“…Sugarcane is a strategically important crop that has economic and social impact in many countries, but it is vulnerable to many biotic stressors and among them, lepidopteran stalk borers are the most destructive in many sugar-producing countries, including Brazil (Volpe et al 2014), South Africa (Keeping 2006), Indonesia , Reunion Island (Nibouche & Tibère 2008), the USA (Showler & Reagan 2012), Mexico (Vejar-Cota et al 2008), Iran (Jamshidnia et al 2010), Colombia (Vargas et al 2013), India (Srivastava et al 2012), and Papua New Guinea (Kuniata & Sweet 1994).…”

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.

Although the stem borer Sesamia nonagrioides (Lefèbvre, 1827) is one of the most destructive agricultural pests in South and Southwest Iran, the structure of these populations is not yet well understood. In this study, we sequenced two mitochondrial genes (CO1 and Cyt-b) of populations collected in cultivated sugarcane and rice in South and Southwest Iran. These genetic data of Iranian populations were compared with those of already published data from West Palaearctic (Africa and Europe). To testing the intra-and inter-population variations, different population analyses (e.g. haplotype network, haplotype and nucleotide diversity) were executed. Our results indicate a considerable genetic variation in Iranian populations of S. nonagrioides, which supports the long-term establishment of S. nonagrioides populations in Iran versus a recent invasion. Close genetic relationship of Iranian population of S. nonagrioides with a population of Central Ethiopia supports the scenario of the origin of this species from Africa to western Asia through the Trans-Arabian bridge. Our results help to explain the variation in pest status of S. nonagrioides observed across its distribution range in Iran.Key words: CO1, Cyt-b, gene flow, haplotype, population genetics. INTRODUCTIONThe stem borer Sesamia nonagrioides (Lefèbvre, 1827) (Lepidoptera: Noctuidae) is one of the most damaging sugarcane pests in sugarcane agro-industries of Khuzestan province (Southwest Iran) since 1950's. It is also a pest of maize and rice in provinces of Khuzestan and Fars (South Iran) where it completes four to five generations annually (Khanjani 2004, Cherghali et al. 2015. The pest status of S. nonagrioides on different crops varies across its distribution range in Iran (Cherghali et al. 2015). Pest management strategies of this economic pest in sugarcane fields of south-western Iran include releasing the egg parasitoid wasp Telenomus busseolae Gahan (Hym., Scelionidae) (Jamshidnia et al. 2010).

Pesticides are used by farmers in the case of heavy damage to maize and rice. Management practices of S. nonagrioides in Iran ignore the possible existence of genetic diversity among populations of this pest and its range of distribution.The species S. nonagrioides, is considered one of the most important pests of maize in many countries around the Mediterranean region where it is known as the Mediterranean corn borer or corn stalk borer (De La Poza et al. 2008). This pest has been traditionally regarded as a rather sedentary pest , Eizaguirre et al. 2004, Margaritopoulos et al. 2007), likely to develop genetic isolation between geographical regions. Genetic differentiation between S. nonagrioides populations in European countries has been reported usi...

“…Although one of the most important methods to assess the efficiency of a natural enemy in regulating the pest populations is to evaluate their behavioral characteristics, including functional response [41,42], this index could be significantly influenced by biological and environmental factors, which makes it difficult to predict the potential of biological control agents. We considered predation rate to be a better index for future assessments because it is a more explicit index for researchers to evaluate the effect of fungal predators on the targeted pests and has been widely used in the assessments of Hr or other fungal biological control agents [43,44].…”

Functional response is a key index in determining the population fluctuation in predation. However, the lack of operable research system limits the studies on functional response of fungal predators. Hirsutella rhossiliensis is a dominant parasite of the soybean cyst nematode, Heterodera glycines. In a soil microcosm bioassay, we determined fungal biomass at different days within 21 days after inoculation, and parasitism rate of H. glycines by the fungus was determined. The functional response of H. rhossiliensis to H. glycines was established and found to be Holling's type III, which was influenced by mycelial densities. Meanwhile, we conducted anti-fungal analysis of metabolic fractions extracted from H. rhossiliensis to explain the potential mechanism of the intraspecific competition illustrated by functional response. The result of anti-fungal experiments indicated that the fungal predators had more complicated interaction at population level than expected, which might be regulated by self-inhibition metabolite(s). This study was the first functional response study of fungal predators in microcosm. With the increasing recognition of emerging fungal threats to animal, plant, and ecosystem health, the methodologies and hypotheses proposed in this study might inspire further research in fungal ecology. fungal predator, predation index, self-inhibition composition, soybean cyst nematode Citation:
