| description | Arhopalus syriacus is an exotic longhorn beetle that attacks mainly Pinus and is present in pine forests of Argentina. The objective of this study was to estimate development and survival of A. syriacus at 25 °C on an artificial diet. Developmental time, developmental rates, pupal weights, larval length, and head capsule widths were recorded in laboratory conditions whereas emergency time of adults, sex ratio and female reproduction were studied using pine logs. Larvae pupated after 6, 7, 8 and 9 stadia. Head-capsule width and larval length decreased from the fourth and sixth instar respectively. Female pupae were heavier than male ones and this situation was the same for pupal length. Survival was lower in the first two instars but increased to 100% in all mature larvae and pupae. The maximum abundances of adults from pine logs occurred in November and December. Male adults lived 9.27 ± 0.84 days and female 9.12 ± 1.61 days. Female adults were heavier than males and the number of new larvae per female was 80.65 ± 10.62. The life cycle duration of A. syriacus was 298.86 ± 13.66 days. |

Arhopalus syriacus es una especie exótica presente en los pinares de Argentina que ataca especies de Pinus. El objetivo de este trabajo fue determinar el tiempo de desarrollo y la supervivencia de A. syriacus a 25 °C usando dieta artificial. Tiempos, tasas de desarrollo, pesos, medidas de cápsulas cefálicas y largo de las larvas fueron observados en condiciones de laboratorio; mientras que la proporción de sexos, emergencia y reproducción de los adultos se registraron utilizando trozas de pinos. Las larvas puparon después de 6, 7, 8 y 9 estadios. El ancho de las cápsulas cefálicas y el largo de las larvas disminuyeron a partir del cuarto y sexto estadio, respectivamente. Las pupas hembra fueron más grandes y pesadas. La supervivencia fue menor en los primeros dos estadios y llegó al 100% en larvas maduras y pupas. Las máximas abundancias de adultos que emergieron de las trozas de pino ocurrieron en los meses de noviembre y diciembre. Los machos adultos vivieron 9,27 ± 0,84 días y fueron más livianos que las hembras, que vivieron 9,12 ± 1,61 días. El número de larvas por hembra fue 80,65 ± 10,62. El ciclo de vida total de A. syriacus duró 298,86 ± 13,66 días.
