“…Swamy et al (2010) found that Flubendiamide provided good protection and less pod damage among newer insecticides viz., Flubendiamide, Spinosad, and Emamectin benzoate. Grigolli et al (2015) also observed the similar findings in context to management of Maruca vitrata through Flubendiamide in soyabean. Sreekanth and Maha Lakshmi (2012) reported that the percent inflorescence damage due to legume pod borer is the lowest in Spinosad 45% SC @ 73 g a.i/ha treated plots (4.74%) followed by Bacillus thuringiensis @ 1.5 kg/ha (10.52 %) ISSN: 2661-6270 (Print), ISSN: 2661-6289 (Online) DOI: https://doi.org/10.3126/janr.v4i1.33250 which is highest in control (24.79%) in pigeonpea.…”

Cowpea (Vigna unguiculata Walp.) is a major grain legume used as vegetables and pulses. Among the several insect pest of cowpea, spotted pod borer is one of the most destructive pest. To evaluate the available chemical pesticides for pod borer management, a set of field experiments on cowpea variety Malepatan-1 were conducted at Horticulture Research Station, Malepatan, Pokhara in years 2019 and 2020. The experiments were laid out in Completely Randomized Block Design (RCBD) having seven treatments viz.Flubendiamide 39.35 % SC @ 0.3 mL/L, Chlorantraniliprole 18.5 % SC @ 0.2 mL/L, Emamectin benzoate 5 % SG @0.3 g/L, Spinosad 45 % SC @0.3 mL/L, Bacillus thuringiensis Kurstaki @2g/L, Azadirechtin 0.03%@ 5mL/L and Control with four replications. Flubendiamide 39.35 % SC @ 0.3 mL/L and Emamectin benzoate 5 % SG @0.3 g/L were found the most effective insecticides in lowering cowpea flower and pod damage with highest benefit cost ratio; however, considering environment, Chlorantraniliprole 18.5 % SC @ 0.2 mL/L and Spinosad 45 % SC @0.3 mL/L being next effective treatments could be viable option to manage spotted pod borer in cowpea production.

“…Grain yield losses of 50%-71% were reported in pigeon pea and Adzuki bean (Sharma & Franzmann, 2000). In Brazil, M. vitrata is considered as a seasonal pest on soybean (Hoffmann-Campo et al, 2000), and it caused about 56% damage (Grigolli, Lourenção, & Ávila, 2015). Up to 380,000 t of cowpea was lost due to M. vitrata in Malawi, Senegal, Niger, Tanzania, and Kenya (Gressel et al, 2004).…”

Variations in the functional response of legume pod borer (Maruca vitrata) populations to sex pheromone blends were observed in Asia and Africa. Hence, this study was carried out to understand the differences in pheromone‐binding proteins (PBPs) among Maruca populations in Asia, Africa, Oceania, and South America. A de novo transcriptome assembly was adopted to sequence the entire transcribed mRNAs in M. vitrata from Taiwan. The raw‐sequence data were assembled using homologous genes from related organisms in GenBank to detect M. vitrata PBPs (MvitPBPs). Sections of the cDNA of MvitPBP of different length were used to design primers to amplify the full‐length cDNA of PBPs. All three PBP sequences comprised three exons interspersed by two introns. In total, 92 MvitPBP1 haplotypes, 77 MvitPBP2 haplotypes, and 64 MvitPBP3 haplotypes were identified in 105, 98, and 68 Maruca individuals, respectively. High pairwise FST values (0.41–0.73) and phylogenetic analyses distinguished the putative Maruca species in South America from those occurring in rest of the world, and possibly two putative subspecies in Asia and Africa. The haplotype networks and Automatic Barcode Gap Discovery analyses also confirmed these results. The negative Tajima's D and Fu's FS values showed the recent demographic expansion of Maruca populations. Thus, this study confirmed the presence of different Maruca species and/or subspecies in different continents based on the diversity within PBP genes. Additional sampling and studies are suggested for Oceania and South America. The genetic differences among Maruca populations should be carefully considered while using sex pheromone lures and bio‐control agents.

Abstract. In order to reduce the use of insecticide, the application of Beauveria bassiana may be an alternative control. The objective of this study was to evaluate the efficacy of B. bassiana for controlling mungbean pest. The experiment was conducted in Ngale Research Station from February to May 2017, using randomized block design, seven treatments, four replicates. The treatments were frequency of application; P1= six times, P2= five times, P3= four times, P4= three times, P5= once, P6= full protection using chemical insecticide, and P7= no protection. Application of B. bassiana four to six times can suppress the population of Empoasca sp., Riptortus linearis, and Maruca testulalis, but did not significantly different with the application of chemical insecticide. Based on the seed weight, application of B. bassiana six times (659.7 g/plot) led to significantly high as compare with the application of chemical insecticide (374 g/plot). Application of B. bassiana tended to be secure to natural enemies, especially Coccinella sp., Oxyopes javanus, and Paederus fuscipes. Both of those predators were not found on the application of chemical insecticide. Hence, B. bassiana can be recommended as a biological agent in integrated pest management component on mungbean because of effective and environmentally friendly.
