Interaction of Cultural, Biological, and Varietal Controls for Management of Stalk Borers in Louisiana Sugarcane
insects Review Interaction of Cultural, Biological, and Varietal Controls for Management of Stalk Borers in Louisiana Sugarcane Thomas E. Reagan * and Megan M. Mulcahy * Department of Entomology, Louisiana State University AgCenter, Baton Rouge, LA 70803, USA * Correspondence: [email protected] (T.E.R.); [email protected] (M.M.M.) Received: 31 July 2019; Accepted: 11 September 2019; Published: 19 September 2019 Abstract: Diatraea saccharalis F is considered the most important pest of sugarcane in the United States. This article focuses on the history of pest management as it relates to the control of this stem borer in Louisiana sugarcane, and how control practices have become more in tune with integrated pest management paradigms. Various pest management strategies are employed against D. saccharalis and the interactions between each of these provide farmers with the tools needed to curb damaging infestations. However, the invasion of the Mexican rice borer, Eoreuma loftini (Dyar), and other confounding environmental factors have presented farmers, consultants, and researchers with new pest management challenges. We address these challenges and provide an overview of ongoing developments, particularly in the Louisiana sugarcane pest management program. Keywords: sugarcane; Diatraea saccharalis; integrated pest management; Eoreuma loftini; Louisiana; stalk borer 1. Introduction The sugarcane borer, Diatraea saccharalis F (Lepidoptera: Crambidae), is native to the West Indies, as well as Central and South America. It was introduced into Louisiana in the 1850s due to the continued importation of sugarcane for production in the state [1]. Since its introduction, D. saccharalis has long been regarded as the most damaging insect pest on the crop. -

Concluding Remarks Acknowledgments Glossary Bibliography Biographical Sketch Summary In this chapter we describe the current state of tropical insect chemical ecology in Latin America with the aim of stimulating the use of this important tool for future generations of technicians and professionals workers in insect pest management. Sex pheromones of tropical insectsUNESCO that have been identified to– date EOLSS are mainly used for detection and population monitoring. Another strategy termed mating disruption, has been used in the control of the tomato pinworm, Keiferia lycopersicella, and the Guatemalan potato moth, Tecia solanivora. Research into other semiochemicals such as kairomones in tropical insects SAMPLErevealed evidence of their presence CHAPTERS in coleopterans. However, additional studies are necessary in order to confirm these laboratory results. In fruit flies, the isolation of potential attractants (kairomone) from Spondias mombin for Anastrepha obliqua was reported recently. The use of semiochemicals to control insect pests is advantageous in that it is safe for humans and the environment. The extensive use of these kinds of technologies could be very important in reducing the use of pesticides with the consequent reduction in the level of contamination caused by these products around the world. -

Resistance of Sugarcane Cultivars to Diatraea Saccharalis
Resistance of sugarcane cultivars to Diatraea saccharalis Leila Luci Dinardo‑Miranda(1), Ivan Antônio dos Anjos(1), Viviane Pereira da Costa(1) and Juliano Vilela Fracasso(1) (1)Instituto Agronômico, Centro de Cana‑de‑açúcar, Rodovia SP 333, Km 321, CEP 14001‑970 Ribeirão Preto, SP, Brazil. E‑mail: [email protected], [email protected], [email protected], [email protected] Abstract – The objective of this work was to evaluate the oviposition preference of Diatraea saccharalis and the effect of ten sugarcane cultivars on larval development. Oviposition preference was assessed under greenhouse conditions by three releases of couples of moths, with subsequent counting of egg masses and eggs per plant. In order to evaluate the effect of the cultivars on larval development, each plant was infected with about 150 eggs, and, 29 days later, the total number of internodes, number of bored internodes, number of life forms found, larval and pupal weight and length, and the width of larval head capsule were evaluated. The cultivars IACSP94-2101 and IACSP96-2042, the least preferred by D. saccharalis for oviposition, and IACSP94-2094, the most unfavorable for larvae entrance and development, show resistance to the pest. Index terms: Saccharum, antibiosis, antixenosis, sugarcane borer.

