“…In South and Southwestern Brazil, the neotropical stink bug Dichelops melacanthus (Dallas) (Hemiptera: Pentatomidae) is one of the major pests for corn (Zea mays L.) and wheat (Triticum aestivum L.), and a secondary pest for soybean [Glycine max (L.) Merill] (Ávila & Panizzi, 1995;Chocorosqui & Panizzi, 2004;Manfredi-Coimbra et al, 2005). The impact of D. melacanthus in cultivated areas has increased in recent years mainly because the extensive adoption of crop rotation in no-tillage cultivation systems, favors stink bugs by offering a continuous food supply and by enhancing their ability to survive in adverse periods of the year (winter or dry seasons) under crop debris (Chocorosqui & Panizzi, 2004;Carvalho, 2007).…”

“…The damage caused by D. melacanthus is more serious during the growth phase of the crop (vegetative phase), because of the injection of saliva at the time of feeding. This causes transverse punctures, necrosis, winding and/or drying of the aerial part (GOMEZ; ÁVILA, 2004;MANFREDI-COIMBRA et al, 2005). However, the occurrence of N. viridula is greater during the reproductive phase (development of the spikes), which may lead to drying of the spikes and death of the plants ( MANFREDI-COIMBRA et al, 2005).…”

Pathogenicity of Metarhizium anisopliae isolates on Nezara viridula and Dichelops melacanthus in wheat crop

Bugs such as Nezara viridula (Linnaeus) and Dichelops melacanthus (Dallas) are considered the main insect pests of wheat crop in Brazil. The use of the entomopathogenic fungus Metarhizium anisopliae (Metschnikoff) may be an alternative for the management of these insects in the crop. The objective of this work was to verify the pathogenicity of different isolates of M. anisopliae on adults of N. viridula and D. melacanthus under laboratory and greenhouse conditions. In the laboratory, isolates 05RA, 11RA, 08RA and 02RA were obtained from N. viridula and D. melacanthus infested with M. anisopliae. Also, a high pathogenicity (100% of mortality) of both species was recorded in a bioassay of the topical application 8 Days After Application (DAA). However, compared to the other isolates, the 08RA isolate showed the highest pathogenicity in a shorter time interval for N. viridula (Mean Time “MT” = 2.8 days) and D. melacanthus (MT = 4.0 days). Under greenhouse conditions, the 08RA isolate provided a mortality of 44.9% (N. viridula) and 35.7% (D. melacanthus) in the same evaluation period. However, at 14 DAA, the mortality was 100% for both species, with the MT values of N. viridula and D. melacanthus being obtained at 8 days and 10 days, respectively. The fungus M. anisopliae is a promising alternative for the control of adult N. viridula and D. melacanthus in wheat crop.

“…Another important consequence is abnormal tiller formation leading to a symptom known as "cebolinha" (chive) (Gomez and Ávila 2004;Manfredi-Coimbra et al, 2005). On the other hand, the damage by N. viridula is more pronounced during the reproductive phase (ear development) and may lead to ear drying and plant death (Manfredi-Coimba et al, 2005).…”

Stink bugs of the species Nezara viridula and Dichelops melacanthus are considered as some of the main insect pests associated with wheat production in Brazil. The use of the entomopathogenic fungus Metarhizium anisopliae might be an alternative for the management of these insects with chemical insecticides. Thus, the aim of this study was to evaluate and ascertain the pathogenicity of different isolates of M. anisopliae on N. viridula and D. melacanthus adults under laboratory and greenhouse conditions. In the laboratory, the fungal isolates 05RA, 11RA, 08RA, and 02RA, which were collected in the field from adults of N. viridula and D. melacanthus infected with M. anisopliae, were highly pathogenic, leading to 100% mortality in adults of N. viridula and D. melacanthus at 8 days after application (DAA). However, the isolate 08RA presented higher pathogenicity in a shorter period of time for N. viridula (mean mortality time "MMT" = 2.8 days) and D. melacanthus (MMT = 4.0 days) than the remaining isolates. At the greenhouse, the isolate 08RA led to a mortality of 44.9% (N. viridula) and 35.7% (D. melacanthus) at eight DAA; however, the mortality was 100% for both species at 14 DAA, with an MMT of 8 and 10 days for N. viridula and D. melacanthus, respectively. The fungus M. anisopliae constitutes a promising alternative agent to control the growth of adult populations of N. viridula and D. melacanthus in wheat cultures.
