“…Similar larval duration is reported by the study conducted by Ahir et al (2020). However, this larval duration is influenced by host type of FAW and prevailing rearing conditions in a laboratory (Dahi et al, 2020). Larval mortality was 70%, 66% and 12% for the I, II and III instars, respectively but zero mortality was recorded in IV, V and VI larval instars.…”

Fall armyworm (FAW) (Spodoptera frugiperda J.E. Smith) is a polyphagous pest, native to North and South America and is invasive in Eurasia and Africa. Life cycle and morphometric studies with the invasive population of FAW in Nepal were conducted under laboratory conditions in Chitwan, Nepal. Gravid females laid an average of 156.25 eggs per egg batch, with an average of 979.43 eggs during their whole lifetime. The average pre-oviposition period was 3.75 days, oviposition period was 3 days, the larval developmental period was 16.31 days, the pupal period was 9.69 days, and the whole life cycle (egg to egg) averaged 33 days. The average length of each instar larva from I to VI instars was 1.5, 3.6, 7.1, 11.6, 18.5, and 34.4 mm, respectively. Head capsule widths for each instar were 0.35, 0.47, 0.8, 1.37, 2.11, and 2.7 mm, respectively for instars first through sixth. Pupal and adult emergence rates were 98.9 and 97.2%, respectively, with a male to female ratio of 1:1.3. Larval mortalities of the I, II, and III instars were 70, 66, and 12%, with no mortality in the IV, V and VI instars. Adult longevity was 20.73 days for males and 22.78 days for females. These findings are useful to design an integrated management protocol of the fall armyworm. SAARC J. Agric., 20(1): 77-86 (2022)

“…The thermal threshold accuracy of the FAW was evaluated based on both the data from this study and its distribution range. Thermal thresholds estimated beyond the ranges of 8.7-15.0 • C for T L , 25.0-35.0 • C for T opt , and 33.0-40.0 • C for T H were considered unrealistic [34][35][36][37]. Models that estimated realistic thermal thresholds for the FAW were preferred to those that estimated unrealistic thermal thresholds.…”

The fall armyworm Spodoptera frugiperda (J.E. Smith) is an economically important pest that recently invaded Africa and Asia; however, information regarding its biological capacity to establish itself in newly invaded environments is largely unknown. We investigated the effects of temperature on the development and survival of the invaded populations of S. frugiperda and selected mathematical models to evaluate its development in a new environment. S. frugiperda exhibited optimum survival and growth at temperatures between 28 °C and 30 °C. The lower and upper thermal thresholds for the egg-to-adult life cycle were 13.51 °C and 34.13 °C, respectively. We compared seven mathematical models and found that the Shi model was the most suitable for describing the temperature-dependent development rate of S. frugiperda. Therefore, the Shi mathematical model may be used to predict both the occurrence of particular developmental stages and the geographic distribution to implement measures for the management of S. frugiperda in agricultural fields.

“…In 2016, it invaded the African continent and its first appearance was in Nigeria, then spread rapidly to more than 28 countries of southern and eastern Africa (Goergen et al, 2016;Day et al, 2017;Cock et al, 2017;FAO, 2018); causing considerable damage to more than 70% of maize yield losses and to a less extent to sorghum and other crops (Baudron, 2019;FAO, 2019). Recently, in May 2019, FAW was firstly recorded on maize fields only in a village of Kom-Ombo city, Aswan Governorate, Upper Egypt as reported by the Agricultural Pesticide Committee (APC), Ministry of Agriculture (Dahi et al, 2020), then spread to Luxor, Qena, and Sohag Governorates. Later, it invaded Assuit Governorate in 2021; causing damage to maize fields.…”
