“…This is also reported in other studies on Orthoptera (Johnson & Pavlikova, 1986;Johnson & Mündel, 1987;Mariottini et al, 2011). The body weight of the females of the three species used in the present study was greater than that of the males (Table 1).…”

“…Although there are several studies on the feeding habits and food consumption of various orthopteroid species (Bailey & Mukerji, 1976;Hoekstra & Beenakkers, 1976;Jonson & Mündel, 1987;Akman-Gündüz & Gülel, 2002;Bardi et al, 2011;Mariottini et al, 2011;Syed et al, 2011) there are no relevant reports for Greece. On the other hand most of the data on the feeding rate of Orthoptera are records for one temperature although it is well known that insect food intake is temperature dependent (Ferro et al, 1985;Logan et al, 1985).…”

Abstract. In the Mediterranean area the orthopterans Calliptamus barbarus barbarus, Dociostaurus maroccanus and Tettigonia viridissima are considered to be pests of major economic importance crop plants. The aim of the present study was to evaluate the area of leaf of vine, cotton and potato plants consumed by these Orthoptera at two temperatures. Leaf area was determined for each plant species before the leaves were provided to the insects. Virgin male and female adults were allowed to feed on a leaf of each plant species and the area of leaf consumed was determined after 24h at 25 and 30°C. Results showed that temperature had a significant affect on consumption by both males and females of all the species examined, and it was higher at 30°C. The influence of plant species was not significant for C. barbarus barbarus. D. maroccanus and T. viridissima, however, consumed a greater area of potato leaves than of the other species of plants. Females consumed more food than males in all the species tested. The results of the present study provide a first approximation of the area of leaf consumed and the potential loss of foliage these plants might suffer if attacked by the three species of Orthoptera tested.

“…About one quarter of the approximately 200 species of grasshoppers known for Argentina were reported for the Pampas (Carbonell, Cigliano, and Lange 2006). Some of these species, up to six but notably Dichroplus maculipennis (Blanchard) and Dichroplus elongatus Giglio-Tos, constitute recurrent pests that cause serious losses to forage and various crops during outbreaks (Lange, Cigliano, and De Wysiecki 2005;Mariottini, De Wysiecki, and Lange 2011 (Samways 1997). All grasshopper species of Argentina are native (Carbonell et al 2006), and no reports exist on the endangerment status of any of the species.…”

After experimental introductions from North America in 1978Á1982, the biocontrol agent Paranosema locustae became established in grasshopper communities of the western Pampas region of Argentina. The use and establishment of P. locustae in Argentina constitute both a case of neoclassical or new association biological control (use of an alien species against native pests) and a case of pathogen pollution (anthropogenic introductionÁestablishment of an infectious disease in populations of native species). Since P. locustae is a multihost pathogen among grasshoppers, its presence in the western Pampas represents an additional factor disrupting grasshopper communities according to the differential susceptibility of each species and possibly threatening some species. Microscopic examination of 504 grasshopper samples (the mean number of individuals per sample 0 185) belonging to 43 species from 93 localities throughout the Pampas revealed an establishment area of approximate 90,000 km 2 from about 358 North to 388 South and from 618 East to 658 West. Field infections by P. locustae have now been detected in 21 grasshopper species in the western Pampas. Susceptible species with geographic distributions mostly restricted to the establishment area and with numerically small populations, like the melanopline Scotussa daguerrei, are predicted to be the ones facing higher risks of negative impacts.

“…One of these species is Dichroplus maculipennis (Blanchard) which causes damage in grasslands and in economically important crops such as maize, soybean, and wheat, among others (Carbonell et al 2006, Mariottini et al 2013). These grasshoppers mainly consume leaves but they often also eat the stems (Mariottini et al 2011a). Dichroplus maculipennis occurs in much of Argentina and Chile, Uruguay, and southernmost Brazil (Carbonell et al 2006, Mariottini et al 2011b).…”

In this study, the effects of strain Beauveria bassiana (LPSC 1067) as an endophyte in corn plants on consumption, fecundity, and food preference of Dichroplus maculipennis were examined. We observed that the daily consumption by grasshoppers fed with control plants was almost twice that of those that were fed treated plants. Significant differences in fecundity of grasshoppers that were fed with treated plants compared with those that only fed on control plants were also observed. The number of eggs laid per female fed with control plants was 27.2, while the number of eggs laid per female that were fed during 15 d with treated plants was 17.7. Similar results were observed when the number of embryonated eggs was evaluated. The highest number of embryonated eggs were recorded in those females that only fed on control plants (96%) while fewer embryonated eggs were recorded in grasshoppers fed for 15 d with treated plants only (25%). In relation to food preference the average consumption rate for D. maculipennis females on control corn plants was 303.8 ± 24.5 mg while it was only 25 ± 2.1 mg on plants treated with B. bassiana as an endophyte. In summary, we observed that B. bassiana as a corn plant endophyte negatively affected the daily consumption rate, fecundity and food preference of D. maculipennis.
