“…Compared with other generalist predators common in alfalfa, prey consumption is greater for coccinellids (Grez et al, 2007;Sarmento et al, 2007) than N. punctipennis, including Eriopis connexa (Germar), Adalia bipunctata (L.), and Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) (Zaviezo et al, 2004(Zaviezo et al, , 2006. However, nabids in alfalfa have a very dynamic presence (Zaviezo et al, 2004;Rebolledo et al, 2009). Thus, even though consumption per capita of the nabid is not too high, it has important characteristics, like being the predator most frequent in alfalfa in the Metropolitan Region (Villarroel, 2001).…”

RESUMENSe estudió la conducta de alimentación del depredador generalista Nabis punctipennis Blanchard (Nabidae) sobre Acyrthosiphon pisum Harris (Aphididae), dos hemípteros comunes en alfalfa en Chile, mediante un experimento en laboratorio utilizando A. pisum y Aphis craccivora Koch (Hemiptera: Aphididae) como presa alternativa, otro áfido común en alfalfa. La presencia de A. craccivora no afectó la depredación de A. pisum por N. punctipennis. La información obtenida sobre la conducta de depredación de N. punctipennis es valiosa para evaluar su potencial como agente de control biológico de A. pisum.Palabras clave: Nabis punctipennis, Acyrthosiphon pisum, Aphis craccivora, nábido de alas punteadas, presa alternativa, control biológico. ABSTRACTThe feeding behavior of the generalist predator Nabis punctipennis Blanchard (Nabidae) on Acyrthosiphon pisum Harris (Aphididae), two hemipterans common in alfalfa in Chile, was studied in a laboratory experiment using A. pisum, and Aphis craccivora Koch (Aphididae) as alternative prey, which is another common aphid in alfalfa. The presence of A. craccivora did not affect the predation of A. pisum by N. punctipennis. This finding on the predatory behavior of N. punctipennis is valuable to evaluate the potential of this nabid as a biological control agent of A. pisum.

“…Summers (1976) and Wheeler (1977) observed that populations of lady beetles in an alfalfa field in California and New York were high in May and September. More recently, a noticeable increase in a H. variegata population in early autumn was reported by Rebolledo et al (2009) from Chile. As in the present study, Rakhshani et al (2009) reported the peak of H. variegata on July 21 in the province of Isfahan (Central region of Iran), and their study confirms our results about the higher level of H. variegata.…”

Abstract:Two important lady beetle species commonly found in alfalfa fields in Iran are the variegated lady beetle Hippodamia variegata Goeze and the seven spotted lady beetle Coccinella septempunctata (Linnaeus, 1758) (Coleoptera: Coccinellidae). These two species attack many aphid species including the pea aphid, Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae). In this study, the seasonal population changes of A. pisum, H. variegata, C. septempunctata and the parasitoid, Dinocampus coccinellae (Schrank) (Hymenoptera: Braconidae) were studied in alfalfa fields in the 2012 and 2013 seasonal periods. The highest ladybird densities were noted on July 5, 2012 and on September 6, 2013 (17.2±2.8 and 13.4±1.6) individuals per 20 sweeps, respectively. Parasitism rates by D. coccinellae ranged from approximately 3 to 6% in two subsequent years, respectively. Parasitism was higher early in the growing season. Most parasitised ladybirds were females. There was no significant relationship between the temperature and relative humidity with pea aphid populations, although the aphid populations declined during the hot summer period. In contrast, the relationship between temperature and the H. variegata population was significant and positive in both years of the study. It has been shown that these lady beetle species have a major role in reducing the pea aphid populations in alfalfa fields. Due to the relatively low percentage of field parasitism by D. coccinellae, this parasite might not reduce the biocontrol efficiency of lady beetle species.

“…However, their presence in alfalfa is very dynamic (Zaviezo et al, 2004;Rebolledo et al, 2009). Although the nabid per capita consumption is not high, it is the most common predator in alfalfa in the Metropolitan Region throughout crop growth, reaching maximum density in the spring, from November through December (Romero et al, 2007).…”

RESUMENSe analizó la conducta de depredación de hembras adultas de Nabis punctipennis Blanchard (Nabidae) hacia Acyrthosiphon pisum Harris (Aphididae) en laboratorio para determinar su respuesta funcional y su potencial como agente de control biológico de este áfido. Ambos hemípteros son comunes en alfalfa, Medicago sativa L., en Chile. Las hembras de N. punctipennis presentaron una respuesta funcional tipo II, con un tiempo de manipulación de 2,757 ± 0,1181 h presa -1 y una tasa de búsqueda de 0,353 ± 0,3214 h -1 .Palabras clave: pulgón de la alfalfa, respuesta funcional, control natural, nábido de alas punteadas. ABSTRACTThis study analyzed the predatory behavior of adult females of Nabis punctipennis Blanchard (Nabidae) towards Acyrthosiphon pisum Harris (Aphididae) in the laboratory in order to determine its functional response and potential as a biological control agent of this aphid. Both hemipterans are common in alfalfa, Medicago sativa L., in Chile. The females of N. punctipennis presented a type II functional response, with a handling time of 2.757 ± 0.1181 h prey-1 and a searching rate of 0.353 ± 0.3214 h -1 .
