“…Based on reported trapping studies it was expected that commercial lures for S. frugiperda from North America and England would contain Z9-14Ac and Z7-12Ac or all five acetates found in the effluvium found from S. frugiperda in North America 9 . Analysis of S. frugiperda lures from North American and English sources yielded Z9-14Ac and Z11-16Ac in ratios varying from 80 : 20 to 85 : 15.…”

“…Addition of Z,E,9,12-14Ac and Z7-12Ac or E9-12Ac to Z9-12Ac decreased capture rates 11,12 while addition of 2% Z11-16Ac or Z9-14Ac to Z9-12Ac did not alter capture rates 10 . Superior attraction was reported to lures containing Z9-14Ac and Z7-12Ac in a ratio of 99.4 : 0.6 and to the five acetates in the effluvium of S. frugiperda from North America at their natural ratios 9 .…”

A captura em massa da Spodoptera frugiperda (Smith) na América Central requer um atrativo altamente eficiente e com consistência na taxa de captura. Atrativos empregados para S. frugiperda provenientes da América do Norte e Inglaterra apresentaram taxas de captura irregulares quando aplicados no campo. A reinvestigação de quatro acetatos (Z9-14Ac, Z11-16Ac, Z7-12Ac e Z9-12Ac) para S. frugiperda encontrada na Costa Rica revelou que Z7-12Ac e Z9-12Ac, quando empregados de maneira isolada, se mostraram altamente atraentes. Combinação binária de Z7-12Ac e Z9-14Ac aumentou consideravelmente o poder de atração sendo, no mínimo, dez vezes mais atraentes à S. frugiperda da Costa Rica que os atrativos provenietes da América do Norte e Inglaterra. A adição de Z11-16Ac à combinações binárias de Z9-14Ac e Z7-12Ac , causou um pequeno aumento nas taxas de captura. Quando a concentração de Z7-12Ac é aumentada para 5% em atrativos contendo Z9-14Ac, Z11-16Ac e Z7-12Ac as taxas de captura diminuem significativamente. O atrativo otimizado contém Z7-12Ac que é um composto não descrito anteriormente para S. frugiperda da região caribenha.Mass trapping of Spodoptera frugiperda (Smith) in Central America required a high performance lure with consistent capture rates. S. frugiperda lures from North America and England gave erratic capture rates under field conditions. A reinvestigation of four acetate attractants (Z9-14Ac, Z11-16Ac, Z7-12Ac and Z9-12Ac) for S. frugiperda present in Costa Rica revealed that Z7-12Ac and Z9-12Ac were highly attractive to S. frugiperda when presented alone. Binary combination of Z7-12Ac with Z9-14Ac significantly increased attraction and was at least 10 times more attractive to S. frugiperda in Costa Rica than North American or English lures. Addition of Z11-16Ac to binary combinations of Z9-14Ac and Z7-12Ac marginally increased capture rates. If the concentration of Z7-12Ac is increased to 5% in lures containing Z9-14Ac, Z11-16Ac and Z7-12Ac capture rates significantly decrease. The optimized lure contains Z7-12Ac that is a component not previously reported in S. frugiperda from the Caribbean region.

“…[3][4][5] Particularly useful has been the pheromone composition reported by Tumlinson et al (1986) as a mixture of (Z)-9-tetradecen-1-yl acetate (Z9-14 : Ac), (Z)-7-dodecen-1-yl acetate, (Z)-9-dodecen-1-yl acetate, and (Z)-11-hexadecen-1-yl acetate in 81 : 0.5 : 0.5 : 18 ratio. This formulation has been very effective in controlling populations of S. frugiperda in the USA and the Caribbean basin.…”

Inhibition of electrophysiological response to the pheromone of the fall armyworm, Spodoptera frugiperda

In the search for new control methods for the fall armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae), we present the inhibition of the electroantennographic (EAG) response to the pheromone by 3-octylthio-1,1,1-trifluoropropan-2-one (OTFP). As a member of the trifluoromethyl ketones, OTFP is a potent inhibitor of serine esterases, particularly those of insect antennae. Exposure of antennal receptors to OTFP vapors resulted in a decreased amplitude and 2/3 repolarization time (2/3 RT) of the EAG response to the pheromone. The effect was reversible, with the amplitude and repolarization time being recovered upon suppression of the treatment. The non-fluorinated analogue 3-octhylthiopropan-2-one (OTP) did not affect either the amplitude or the 2/3 RT of the EAG response to the pheromone, confirming the key role played by fluorine atoms in this type of chemical. These results may be the basis for new behavioral studies with the aim of considering OTFP in future management strategies of the FAW.

The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is a globally significant agricultural pest, causing severe damage to corn production in China. Chemical odor‐based trapping is a major approach for FAW control, making it essential to understand the FAW antennal sensillum types to enhance development of effective chemical odor attractants. In this study, we comprehensively examined the antennal sensilla types of FAW, identifying eight types and two subtypes, including Böhm's bristles, sensilla trichoidea, sensilla chaetica (I and II), sensilla coeloconica, sensilla styloconica, sensilla squamiformia (I and II), sensilla auricillica, and sensilla basiconica. Sensilla chaetica II, and sensilla squamiformia II are reported for the first time for FAW in this study. Detailed low‐voltage field emission scanning electron microscope (LVSEM) images and descriptions are provided for each sensillum type. This study provides the morphological information to aid in conducting antennal sensillum neurophysiological tests on FAW.Research Highlights The types of sensilla of fall armyworm were examined, identifying eight types and two subtypes, including Böhm's bristles, sensilla trichoidea, sensilla chaetica (I and II), sensilla coeloconica, sensilla styloconica, sensilla squamiformia (I and II), sensilla auricillica, and sensilla basiconica.
