“…The mean fruit damage showed highly significant differences dependent on the month of sampling (F = 16.37; df = 5; P = .0001). The first indications of damage were observed in February (4), which were similar to what was observed in November (5). A higher incidence occurred in March (21) and October (18) (Figure 2).…”

“…This flexibility, according to the phenology of the crop and response to abiotic factors, increases the risk of damage. For example, for the bean borer Cydia fabivora Stansly and Sanchez [5] report a higher oviposition on the underside of the leaf prior to flowering (55%). However, when the pods emerge, they are preferred for oviposition (84%).…”

We evaluated the damage patterns produced by females of the guava weevilConotrachelus dimidiatusChampion, 1904 (Coleoptera: Curculionidae), according to the position of the damaged fruit in guava treesPsidium guajavaL. in Calvillo, Aguascalientes, Mexico. The trees were subdivided in eight zones, and during one year the level of fruit lesions due to oviposition was registered. Results showed a higher level of damage in the upper and external zone of the trees(P≤.05). We found no significant differences in damage between the four cardinal points(P≥.05). During the year, the level of damage was recorded and was higher in the months of August and September(P≤.05)associated with rainfall (0.86,P=.06) and increase in temperature (0.84,P=.03). The most susceptible fruits were in the size range of 2.1–4.0 cm (polar diameter). The information from this study will be used to design and establish effective control strategies for the guava weevil, taking into account location of the most susceptible fruits, seasonality of the pest, and the abiotic factors.
