Title A name given to the resource Population fluctuation of Sternechus subsignatus Boheman (Coleoptera: Curculionidae) at its different development stages associated with soybean crop cycle in Tucumán, Argentina Fluctuación poblacional de Sternechus subsignatus Boheman (Coleoptera: Curculionidae) en sus diferentes estados de desarrollo asociados con el ciclo del cultivo de soja en Tucumán, R. Argentina Creator An entity primarily responsible for making the resource Eduardo Willink, M. Guillermina Socías, Augusto S. Casmuz, D. Gustavo Zaia, Lucas E. Cazado, Gerardo Gastaminza Description An account of the resource Soybean stalk weevil Sternechus subsignatus Boheman 1836 (Coleoptera: Curculionidae) population fluctuation was assessed during a three-year period in Northwestern Argentina (NOA). Both population fluctuation of adults, eggs and active larvae on soybean [Glycine max (L) Merr] host plants, as well as overwintering forms in soil (larvae, pupae and adults), were recorded. S. subsignatus is a univoltine species, so its life cycle is annual and comprises an active phase, when the pest attacks soybean crops and another dormancy phase, when it remains buried in the soil. Adults were first observed in the crop from late November up to early March. From then onwards, S. subsignatus development stages where it remained associated with the host plant took place at definite times. The eggs appeared on plants from mid-January to the end of March. Larval period lasted from the end of January to the end of April, when larvae jumped onto the ground and buried themselves to spend the winter. Pupae were observed towards the end of September, and adults first appeared as October was drawing to a close. A new cicle began, with adults emerging in late November or early December. Thus, it was observed that S. subsignatus in the NOA region presents a single annual generation.La dinámica poblacional del picudo del tallo de la soja Sternechus subsignatus Boheman 1836 (Coleoptera: Curculionidae) fue evaluada durante un periodo de estudio de tres años en el Noroeste Argentino (NOA). Se registró la fluctuación de adultos, huevos y larvas activas en el hospedero soja, además de las formas hibernantes en suelo, larva, pupa y adulto. El ciclo de vida de S. subsignatus es anual y comprende una fase activa, asociada al cultivo de la soja [Glycine max (L) Merr], y otra fase de latencia, durante la cual la plaga permanece en el suelo, sin entrar en contacto con el cultivo. Los primeros adultos se observan en campo desde finales de noviembre y hasta los primeros días de marzo. A partir de allí, los diferentes estadios de desarrollo asociados al hospedero ocurren en tiempos bien definidos. Los huevos en planta aparecen en la segunda mitad de enero y continúan apareciendo durante todo el mes de marzo. El periodo larval se extiende desde los últimos días de enero hasta los últimos días de abril, cuando las larvas saltan al suelo y se entierran para pasar el invierno. Se observan las primeras pupas en los últimos días de septiembre y los adultos, a partir de los últimos días de octubre. Un nuevo ciclo comienza con la emergencia de los adultos, a fines de noviembre o principios de diciembre. Así, se observa que S. subsignatus en la región NOA presenta una generación anual.
