“…It was fi rst reported on Crotalaria sp. in Rio de Janeiro state (Costa Lima 1919 ), and other hosts include common bean, soybean, cotton, tomato, lupin, pigeon pea, and lablab (Panizzi 1988 ;Chandler 1989 ;Santos and Panizzi 1998a ). Eggs ( Fig.…”

“…Several studies on the nymphal and adult biology, population dynamics, oviposition, and feeding preferences of N. parvus on selected cultivated and noncultivated legumes (e.g., soybean, pigeon pea, lablab, green bean, indigo, lupin, and cowpea) have been published (Panizzi 1988 ;Ventura and Panizzi 1997 ;Santos and Panizzi 1998a ;Ventura et al 2000a , b ;Ventura and Panizzi 2003, 2004, 2005. In general, this alydid is most associated with mature soybean and pigeon pea plants.…”

The broad-headed bugs (Alydidae) are divided into two subfamilies, Alydinae and Micrelytrinae, each divided into two tribes, Daclerini and Alydini, and Micrelytrini and Leptocorisini, respectively. The family has 53 genera and about 250 species; in the Neotropics, there are 21 genera. Alydids are small (8-20 mm), slender, with a triangular head; nymphs of alydines mimic ants, the adults of some Micrelytrini also mimic ants. The most studied species in the Neotropics is the alydine Neomegalotomus parvus (Westwood), usually associated with legumes, and may be a pest on soybean. Other common genera include Hyalymenus Amyot & Serville, Stenocoris Burmeister, Cydamus Stål, and Trachelium Herrich-Schäffer. Studies on taxonomy and bioecology on alydids of the Neotropics are needed.

“…parvus has been adapted to various leguminous crops such as lablab beans, Dolichus lablab L. [7], pigeon pea, Cajanus cajan (L.) Mill., pig bean, Canavalia ensiformis (L.) DC., and indigo, Sesamum indicum L. [8,9]. However, it is the common bean, Phaseolus vulgaris L. [10,11] and soybean, Glycine max (L.) Merrill [12], that this bug is an economically important pest.…”

“…Santos and Panizzi [12] showed that artificial infestation of soybean plants during the podfiling stage causes a reduction in seed vigor and viability and has a negative effect on seed quality when infestation is in advanced stage. However, asynchrony between vulnerable stages of soybean seed development and N. parvus populations allows soybean crops to usually escape severe injury from this insect in the field [9].…”

The Neotropical broad-headed bug, Neomegalotomus parvus (Westwood), is adapted to various leguminous crops and is considered a pest in common bean and soybean. The chemical communication of this species was studied in order to identify an attractant pheromone. Males and females of N. parvus produce several short-chain esters and acids, and their antennae showed electrophysiological responses to five of these compounds, three common to both sexes (hexyl butanoate, 4-methylhexyl butanoate, and hexyl hexanoate), and two female-specific compounds (4-methylhexyl pentanoate and hexyl pentanoate). Both aeration extracts of females and a solution containing five synthetic compounds mimicking the natural blend were attractive to males and females N. parvus in a laboratory bioassay. Aspects of the chemical ecology of the broad-headed bugs and the possibility to use pheromone-baited traps in the field for monitoring are discussed.

“…In the neotropics, members of Neomegalotomus (formerly Megalotomus), a genus indigenous to the neotropics and subneotropics, have become occasional pests on various leguminous crops, such as lablab (Santos & Panizzi 1988a), common bean (Paradela Fº et al 1972), and pigeon pea (Santos & Panizzi 1998b). However, these bugs are more important as pests of soybean, Glycine max (L.) Merrill (Santos & Panizzi 1998b, Panizzi et al 2000.…”

Neotropical Entomology 36(2): 320-321 (2007) O Nome Correto do Percevejo Neotropical da Soja (Hemiptera: Alydidae) RESUMO -Uma espécie de Neomegalotomus é praga ocasional de soja [Glycine max (L.) Merrill] na Região Neotropical, incluindo o Brasil. Essa espécie era conhecida como Neomegalotomus parvus (Westwood); entretanto, a descoberta da espécie tipo de uma outra espécie, descrita anteriormente, requer que o nome seja trocado para Neomegalotomus simplex (Westwood), o que o torna o nome correto para essa praga da soja. PALAVRAS-CHAVE: Espécie tipo, Neomegalotomus, Glycine maxABSTRACT -A species of Neomegalotomus is an occasional pest of soybean [Glycine max (L.) Merrill] in the neotropics, including in Brazil. It was known as Neomegalotomus parvus (Westwood); but the discovery of the type specimen of a species described earlier requires that the name be changed to Neomegalotomus simplex (Westwood), which becomes the correct name for the soybean pest.
