“…(Heteroptera: Alydidae) (Panizzi, 1988;Ventura and Panizzi, 1997;Santos and Panizzi, 1998). Ventura and Panizzi (2004) showed that males of N. parvus attract the same species in the field. This aggregation pheromone of N. parvus was identified and positive field responses were also obtained (W. Leal and A.R.…”

“…In previous studies, green vessel water traps caught more male N. parvus than traps of other colors, except yellow. Yellow traps also caught more insects than blue, black, and silver traps (Ventura and Panizzi, 2004). A positive interaction between trap color and attractant was also reported for Diabrotica virgifera virgifera LeConte (Hesler and Sutter, 1993) and D. speciosa Germar (ArrudaGatti et al, 2006).…”

“…This behavior may occur in the absence of major hosts, i.e., leguminous plants (Schaefer, 1980;Schaefer and Mitchell, 1993). Adults and nymphs were found feeding on conspecific nymphs and adult cadavers (Ventura and Panizzi, 2004). These authors also reported that second instar nymphs deprived of leguminous seeds, fed exclusively on dead nymphs and reached the third instar, demonstrating the importance of the alternative food for N. parvus nutrition.…”

The alydid bug parvus (Westwood) is not easily detected in the field and the discovery of attractants may be a suitable way to monitor this species. The attraction of N. parvus to traps (transparent, transparent green and yellow) baited with cow urine and ammonia was studied in two field trials. Traps were placed near a terrace with pigeon pea plants (Cajanus cajan L.). Tap water, NaCl 10% aqueous solution (w/v), cow urine, and ammonia (NH 4 OH 1% aqueous solution) were tested as attractants in yellow, transparent and transparent green traps. Green traps baited with cow urine caught more bugs than yellow and transparent traps (3.2 and 7.2 times more, respectively), and more bugs than traps of the same color with just water (no captures) or NH 4 OH solution (14.5 times more). Traps baited with ammonia caught more bugs than traps with water: 14.4, 4.7 and 6.7 times more than transparent green, yellow, and transparent traps, respectively, or NaCl solution: 3.9, 7.6 and 6.2 times, respectively. Both ammonia and cow urine are attractive to N. parvus and may be tested to monitor the bugs in the field. Key words: semiochemical, attractant, trap color Atração de Neomegalotomus parvus (Westwood) (Heteroptera: alydidae) por urina de vaca e amônia RESUMO: O percevejo alidídeo Neomegalotomus parvus (Westwood) não é facilmente detectado no campo e a descoberta de atraentes pode ser uma forma adequada para monitorar a espécie. A atração de N. parvus a armadilhas (transparentes, verde transparente e amarela) iscadas com urina de vaca e amônia foi estudada em dois experimentos em campo. Armadilhas foram colocadas próximas a um terraço com plantas de feijão-guandu (Cajanus cajan L.). Água corrente, solução aquosa de NaCl 10% (p/v), urina de vaca e amônia (solução aquosa de NH 4 OH 1%) foram testadas como atraentes em armadilhas amarelas, transparentes e transparentes verdes foram utilizadas. Armadilhas verdes iscadas com urina capturaram mais insetos do que armadilhas amarelas e transparentes (3,2 e 7,2 vezes mais, respectivamente), e mais insetos do que armadilhas da mesma cor com apenas água (zero insetos) ou solução de NaCl (14,5 vezes mais). Armadilhas iscadas com amônia capturaram mais insetos do que armadilhas com água: 14,4; 4,7 e 6,7 vezes mais em verde transparente, amarela e transparente, respectivamente, ou solução de NaCl: 3,9; 7,6 e 6,2 vezes, respectivamente. Amônia ou urina de vaca são atrativas para N. parvus e podem ser testadas para monitorar o percevejo no campo. Palavras-chave: semioquímicos, atraente, cor de armadilha

“…For N. parvus, traps baited with live males captured significantly more males that unbaited traps [23]. In addition, it is known from field observations that some bugs are attracted to cow urine [24], and traps baited with cow urine or NH 4 OH solutions captured N. parvus in the field [25].…”

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.
