“…Both are capable of causing economic losses to commercial varieties and affect the sugar industry by both direct and indirect crop damages (Leslie 2004, Askarianzadeh et al 2008, Showler & Reagan 2012. Management of stalkboring lepidopterans in sugarcane is multi-tactic, and several control options are used around the world, including biological control (Kuniata & Sweet 1994, cultural practices (Reay-Jones et al 2005, Beuzelin et al 2011, Sandhu et al 2011, varietal resistance (Keeping 2006), and insecticide treatment (Legaspi et al 1999). One relatively new approach to manage stalk borers is the application of silicon as a nutritional amendment.…”

Sugarcane is grown extensively throughout the world including more than 100,000 ha in Khuzestan province, Iran. The pink stalk borers Sesamia are key pests of sugarcane in this region, while other stalk borers will occur in sugarcane worldwide. Application of silicon as a soil amendment has provided plant mitigation to both biotic and abiotic stresses. Silicon has been shown to enhance resistance of sugarcane against stalk borers. Field trials were conducted to determine the effects of calcium silicate against infestations of stalk borers Sesamia spp. and on yield quality. Experiments were conducted with three sugarcane varieties CP69-1062, IRC99-01, and SP70-1143 and two rates of calcium silicate (400 and 800 kg/ha). Percentage of stalk damaged, percentage of bored internodes, length of borer tunnel (mm), number of larvae + pupae per 100 stalks, number of exit holes, and cane yield quality were determined. We demonstrate significant reduction on borer population and damage under silicon treatment, but greater reduction in the percentages of stalk damage, bored internodes, moth exit holes, and length of borer tunnel and number of larvae and pupae per 100 stalks were observed in the susceptible variety CP69-1062. Silicon treatment positively affected cane and sugarcane juice quality of for the variety CP69-1062, but not for SP70-1143. We conclude that the benefits of silicon to sugarcane quality and sugarcane resistance to stalk borers are dependent on the sugarcane variety.

“…8.2 from Beuzelin (2011). Based on data from Beuzelin (2011) and White (1993), the proportions of immature insects in sugarcane and rice remaining after harvest were 0.01 and 0.46, respectively. Only the grains of rice, sorghum, and corn are harvested, but the stalks of sugarcane are harvested.…”

“…Information about Þeld crops in Louisiana (National Agricultural Statistics Service 2010) was used to set planting and harvesting dates (Julian day) for corn (88 and 234), sorghum (92 and 240), and rice (100 and 237) for this model. Sugarcane vegetative seed pieces are planted from August to October with the traditional peak in September, and sugarcane harvest in Louisiana begins in September (Beuzelin 2011). For simplicity, we assumed that sugarcane was harvested on day 272 and planted on day 273.…”

Modeling Evolution of Resistance of Sugarcane Borer (Lepidoptera: Crambidae) to Transgenic Bt Corn

2014

Diatraea saccharalis (F.) (Lepidoptera: Crambidae) is a target pest of transgenic corn expressing Bacillus thuringiensis (Bt) protein, and the first evidence of resistance by D. saccharalis to Cry1Ab corn was detected in a field population in northeast Louisiana in 2004. We used a model of population dynamics and genetics of D. saccharalis to 1) study the effect of interfield dispersal, the first date that larvae enter diapause for overwintering, toxin mortality, the proportion of non-Bt corn in the corn patch, and the area of a crop patch on Bt resistance evolution; and 2) to identify gaps in empirical knowledge for managing D. saccharalis resistance to Bt corn. Increasing, the proportion of corn refuge did not always improve the durability of Bt corn if the landscape also contained sugarcane, sorghum, or rice. In the landscape, which consisted of 90% corn area, 5% sorghum area, and 5% rice area, the durability of single-protein Bt corn was 40 yr when the proportion of corn refuge was 0.2 but 16 yr when the proportion of corn refuge was 0.5. The Bt resistance evolution was sensitive to a change (from Julian date 260 to 272) in the first date larvae enter diapause for overwintering and moth movement. In the landscapes with Bt corn, non-Bt corn, sugarcane, sorghum, and rice, the evolution of Bt resistance accelerated when larvae entered diapause for overwintering early. Intermediate rates of moth movement delayed evolution of resistance more than either extremely low or high rates. This study suggested that heterogeneity in the agrolandscapes may complicate the strategy for managing Bt resistance in D. saccharalis, and designing a Bt resistance management strategy for D. saccharalis is challenging because of a lack of empirical data about overwintering and moth movement.

“…It is one of the main pests of sugarcane (Gallo et al, 2002;Beuzelin et al, 2011) as it can cause a considerable reduction in sugar yields (White et al, 2008). The tunnels excavated by this borer in the stalks cause bud death and germination failure (Bortoli et al, 2003;Portela et al, 2010) and facilitate the invasion of plant pathogens, such as Fusarium moniliforme (Sheldon) and Colletotrichum falcatum (Went), which reduce the yield of sugar Branco et al, 2010).…”

Abstract. The sugarcane borer Diatraea saccharalis is an important pest of sugarcane and ants are one of its main predators. The practice of burning sugarcane straw in situ after harvest has been gradually replaced in Brazil by other practices. However, it is unknown whether ants can control the abundance of this borer in the presence of straw. In this study, we assessed the diversity and species composition of ants attacking different stages of the pest's life cycle. Specifically, we asked whether the species richness and abundance of ants varies during the course of day and a year. We established one-hectare plots at random locations in a sugarcane plantation. Once a month, we collected 20 samples of each stage of the D. saccharalis life cycle and randomly distributed these samples as bait on plants spaced 20 m apart within a plot. Ants were collected daily in the morning and afternoon over a period of 12 months. We identified several aspects of ant feeding behaviour that may affect their biological control of the borer: (1) the greatest number of ants were collected from baits consisting of the immature stages of the sugarcane borer, (2) ants were most active in the morning and (3) their activity varied from month to month. Solenopsis saevissima and morphotypes of Crematogaster sp.7 and Pheidole sp.35 are potentially important predators of borers in sugarcane crops in which the straw is not burnt.
