“…larvae fed with Sifertilized maize plants [61,37,62,24] and for Chilo infuscatellus Snellen, 1890 (Lepidoptera: Crambidae) fed with Si-fertilized sugarcane plants [63]. Despite the reduction of damage by Si fertilization have already been reported for other herbivores in sugarcane [64,17,57], including D. saccharalis [23], this study is the second in the literature to demonstrate the effect of silicon on the larval performance of D. saccharalis. Previously, [65], reported that there was no effect of silicon on the larval weight of D. saccharalis, differing from our results.…”

“…The accumulation of Si in plants confers resistance to herbivore attack through physical and mechanical barriers [57,54,55]. The deposition of silica in the epidermal cells of the thatch increases its hardness and abrasiveness, providing a mechanical barrier to the penetration of D. saccharalis larvae into the thatch of early-stage plants [58,59].…”

Sugarcane borer, Diatraea saccharalis, is one of the main insect pests of sugarcane elds, and it has been mainly managed by the use of chemical or biological controls. Considering the bene ts of Silicon (Si) fertilization against pests, it was assessed the development of sugarcane borer larvae and sugarcane growth with and without Si. A greenhouse experiment was conducted using a factorial design (2x2) with 10 repetitions. Two commercial sugarcane varieties were evaluated: SP80-3280 and IAC91-1099, which has, respectively, susceptibility, and intermediate resistance to D. saccharalis. Si was applied in soil in an equivalent rate of 800 kg of Si ha − 1 . Before herbivory, Si increased stalk diameter and plant height in both varieties, and number of leaves and leaf width were only increased in IAC91-1099. After 20 days of herbivory, Si increased stalk diameter in both varieties and plant height in IAC91-1099, but decreased the number of leaves and leaf width in SP80-3280. Larval D. saccharalis showed a reduced weight and a greater index for mandible abrasion after feeding Si-treated plants independently of variety. No in uence of Si-treated plants was found in immunological parameters of larvae (total number of hemocytes, cell viability, encapsulation capability, lysozyme active). The activity of phenol oxidase, an immunological and stress marker for insects, was greater in larval D. saccharalis fed with IAC 91-1099, independently of Si. In conclusion, Si application improved sugarcane growth of IAC91-1099 and impaired the development of larval D. saccharalis in both sugarcane varieties.

“…Even though recent sugarcane stem borer pest outbreaks in Colombia are possibly associated with D. busckella and D. tabernella population increases and due to the fact that genotypes with greater resistance have been replaced by less resistant genotypes (Echeverri-Rubiano et al 2018), thus far it is not clear whether sugarcane varieties exhibit differential host-plant resistance responses to different Diatraea species. In addition, most studies focus only on D. saccharalis, while only a few have focused on D. indigenella (Pastrana et al 1993) and D. tabernella (Atencio et al 2017(Atencio et al , 2018.…”

Evaluation of host-plant resistance on sugarcane to the sugarcane stem borers of Diatraea spp. is normally conducted in Colombia under field conditions, where environmental variations make the study of the insect–plant relationships difficult. Additionally, several species (i.e., D. saccharalis, D. indigenella, D. tabernella, and D. busckella), which are predominant in Colombia, can overlap in their distribution, raising the question of whether different varieties have the same responses to different pest species. The present study conducted evaluations of host-plant resistance under screen house conditions using two contrasting varieties (CC 93-3895, resistant, and CC 93-3826, susceptible) that were infested with the above-mentioned borer species. Observations of pest injury were conducted on internodes, leaves, and spindles. Survival and size (body mass) of the individuals recovered were analyzed and a Damage Survival Ratio (DSR) was proposed. The resistant CC 93-3895 exhibited less stalk injury, less emergence holes on internodes, and lower DSR; additionally, recovery of pest individuals was lower in comparison with CC 93-3826, independent of the borer species. Insect–plant interactions are discussed, as no previous information was available for three of the species tested (i.e., D. tabernella, D. indigenella, and D. busckella). This screen house protocol is proposed to characterize host-plant resistance among several cultivars from the Colombian sugarcane germplasm bank, using CC 93-3826 and CC 93-3895 as contrasting controls and D. saccharalis as the species model.
