Oviposition of weevil, Sitophilus Zeamais (Coleoptera, Curculionidae) and morphometric characteristics of native maize from southeastern Mexico
Knowing the diversity and uses of corn is essential for food security. The characteristics of the seeds are important because they have particular characteristics that producers look for in their consumption or storage. In ten maize materials (seven natives and three free pollination varieties) information was obtained on the morphometric characteristics in seeds (length, width, thickness, and area), percentage of floury and crystalline endosperm through images, hardness with the help of a Sitophilus texturometer and oviposition through of a staining technique. Differences were identified between all the materials in all the variables analyzed. The Sac beh and Nukuch nah materials registered higher hardness, they also excelled in the amount of crystalline endosperm registering 85 and 84% respectively, however, the Sac beh was one of the most affected with the oviposition of Sitophilus with nine eggs per 10 seeds on average, in contrast to Chac choc (red seed) which was not affected. The variability within the native materials can provide alternatives for genetic improvement programs oriented to postharvest handling and have characteristics that together reduce the effects of the Sitophilus attack.
