“…Currently, farmers use chemical and cultural methods to control maize weevils in storage; some farmers, however, lack proper storage facilities and cannot afford chemical protection for their maize in storage (Perez-Mendoza 1999). Host plant resistance provides an alternative method for controlling maize weevil in storage (Dobie 1977;García-Lara et al 2009).…”

Maize weevil (Sitophilus zeamais Motschulsky) is one of the major maize storage pests among smallholder farmers in eastern and southern Africa (ESA), thereby, reducing total on-farm maize harvests. Experiments were conducted in a controlled temperature and humidity (CTH) laboratory at CIMMYT-Zimbabwe to compare the resistance of new maize open pollinated varieties (OPVs) from regional trials undertaken in ESA to maize weevils. Twenty maize OPVs were shelled and cleaned before being placed in a deep freezer at -20°C to kill any pests and eggs in the grain from the field. Fifty grams of grain from each OPV was measured after 3 weeks and placed in the CTH lab for conditioning. The samples were placed in 250-mL jars with brass-screened lids and then infested with 32 maize weevils aged between 10 and 14 days. Data were collected for kernel hardness prior to weevil infestation, as kernel hardness to confer resistance to weevils. The components of maize weevil resistance considered were: median development period, Dobie index of susceptibility, weevil emergence, weevil mortality, weevil fecundity, grain weight loss, kernel damage and germination. There were highly significant differences in maize kernel characteristics and median development period (P \ 0.001) among the maize OPVs. There were significant differences in the number of damaged kernels, grain weight loss (P \ 0.01), weevil mortality and germination (P \ 0.05) among the maize OPVs. There were no significant differences found for weevil progeny emergence (F 1 ), Dobie index of susceptibility and weevil fecundity, the last of which was positively and significantly correlated with kernel damage (P \0.001). The DIS was positively and significantly correlated with weight loss and F 1 (P \ 0.001). The maize OPVs 07WEEVIL, Chitedze6, Strigoff126, Strigoff128 and ZM625 were found to be resistant; on the other hand, Strigoff140, Strigoff125, Strigoff133, VP05199 and VP074 varieties were highly susceptible.Keywords Controlled temperature and humidity laboratory Á Kernel hardness Á Open pollinated varieties Á Sitophilus zeamais Á Zea mays (L.)

“…As a primary pest, it can easily infest sound kernels, while it is particularly important in warm climates, where it can cause very serious losses in stored maize, as well as in maize before harvest (Crop Protection Compendium, 2002). Furthermore, it shows resistance to insecticides (Perez-Mendoza, 1999;Fragoso et al, 2003). In studies conducted in our laboratories recently we have made significant progress in clarifying some aspects of the behavior of S. oryzae and T. confusum (Athanassiou et al, 2006).…”

Laboratory kernel-kernel interaction experiments were carried out to assess the influence of mechanically damaged, insect-damaged, and intact maize kernels (conditioned or not) on the behavior of adult maize weevil, Sitophilus zeamais Motschulsky. S. zeamais adults were much more attracted to insect-damaged or conditioned insect-damaged kernels, than by the other two conditioned kernel categories considered. The intact kernels were more attractive than conditioned mechanically damaged kernels, but without significant difference. The "attractiveness" order of the kernel for S. zeamais adults was: insect damagedϾintactϾmechanically damaged. When fresh mechanically damaged and stored mechanically damaged kernels as well as fresh insect-damaged and stored insect-damaged kernels were compared, significant differences in the attraction of S. zeamais adults were noted.

“…Control methods of insects are based on the use of insecticides, which are generally the most effective management tools and provide the only feasible method of reducing insect pest population to acceptable levels [25,26]. However, is important to know the effect of the insecticidal agents on the pests to avoid possible development of resistance and evaluate the implementation of the product in the ecosystem.…”
