چکیده

Insect pests are a major cause of crop loss globally. Pest management will be effective and efficient if we can predict the occurrence of peak activities of a given pest. Research efforts are going on to understand the pest dynamics by applying analytical and other techniques on pest surveillance data sets. In this study we make an effort to understand pest population dynamics using Neural Networks by analyzing pest surveillance data set of Helicoverpa armigera or Pod borer on chickpea (Cicer arietinum L.) crop. The results show that neural network method successfully predicts the pest attack incidences for one week in advance.

Biological activity of soybean trypsin inhibitor and plant lectins against cotton bollworm/legume pod borer, Helicoverpa armigera

The noctuid, Helicoverpa armigera, is the most important crop pest worldwide. We evaluated the biological activity of soybean trypsin inhibitor and plant lectins against this pest to identify toxin genes for deployment through transgenic plants. Of the seven plant lectins tested, chickpea and snowdrop lectins showed marked antibiotic effects in terms of insect survival and development. Larval s...

Exploitation of wild relatives of pigeonpea and chickpea for resistance to Helicoverpa armigera

Wild relatives continue to evolve in nature, and live by a different rule than the crop plants – which is survival of the fittest. Wild species have evolved to survive droughts, floods, extremes of heat and cold, and have the capability to withstand damage by insect pests and diseases that cause heavy damage to cultivated species. Many improved cultivars of crops are vulnerable to insect pests ...

Purification of trypsin inhibitor from seeds of Cicer arietinum (L.) and its insecticidal potential against Helicoverpa armigera (Hübner)

INTRODUCTION Cicer arietinum is an important self-pollinated diploid crop 2n=2x=16 with genome sized approximately 931 Mbp (Arumuganathan and Earle 1991). India is the largest producer of chickpea, contributing with about 66% of the total global production, followed by Turkey, Pakistan and Mexico (Thangwana and Ogola 2012). It is a major source of protein (12.4-31.5%), energy, fiber, vitamins, ...
