand–receptor interaction pathways, with seven significantly differentially expressed genes including CREB. Quantitative real time polymerase chain reaction (qRT‐PCR) results indicated that the CREB gene was expressed during all developmental stages of S. litura, but relative expression of the CREB gene was significantly downregulated after treatment with azadirachtin. Grayscale statistical analysis also showed that expression levels of protein kinase A (PKA), extracellular signal‐regulated kinase (ERK) and CREB proteins were significantly downregulated after treatment with azadirachtin. Moreover, RNA interference results showed that the effect of azadirachtin on the cognitive behavior of S. litura was consistent with that seen after interfering with CREB. In addition, larval selectivity to addictive odor sources was reduced, and the initial reaction time was increased. CONCLUSIONS This study clarified that azadirachtin can affect the cognitive behavior of S. litura and treatment with azadirachtin resulted in a downregulation of gene and protein expression of CREB and its pathway proteins. © 2020 Society of Chemical Industry
