With the recent resurgence in interest in models describing maize (Zea mays L.) development rate responses to temperature, this study uses published data to refit the Poikilotherm equation and compare it to broken stick “heat stress” equations. These data were for the development rate of eight op...

Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is a highly invasive and a polyphagous pest of worldwide importance. Its recent outbreak and rapid spread in Indian cotton growing belt caused large scale devastation. A study was undertaken with a basic assumption that the future distrib...

This chapter describes the application of ILCYM (Insect Life Cycle Modelling) software, which supports the development of process-oriented temperature-driven and age-stage structured insect phenology/population models. ILCYM interactively leads the user through the steps for developing insect phe...

La polilla de la papa Phthorimaea operculella (Zeller) (Lepdidoptera: Gelechiidae) ha co-evolucionado en el centro de origen de la papa en los Andes de Perú y Bolivia. Se ha convertido en una especie invasiva y está reportada en más de 90 países. Se encuentra en casi todos los sistemas de producc...

Retos para la produccion sostenible de papas en un clima cambiante: Una perspectiva de investigacion.
Background: Predicting anopheles vectors’ population densities and boundary shifts is crucial in preparing formalaria risks and unanticipated outbreaks. Although shifts in the distribution and boundaries of the major malariavectors (Anopheles gambiae s.s. and An. arabiensis) across Africa have be...

This paper presents the study of the dynamics of intrahost (insect pests)-pathogen [entomopathogenic fungi (EPF)] interactions. The interaction between the resources from the insect pest and the mycelia of EPF is represented by the Holling and Powell type II functional responses. Because the EPF’...

Potato production systems face constant changes in climate conditions and the projections for the future indicate that changes in temperature and precipitation are expected in certain regions of the world. The impact will depend on what we do today to avoid negative consequences. Climate projecti...

Challenges to sustainable potato production in a changing climate: A research perspective.
Originating from the Andean region and co-evolved with its food plant, the potato (Solanum sp.), the potato tuber moth Phthorimaea operculella (Zeller) has become an invasive potato pest globally. The hypothesis of our present study was that the future distribution and abundance (damage potential...
