Pest phenological models
The study of the biological development of pests in relation to climatic conditions, especially temperature
KNOWING the life cycle of pests
increases the success of its CONTROL
Biological changes of insects (eggs, larvae, pupae, adults) are conditioned to environmental temperature.
The development of pests depends on the ambient temperature. Each species needs a certain temperature to develop.
The combination of temperature (between thresholds) and time is expressed in units called degree-days.
The accumulated degree-days are used to predict when an insect will reach a certain stage of its life cycle, the number of generations, or the most efficient time for treatment.
The study of the biological development of pests in relation to climatic conditions, especially temperature
Insecticides that are applied to an insect pest based on a calendar date or on indications obtained from sampling often fail to achieve the expected control and are a waste of resources.
For treatments to be efficient, it is necessary to take into account the development of the crop, the development of the pest and its population density.
La actividad de los insectos varía de un año a otro en función de la climatología, principalmente la temperatura. La temperatura corporal de los insectos y su crecimiento se ven afectados por la temperatura ambiente.
Cada especie necesita una acumulación de calor para alcanzar ciertas etapas de su vida, como la eclosión de los huevos o el vuelo de los adultos.
Las plagas se desarrollan más rápidamente en climas cálidos que en climas fríos, pero la cantidad de calor necesaria para completar el desarrollo de un organismo no varía.varía.
Insect activity varies from year to year depending on the weather, mainly temperature. Insects body temperature and growth are affected by the ambient temperature. Each species needs an accumulation of heat to reach certain life stages, such as egg hatching or adult flight. Pests develop more rapidly in warm climates than in cold climates, but the amount of heat needed to complete an organism's development does not vary.
Degree day values interpret the heat buildup of pests. When used to determine the timing of treatment, they increase the effectiveness of an Integrated Pest Management program, and provide a cost-effective tool for reducing pest damage.
FuturCrop records daily weather data affecting crops in a given location, analyzes it with phenological models and reports on the stage of development of pests, the optimal time for treatment and predicts when treatment should be carried out.

Phenological modeling and degree-day summation are techniques that have been used by universities in the USA to predict pest activity for several decades.
This functionality has been implemented in on-line tools that take advantage of data from weather stations in each State and estimate the timing of pest activity, at a specific location.
Scientists have studied the biological development of insects in correlation with cumulative degree-days, discovering information about key developmental stages, such as egg hatching, adult flight, etc.
Insect models are useful when scheduling insecticide treatment because the entire life cycle (or some important events) of the insect is known.
The accumulated degree days are useful for scheduling pest sampling, when to place traps, when to look for damage, when to take samples, etc.
FuturCrop also includes description and photographs of the pest, which allows its identification and sampling instructions according to the stage of development of the pest.
Some insect life stages are more susceptible to insecticide treatment, such as young larvae or mealybugs. Degree-days are used to predict these life stages.
Degree-days are "projected" into the future for a given location, in order to calculate the best day for carry out pest control treatments,.
Providing information on pest risks and development increases efficacy and helps reduce the environmental impact of pesticides,
Using a pest management model based on knowledge of the life cycle of pests saves more than 40% and 70% of costs in pesticides and biopesticides, respectively.
