The timing of pest insect attacks can vary greatly from region to region and from year to year. A simulation method, based on rates of insect development, has been developed for forecasting the timing of insect attacks on cruciferous crops. The method is based on using a fixed number of individuals from one generation to the next and simulates the timing of events in the life cycle of the pests...

the aim of this study was investigation the combined effect of terminal heat of last growth season and competition between plants on phenology, yield and components yield in faba bean. a field experiment with 3 sowing dates (28 november 2011, 15 december 2011 and 7 january 2012) and 4 plant densities (8, 12, 16 and 20 plants m-2) was conducted on faba bean (cv. barkat) at agricultural science r...

Weed control is one of the most important crop protection activities undertaken in both intensive and low-input farming systems. However, even under intensive systems, crop protection which is less dependent on pesticides may require that weeds be managed to obtain a balance between crop and non-crop vegetation to encourage an increase in natural enemies of crop pests. In the low-input farming ...

given the importance of sustainable agricultural development, using non-chemical weed management such as cover crops and decreasing row spacing has an importance in weed control and reducing herbicide use. in order to an experiment was conducted at agricultural research site in agricultural college, university of mohaghegh ardabili in 2011. the experiment done as factorial based on randomized c...

Introduction Resistance is a natural phenomenon, a result of evolution and adaptation to environment. When a pest population is exposed to a pest management tool, whether chemical, biological, or cultural, the individuals in that population that are genetically predisposed to overcome the management tool are more likely to survive and pass their genes on to the next generation. Over multiple ge...

A capture-mark-recapture study was conducted in crop fields in Morogoro, Tanzania, to investigate how the population dynamics of multimammate field rats, Mastomys natalensis, was influenced by the commonly practised land preparation methods and cropping systems. Two land preparation methods (tractor ploughing and slash and burn) and two cropping systems (mono-cropping with maize and inter-cropp...

The alien invasive insect pest, Spodoptera frugiperda Smith (Lepidoptera: Noctuidae), commonly referred as to fall armyworm (FAW), is causing significant losses maize production in Africa since its detection 2016. Despite being the primary pest of main food crop country, researchers are more focused on control methods’ development. There no or little research done seasonality which greatly help...
