“…Enhanced cell wall lignification can fortify physical barriers and increase indigestibility to attacking pests. Indeed, class III peroxidases have been linked to host resistance to a wide range of insects (Dowd and Lagrimini, 2006;Garcia-Lara et al, 2007) and pathogens (Choi et al, 2007;Johrde and Schweizer, 2008). It is possible that different mechanisms are deployed against different pests through activation of different class III peroxidases.…”

Reactive oxygen species (ROS) play a major role in plant defense against pathogens, but evidence for their role in defense against insects is still preliminary and inconsistent. In this study, we examined the potential role of ROS in defense of wheat (Triticum aestivum) and rice (Oryza sativa) against Hessian fly (Mayetiola destructor) larvae. Rapid and prolonged accumulation of hydrogen peroxide (H 2 O 2 ) was detected in wheat plants at the attack site during incompatible interactions. Increased accumulation of both H 2 O 2 and superoxide was detected in rice plants during nonhost interactions with the larvae. No increase in accumulation of either H 2 O 2 or superoxide was observed in wheat plants during compatible interactions. A global analysis revealed changes in the abundances of 250 wheat transcripts and 320 rice transcripts encoding proteins potentially involved in ROS homeostasis. A large number of transcripts encoded class III peroxidases that increased in abundance during both incompatible and nonhost interactions, whereas the levels of these transcripts decreased in susceptible wheat during compatible interactions. The higher levels of class III peroxidase transcripts were associated with elevated enzymatic activity of peroxidases at the attack site in plants during incompatible and nonhost interactions. Overall, our data indicate that class III peroxidases may play a role in ROS generation in resistant wheat and nonhost rice plants during response to Hessian fly attacks.

“…Resistance to maize weevils is related to certain physical factors such as kernel hardness (Dobie 1977) nutritional factors such as carbohydrates, lipids and proteins, or non-nutritional factors, such as phenolic compounds (Arnarson et al 1992). García-Lara et al (2007) also reported that some of the mechanisms for weevil resistance are associated with protein, fibre, and various pericarp cell phenolic acid compounds, structural proteins and enzymes such as peroxidase.…”

“…Information on gene action well help determine maize weevil resistance in designing strategies to develop resistant maize varieties (Derera et al 2000;Dhliwayo et al 2005). A greater understanding of the biochemical and structural mechanisms of weevil resistance in maize grain suggests opportunities for molecularassisted breeding strategies (García-Lara et al 2007).…”

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.)

“…Maize hybrids that exhibit low grain weight loss for example, CZH131022 are often characterized with high levels of phenolic compounds. Different phenolic compounds such as coumaric acid esterified to carbohydrates on the maize pericarp tend to discourage successful utilization of a maize variety as an ideal host by an insect thereby resulting in low percentages of grain weight loss (García-Lara et al, 2007). As suggested by the results (Table 3), there is high variation in kernel volume amongst all drought tolerant maize hybrids evaluated for weevil resistance in this particular study.…”

This study was carried out to evaluate and assess the phenotypic correlation between the primary and secondary weevil resistant traits of 20 drought tolerant (DT) late maturing maize hybrids (LHYB) to weevil (Sitophilus zeamais Motschulsky) damage. Well-conditioned experimental samples with uniform grain moisture content were infested with 32; 10 to 14 day old weevils in the controlled temperature and humidity (CTH) environment for 55 days. Data were collected on kernel volume (KV) and grain hardness (GH) at the start of the experiment, percent weevil mortality (%WM) at the 21 st day and percent grain weight loss (%GWL) and F 1 weevil progeny emergence (F 1 WPE) at the 55 th day of oviposition. Data were collected on starch, oil and protein content to confer resistance to weevil damage. There were highly significant differences (P<0.001) in F 1 WPE and %GWL, (P<0, 01) in KV while no significant differences were observed for %WM and GH. The obtained data confirmed that, there was a positive and significant correlation between F 1 WPE and %GWL, while a negative and significant correlation was observed between F 1 WPE and %WM.
