Response of soybean genotypes against armyworm,Spodoptera liturabased on no-choice test

Abstract

Abstract.Armyworm is important polyphagous pest causing economic losses in many agricultural crops including soybean. In Indonesia, there are no soybean varieties which indicated had a resistance against armyworm. The experiment was conducted in Laboratory of Entomology and Green House of Indonesian Legumes and Tuber Crops Research Institute from March to April 2016. The experiment was arranged using randomized block design with a total of 18 soybean genotypes as a treatment in three replicates. The results showed that the difference of soybean genotypes had a significant effect on the leaf damaged intensity. Based on no-choice test and the leaves damaged intensity compared

Screening of Soybean Germplasm against Spodoptera litura (Fab.) for the Expression of Antixenosis Resistance Through Seasonal Incidence and Dual-feeding Assay

“…Under the biotic stress insect pest solely caused more than 25% yield loss (Harish et al, 2009) and the most destructive insect pests of soybean include a variety of foliage feeders, stem borers, gram pod borer and stink bug. The tobacco armyworm, Spodoptera litura (Fabricius) is a polyphagous pest and known to attack soybean from the early growth up to harvesting time and it is the major defoliating pest and responsible for upto 68% yield loss (Bayu et al, 2017). The larval form of this pest cause severe damage to the soybean crop by defoliating the leaves.…”

Assessment of Soybean Resistance to Leaf-feeding Insect, Spodoptera litura

“…The use of resistant variety to insects pests is a part of integrated pest management with potential benefits i.e. environmentally friendly, may protect pests' natural enemies, can avoid the emergence of resistance or resurgence, and most importantly are easily adopted by the farmers (Bazok et al, 2011;Bayu et al, 2018).…”

“…The assessment of ten soybean lines for resistance to armyworm in Indonesia have obtained a resistant genotype, G511H/Anj-1-4 . Furthermore, the evaluation using no-choice test had obtained nine soybean genotypes which categorized as moderately resistant to armyworm (Bayu et al, 2018). In Brazil, an evaluation on four soybean genotypes to S. eridania obtained Monsoy 8757 cultivar which most influenced by the prolonged larval, pupal and total cycle length.…”
