“…E. loftini has been collected from numerous grasses (Poaceae), Canna spp. (Cannaceae), and bulrush (Cyperaceae: Scirpus validus Vahl) (Osborn and Phillips 1946, Johnson 1984, Showler et al 2011. D. saccharalis larvae also feed on a range of noncrop grasses comparable to that reported for E. loftini (Jones and Bradley 1924, Holloway et al 1928, Box 1956, Bessin and Reagan 1990.…”

“…Conversely, nearby plants may increase plant host availability and release additional host-Þnding stimuli for insect pests, thus enhancing pest populations (Karban 1997, Tindall et al 2004. Previous studies have suggested that noncrop hosts could play a key role in E. loftini and D. saccharalis population dynamics in Gulf Coast agroecosystems , Showler et al 2011). However, the quantiÞcation of noncrop host presence and use has been limited, especially when crop hosts are absent or too young to sustain stem borer development.…”

Seasonal Infestations of Two Stem Borers (Lepidoptera: Crambidae) in Noncrop Grasses of Gulf Coast Rice Agroecosystems

Infestations of two stem borers, Eoreuma loftini (Dyar) and Diatraea saccharalis (F.) (Lepidoptera: Crambidae), were compared in noncrop grasses adjacent to rice (Oryza sativa L.) fields. Three farms in the Texas rice Gulf Coast production area were surveyed every 6-8 wk between 2007 and 2009 using quadrat sampling along transects. Although D. saccharalis densities were relatively low, E. loftini average densities ranged from 0.3 to 5.7 immatures per m(2) throughout the 2-yr period. Early annual grasses including ryegrass, Lolium spp., and brome, Bromus spp., were infested during the spring, whereas the perennial johnsongrass, Sorghum halepense (L.) Pers., and Vasey's grass, Paspalum urvillei Steud., were infested throughout the year. Johnsongrass was the most prevalent host (41-78% relative abundance), but Vasey's grass (13-40% relative abundance) harbored as much as 62% of the recovered E. loftini immatures (during the winter). Young rice in newly planted fields did not host stem borers before June. April sampling in fallow rice fields showed that any available live grass material, volunteer rice or weed, can serve as a host during the spring. Our study suggests that noncrop grasses are year-round sources of E. loftini in Texas rice agroecosystems and may increase pest populations.

“…Where sugarcane and maize are grown (along with other crops) as a patchwork agricultural landscape, such as the Lower Rio Grande Valley, E. loftini-susceptible maize, preferred over sugarcane [51,52], can accumulate the pest until the maize is harvested and the adults move into sugarcane [52]. Three months after August harvest of maize in the Lower Rio Grande Valley, larval entry holes in November-harvested sugarcane stalks (sugarcane in south Texas is usually harvested November-December) had increased by 7-to 8-fold ( Figure 5) [52].…”

Selected Abiotic and Biotic Environmental Stress Factors Affecting Two Economically Important Sugarcane Stalk Boring Pests in the United States

Sugarcane, Saccharum spp., in the United States is attacked by a number of different arthropod pests. The most serious among those pests are two stalk boring moths in the Family Crambidae: the sugarcane borer, Diatraea saccharalis (F.), and the Mexican rice borer, Eoreuma loftini (Dyar). The two species are affected by abiotic and biotic environmental stress factors. Water deficit and excessive soil nitrogen alter physical and physiochemical aspects of the sugarcane plant that make the crop increasingly vulnerable to E. loftini. Weed growth can be competitive with sugarcane but it also supports enhanced abundances and diversity of natural enemies that can suppress infestations of D. saccharalis. In an instance where the stalk borer is considered a stress factor, proximity of vulnerable crops to sugarcane can influence levels of E. loftini infestation of sugarcane. The adverse effects of each stress factor, in terms of stalk borer attack, can be reduced by adopting appropriate cultural practices, such as adequate irrigation, judicious use of nitrogen fertilizer, using noncompetitive weed growth, and not planting vulnerable crops near sugarcane fields. Understanding the relationships between stress factors and crop pests can provide valuable insights for plant breeders and tools for incorporation into integrated pest management strategies.
