Resistance Level of Mung Bean Genotypes to Pod Borer Maruca testulalis Geyer

Abstract

Background: Pod borer, Maruca testulalis is one of the harmful mung bean pests and cause substantial damage to the crop or failure to harvest. This study was carried out to identify the level of resistance to pod borer of mungbean accessions. Methods: Field research was conducted at Muneng Experimental Farm, Probolinggo, East Java, Indonesia in the 2018 dry season using the randomized block design and repeated two times. A total of 50 accessions of mungbeans were planted in two growing environments, namely: L1 = controlled environment (Maruca pest was controlled with NPV biopesticide 2 g/liter of water) and L2 = uncontrolled environment (Maruca pest was not controlled with any kind of pesticide). Observations were made on the intensity of borer attack and dry seed weight. Result: Eleven accessions gave a low resistant (LR) to moderately resistant (MR) categories responses against M. testulalis attacks. The pod damage from the eleven selected accessions was less than 15% under environmental conditions without control (L2). Control application (L1) reduced pod damage by 48.5% and increased mung bean seed yield by 25%, compared to without control (L2). The eleven accessions that were consistent or stable with low attack intensity under conditions with and without control gave dry seed weights above average, except for accessions (MLGV 0054, MLGV 0115 and MLGV 0320) which had dry seed weights lower than the average both in the growing environment with control (L1) or without control (L2).

Arthropods, Pests, and Diseases of Jack Bean (Canavalia Ensiformis) in Upland and Dry Climate Areas

“…The incidence of striped mosaic infection in plants in the vegetative phase is (20 -25%) which is randomly distributed in each plot, while in the generative phase ranges from (39 -47%) in each infected individual (Figure 6). Viral infections in jack beans plants have been reported in several countries including Canavalia mosaic potyvirus in Nigeria [22], Yambean mosaic virus in Brazil [23] and Bean common mosaic virus (BCMV) in Indonesia [24]. Damayanti [26] report the first information of BCMV infection in Indonesia, with characteristic mosaic that have similarities symtomps with this finding in IPPTP Muneng Probolinggo, namely light green and dark green mosaics with clear boundaries, and vein banding.…”

“…This pest is polyphagous with the main host on legumes with yield loss rate can reach 72%. Until now, there have been no resistant varieties of Maruca sp in various plant such as cow pea, mungbean, and long beans [19,20]. Attacks in the pod-filling phase lead to high yield losses of more than 80% [21].…”

Microorganisms secrete viscous and water-absorbing (Jonsson et al, 2009;Wang et al, 2019;Song et al, 2020;Wu et al, 2020;Shen et al, 2021;Erol et al, 2022;Zini et al, 2022) (Costa et al, 2009;Tekin et al, 2017;Kandel et al, 2019;Adamczewska-Sowinska et al, 2021;Colque-Little et al, 2021;Domingos and Bilsborrow, 2022) (Zhao et al, 2010;Ferrazza et al, 2013;Benevenuto et al, 2018;Delin et al, 2018;Kebede et al, 2019;Umina et al, 2020;Jordan-Meille et al, 2021;Li et al, 2022) (Azpilicueta et al, 2012;Fazalova and Nevado, 2020;Abbas et al, 2022;Beniwal et al, 2022;Woo et al, 2022) (Shen et al, 2010;Mehmood et al, 2018;Indiati et al, 2021;Hussain et al, 2022;Mott et al, 2022;Tariq et al, 2022) (Holou and Stevens...…”

“…Pod borer, pod sucker and armyworm caused seed yield losses ranges 79%-100% (Baliadi et al, 2008;Sari and Suharsono, 2011;Motaphale et al, 2016;Marwoto et al, 2017). In mungbean, the 36-75% yield loss was due to pod borer (Umbarkar et al, 2011;Indiati et al, 2021).…”
