Linking life table and consumption rate of the fall armyworm, Spodoptera frugiperda reared on different maize cultivars
The life table and leaf consumption data of the fall armyworm (FAW) (Spodoptera frugiperda) reared on three cultivated maize varieties, sweet maize (SMJ), waxy maize (WMJ), and silage maize (SMT) were collected and analyzed using the age-stage, two-sex life table procedure. The highest net consumption rate (C 0), net reproductive rate (R 0), intrinsic rate of increase (r), finite rate of increase (λ), and finite consumption rate (ω) were observed on SMJ (C 0 = 155 cm2, R 0 = 211.1 offspring, r = 0.1494 d-1, λ = 1.1611 d-1, and ω = 2.809). The lowest population parameter values were observed on SMT (C 0 = 122 cm2, R 0 = 135.5 offspring, r = 0.1336 d-1, λ = 1.1429 d-1, and ω = 2.625). The instar-net consumption rates can be described using geometric regression with a 3-fold increase rate from one stage to the next. Because the susceptibility of maize plants to pest damage varies with their growth stage, it is necessary to set separate economic thresholds for pest management at the seedling, bell, and heading stages. In this study, we demonstrated that the life table data, stage-specific leaf consumption, and stage structure could be successfully integrated using computer simulation to obtain optimal timing of pest management procedures. Consolidating these separate data sets is crucial in formulating a sound ecological and economic integrated pest management strategy to control S. frugiperda.
期刊介绍:
Its scope covers all aspects of basic and applied research dealing with insects and more broadly with arthropods inhabiting wild, agricultural and/or urban habitats. The journal also considers research integrating various disciplines and issues within the broad field of entomology and ecology.
Entomologia Generalis publishes high quality research articles on advances in knowledge on the ecology and biology of arthropods, as well as on their importance for key ecosystems services, e.g. as biological control and pollination. The journal devotes special attention to contributions providing significant advances (i) on the fundamental knowledge and on sustainable control strategies of arthropod pests (including of stored products) and vectors of diseases, (ii) on the biology and ecology of beneficial arthropods, (iii) on the spread and impact of invasive pests, and (iv) on potential side effects of pest management methods.
Entomologia Generalis welcomes review articles on significant developments in the field of entomology. These are usually invited by the editorial board, but proposals may be sent to the Editor-in-Chief for preliminary assessment by the editorial board before formal submission to the journal. The journal also considers comments on papers published in Entomologia Generalis, as well as short notes on topics that are of broader interest.
