“…The results observed in this research agree with those reported by Arnason et al (1993) when they studied one group of QPM genotypes in relation to maize weevil resistance. The ultimate conclusion possible to draw from this research is the discovery of a group of QPM corn hybrids and lines that carry genes for resistance to the maize weevil, S. zeamais.…”

“…Undesirable characteristics such as reduced yield than normal maize, low grain consistence, and a farinaceous endosperm that retains water resulting in a soft, chalky endosperm that upon drying makes it more prone to insect damage and also affects harvest ability (Singh and Venkatesh 2006). The maize weevil, S. zeamais, is an important pest of maize in the tropical countries of the world (Arnason et al 1993), while maize weevil, S. oryzae, is major pest of maize under field and storage conditions in India. Several weeviltolerant QPM lines have been identified, which can be used in breeding for resistance to this pest (Hossain et al 2007).…”

“…Host plant resistance is one of the effective means of minimizing losses due to insect-pests. However, most of the maize varieties and hybrids released for cultivation are susceptible to C. partellus during vegetative stage (Kumar 1997) and maize weevils, Sitophilus spp., under field and storage conditions (Arnason et al 1993;Hossain et al 2007). Screening of maize germplasm for resistance to spotted stem borer, C. partellus, has led to identification of several maize lines with tolerance to this pest (Kanta et al 1997), and several morphological, anatomical, and biochemical factors have been reported to be associated with resistance/susceptibility to stem borer in maize (Kumar 1997;Bhanot et al 2004).…”

Maize: Nutrition Dynamics and Novel Uses

Maize (Zea mays L.) is an important staple food for millions of people across the world. However, different stress factors mainly the insectpests, viz., maize stalk borer, pink stem borer, sugarcane leafhopper, shoot bug, armyworm, shoot fly, corn leaf aphid, cob borer, and termites, have constrained the increase in yield potential of the maize genotypes deployed in India. The hybrid initiative turned out to be exceedingly important for Quality Protein Maize (QPM) efforts, and many countries in the developing world including India are becoming increasingly interested in QPM to reduce malnourishment and to sustain nutritional security. However, it is also likely that the increase in concentration and quality of nutritional components particularly the protein in QPM might favor the proliferation of insect-pests as they too prefer quality food for their growth and development and could be major constraints to increasing production and productivity of QPM. Therefore, development and deployment of high-yielding and insect-resistant QPM genotypes under the umbrella of integrated pest management system might help in narrowing down the yield gap by reducing the crop losses caused by insect-pests. Since maize is damaged by an array of insect groups with different feeding habits right from the seedling stage to maturity of the crop, no single strategy is sufficient to manage such complex group of insect-pests. Damage potential of different insect-pests, status of host plant resistance and the mechanisms of resistance involved, and the management of major insect-pests have also been discussed in this chapter. IntroductionMaize (Zea mays L.) is the third most important food crop after rice and wheat and is an important staple food for millions of people in Asia, Africa, and Latin America. According to recent estimates, the maize is being cultivated over an

Avaliação da resistência de híbridos de milho ao ataque de Sitophilus zeamais motschulsky ... AbstractResistance of corn hybrids, cultivated or in phase of genetic improvement in Paraná, was evaluated against the attack of Sitophilus zeamais, main grain pest of corn storage. Samples of kernels of eleven hybrids of corn, IPD T1/3AC, IPD 029, IPT 4/029, AG 5011, IPS G/58, IPT 2/15, IPT 4/15, IPT T/23, IPT 5/ T02, IPT 2/92 and IPT 9/13, were infested with adults of S. zeamais and maintained in BOD, at 27±1°C, 75±5% RH and 12 hours of photophase. After 30 days of infestation the following parameters of resistance were evaluated: susceptibility index, reduce of dry mass of the grains, number of emerged insects, biological cycle and adult mass. The most susceptible hybrids to the attack of S. zeamais were: IPD T1/ 3AC and IPD 029; while the most resistant were: IPT 4/029, AG 5011, IPS G/58, IPT 2/15 and IPT 4/15.