C. Lee 1, Stacey J. Anderson2, Lucy T. T. Tran-Nguyen3, Nader Sallam4, Bruno P. Le Ru5,6, Desmond Conlong7,8, Kevin Powell 9, Andrew Ward10 & Andrew Mitchell1 Lepidopteran stemborers are among the most damaging agricultural pests worldwide, able to reduce crop yields by up to 40%. Sugarcane is the world’s most prolifc crop, and several stemborer species from the families Noctuidae, Tortricidae, Crambidae and Pyralidae attack sugarcane. Australia is currently free of the most damaging stemborers, but biosecurity eforts are hampered by the difculty in morphologically distinguishing stemborer species. Here we assess the utility of DNA barcoding in identifying stemborer pest species. We review the current state of the COI barcode sequence library for sugarcane stemborers, assembling a dataset of 1297 sequences from 64 species. Sequences were from specimens collected and identifed in this study, downloaded from BOLD or requested from other authors. We performed species delimitation analyses to assess species diversity and the efectiveness of barcoding in this group. Seven species exhibited <0.03 K2P interspecifc diversity, indicating that diagnostic barcoding will work well in most of the studied taxa. We identifed 24 instances of identifcation errors in the online database, which has hampered unambiguous stemborer identifcation using barcodes. Instances of very high within-species diversity indicate that nuclear markers (e.g. 18S, 28S) and additional morphological data (genitalia dissection of all lineages) are needed to confrm species boundaries. -

Christchurch 8140, New Zealand [email protected] ; ORCID: http://orcid.org/0000-0003-3963-1363 ABSTRACT A native isolate of the Beauveria sp. fungus obtained from the Diatraea sp. larva was studied and identified as B. bassiana by analyses based on ribosomal internal transcribed spacer (ITS) sequences. The code given to the isolate was Bv062 and its insecticidal activity was evaluated on the second instar larvae of D. sacchara- lis, D. indigenella, D. tabernella and D. busckella, under laboratory conditions, producing mortality rates of 73.3, 83.3, 67.6 and 24.1 %, respectively. Subsequently, the activity of the fungus was evaluated on D. sac- charalis eggs. Egg mortality was of 82.2 % when spraying a conidial suspension adjusted to a concentration 8 5 of 1 × 10 conidia/mL on the eggs. The mean lethal concentration (LC50) was found to be 9.04 × 10 conidia/ 7 mL and the lethal concentration ninety (LC90) was of 2.07 × 10 conidia/mL on the second instar larvae of D. saccharalis. In-plant bioassays under semi-controlled conditions showed that fungus efficacy was above 50 % with the sporulation of dead larvae of 80 %, using concentrations between 1.0 × 107 and 5.0 × 107 conidia/ mL. -

Crambidae Biosecurity Occurrence Background Subfamilies Short Description Diagnosis
Diaphania nitidalis Chilo infuscatellus Crambidae Webworms, Grass Moths, Shoot Borers Biosecurity BIOSECURITY ALERT This Family is of Biosecurity Concern Occurrence This family occurs in Australia. Background The Crambidae is a large, diverse and ubiquitous family of moths that currently comprises 11,500 species globally, with at least half that number again undescribed. The Crambidae and the Pyralidae constitute the superfamily Pyraloidea. Crambid larvae are concealed feeders with a great diversity in feeding habits, shelter building and hosts, such as: leaf rollers, shoot borers, grass borers, leaf webbers, moss feeders, root feeders that shelter in soil tunnels, and solely aquatic life habits. Many species are economically important pests in crops and stored food products. Subfamilies Until recently, the Crambidae was treated as a subfamily under the Pyralidae (snout moths or grass moths). Now they form the superfamily Pyraloidea with the Pyralidae. The Crambidae currently consists of the following 14 subfamilies: Acentropinae Crambinae Cybalomiinae Glaphyriinae Heliothelinae Lathrotelinae Linostinae Midilinae Musotiminae Odontiinae Pyraustinae Schoenobiinae Scopariinae Spilomelinae Short Description Crambid caterpillars are generally cylindrical, with a semiprognathous head and only primary setae (Fig 1). They are often plainly coloured (Fig. 16, Fig. 19), but can be patterned with longitudinal stripes and pinacula that may give them a spotted appearance (Fig. 10, Fig. 11, Fig. 14, Fig. 22). Prolegs may be reduced in borers (Fig. 16). More detailed descriptions are provided below. This factsheet presents, firstly, diagnostic features for the Pyraloidea (Pyralidae and Crambidae) and then the Crambidae. Information and diagnostic features are then provided for crambids listed as priority biosecurity threats for northern Australia.
