“…Entre as temperaturas de 22°C a 30°C, a sobrevivência larval foi superior a 72,5%, sugerindo que a fase de larva é capaz de se desenvolver com sucesso nessa faixa térmica. Bento et al (2006) verifi caram que larvas de A. subrufella submetidas à temperatura constante de 25°C completaram o desenvolvimento em 14,3 dias, aproximadamente, um dia mais rápido que a duração encontrada neste estudo (15,9 dias) para a mesma temperatura (Fig 1b). De acordo com Panizzi & Parra (1991), a quantidade e a qualidade do alimento consumido na fase larval dos insetos podem afetar, entre outros aspectos, o seu desenvolvimento.…”

“…Contudo, a sobrevivência das pupas não diferiu estatisticamente e variou de 83,3% a 100% nas temperaturas estudadas. A duração dessa fase a 25°C também foi inferior àquela relatada por Bento et al (2006), mas próxima aos valores citados por Bondar (1940). Entretanto, esse último autor não informou as condições ambientais nas quais realizou o estudo.…”

“…Dessa forma, os resultados da fase adulta para os indivíduos mantidos a 18ºC e 32 o C não foram considerados para comparações estatísticas. Na temperatura de 25 o C, considerada ótima para a maioria dos insetos, A. subrufella apresentou a maior fecundidade (Fig 2), com produção superior àquela já relatada (Bento et al 2006). Além de a temperatura de 25 o C ter resultado na maior fecundidade observada de A. subrufella, essa temperatura também foi a única em que todas as fêmeas observadas realizaram postura.…”

“…Estudos realizados visando conhecer a sua biologia em laboratório demonstraram que o inseto completa uma geração a cada 28,5 dias a 25 ± 1 o C (Bento et al 2006). No entanto, não existem estudos sobre o desenvolvimento da praga sob condições variáveis de temperatura, bem como a respeito da determinação de suas exigências térmicas.…”

-Among the important pests of coconut, the coconut moth Atheloca subrufella (Hulst) is a signifi cant pest of fl owers and fruits, and is found across all coconut-producing regions in Brazil. We investigated the thermal requirements of A. subrufella and estimated the number of generations for two different growing coconut regions in Pernambuco State. The developmental time of all immature stages reduced as the temperature increased. The egg to adult period ranged from 19.3 to 59.8 days from 32ºC to 18 o C, respectively. The survival of the period from egg to adult was 25% at extreme temperatures (18 o C and 32 o C), while at the intermediate temperatures it was over 72%. Based on the thermal requirements determined for A. subrufella and the average temperatures determined for "Zona da Mata" and "Sertão" of Pernambuco State, it was estimated that A. subrufella is able to complete up to 13 generations per year in both areas. These results indicate that A. subrufella exhibited development and reproduction limited by temperatures higher than 32 o C and lower than 18 o C. However, based on the thermal requirements of A. subrufella and the mean temperatures of the "Zona da Mata" and "Sertão" of Pernambuco State, this pest can develop throughout the entire year.

“…A longevidade média de fêmeas de A. subrufela variou de 12,2 a 14,9 dias, resultados próximos aos 15,2 dias encontrados por Bento et al (2006). Portanto, a longevidade de adultos de A. subrufella não foi afetada pela densidade de larvas criadas por fruto.…”

Rearing Technique and Biological Traits of Atheloca subrufella (Hulst) (Lepidoptera: Phyci dae) in Coconut Fruits.Larvae of the coconut moth Atheloca subrufella (Hulst) develop in lowers and fruits of coconut, Cocos nucifera, causing precocious abscission of these structures and, hence, yield decrease. This work studied a feasible and suitable rearing technique for A. subrufella using fruits of coconut. We irst determined the appropriate density of larvae to be reared per coconut fruit (among two, three, four or ive larvae) and later tested the suitability of this rearing technique for three successive generations. The storage of egg and pupal stages during 0, 5, 10 and 20 days was also studied at 12 o C. Based on the fertility life table parameters, the best results were achieved by rearing two or three larvae per fruit as they yielded the best net reproductive rate and intrinsic rate of population increase. In addition, eggs and pupae of A. subrufella can be stored at 12 o C up to ive days with viability higher than 90%. Adult moths emerged from pupae stored for ive days at 12 o C produced an average of 219.4 eggs and lived 18.8 days. Storage periods for eggs and pupae over 10 days signi icantly reduced egg viability and adult fecundity, respectively. Thus, the technique in here described was shown to be suitable for the continuous rearing of A. subrufella in laboratory conditions.

The fall armyworm (FAW) Spodoptera frugiperda (J. E. Smith) is an economically important pest that is native to the tropical and subtropical regions of the Americas, where it is well known as a key pest of corn (Barfield et al., 1978;Garcia et al., 2018;Sparks, 1979). The FAW cannot survive the winter in temperate North America because it cannot enter a diapause. The regions in the United States in which FAW overwinters are southern Florida and southern Texas (Barfield et al., 1978;Johnson, 1987). The moth is a sporadic and long-distant
