“…Fall armyworm (FAW) Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) is a widespread polyphagous invasive pest that attacks maize (Zea mays L.), which is grown as a summer and winter crop all over the world. 1 FAW is highly migratory and can colonize and infest more than 80 different plant species, including grasses and crops such as groundnut, alfalfa, soybean and sorghum; it is most destructive to sweetcorn and vegetable crops. 2 FAW larvae feed mainly on the whorl of the plant and reduce plant vigor.…”

BACKGROUND The fall armyworm (FAW) Spodoptera frugiperda (J. E. Smith), native to the Americas, is a new invasive pest that was reported in India for the first time in May 2018. Being polyphagous, FAW can infest several different hosts and increase its population all year round. In this context, the present study was conducted under laboratory conditions to evaluate the biological parameters of FAW on four different hosts, Zea mays (maize), Gossypium hirsutum (cotton), Ricinus communis (castor) and Brassica oleracea var. botrytis (cauliflower), and a semi‐synthetic diet. RESULTS The shortest life cycle of 32.8 ± 0.52 days in males and 34.1 ± 0.43 days in females was observed on maize. Semi‐synthetic diet was superior in terms of higher mean fecundity (1324.6 ± 61.21 eggs), larval weight (503 ± 0.02 mg), pupal weight (263 ± 0.01 mg) and adult female weight (128 ± 0.0 mg) compared with natural hosts. Cotton was the least preferred host with a longer life cycle of 49.5 ± 0.50 days. Head capsule width and length were measured and the growth rate was validated using Dyar's rule. The mean width and length of the head capsule of first‐instar larvae of FAW on different hosts was 0.35 ± 0.00 mm. The maximum width (2.76 ± 0.03 mm) and length (2.31 ± 0.03 mm) were observed in sixth‐instar larvae grown on diet. CONCLUSION The results of this study will be instrumental in understanding and formulating management strategies for FAW.

“…As reported by Waquil (2008), the fact that pests remain inside the canopy hinders their control due to the lower exposure to the insecticide during the daytime period. Campos et al (2014) found a lower number of Spodoptera frugiperda caterpillars when the application was directed to the crop row, with no difference between the volumes applied, which were 50, 100 and 150 L ha -1 , indicating that the use of these volumes may not interfere in the control of S. frugiperda. In other words, reducing the application rate became feasible when the target was reached with the technology used, in this case the application directed to the crop row.…”

“…After the applications, the water-sensitive paper cards were collected and stored in plastic PVC film to avoid contamination by air moisture. Insecticide coverage was characterized using a scanner, where the water-sensitive papers were scanned (spatial resolution of 600 non-interpolated dpi, with colors in 24 bits) and the images were later processed using the Program Conta-Gotas ® (CANTERI et al, 2001), specific for this purpose.…”

Insecticide Application Speed in the Control of Lepidopteran Pests in Soybean1

et al. 2020

During the chemical control of pests, diseases and weeds, great importance is given to the phytosanitary product and little attention to the application technology. The control of soybean pests did not escape the general rule and, therefore, some pests known as secondary, and even nonexistent, became responsible for great damage to the soybean crop. The objective of this work was to test the application of insecticide at different speeds (5 and 16 km h-1) by varying the rates of application in 108 to 110 and 199 to 216 L ha-1 to quantify the difference in the coverage percentage of the applied insecticide in the canopy of soybean plants, and to verify the interaction of these factors with efficacy parameters for the control of caterpillars (Helicoverpa armigera and Chrysodeixis includens). In general, the highest leaf coverage by the insecticide was observed in the upper part of the canopy, regardless of the rate and speed of application, resulting in lower leaf damage. For the middle and lower thirds of the plant, the decrease in speed influenced more the decrease in leaf damage by the caterpillars than the increase in the spray volume.

It is primarily damaging to sweet corn and vegetable crops, but it also affects other non-host crops (Lewter et al, 2006), hence increasing its host range (Shylesha et al,2018).…”
