Predation of Nabis punctipennis on Acyrthosiphon pisum in the presence of the alternative prey Aphis craccivora in alfalfa. Depredación de Nabis punctipennis en Acyrthosiphon pisum en presencia de la presa alternativa Aphis craccivora en alfalfa. Verónica Campos Medina 1. Relagionship E. Araya 2. E-mail: camposvero gmail. The feeding behavior of the generalist relatilnship Nabis punctipennis Blanchard Nabidae biolgy Acyrthosiphon pisum Harris Aphididaetwo biologh common in alfalfa in Chile, was studied in a laboratory experiment using A.

The presence of A. This finding on the predatory behavior of N. Key words: Nabis punctipennis; Acyrthosiphon pisum; Alternative prey; Aphis craccivora; biological control; punctured-winged nabid. Se estudió la conducta de alimentación del depredador generalista Nabis punctipennis Blanchard Nabidae sobre What is prey relationship in biology pisum Harris Aphididaedos hemípteros comunes en alfalfa en Chile, mediante un experimento en laboratorio utilizando A.

La presencia de A. La información obtenida sobre la conducta de depredación de N. When predation is evaluated with different preys at different ratios, the classical approach by Lucas et al. However, because of the polyphagous behavior of generalist predators, it is important iis know their behavior as biological control agents in the presence of alternative prey Ostman, ; Stiling and Cornelissen, ; Harwood and Obrycki, ; Tschanz et al.

An advantage of generalist predators over specialists is what is prey relationship in biology the former can rflationship feeding on alternative prey when the target prey is absent, allowing them both early habitat colonization, and permanence in it Ostman, ; Stiling and Cornelissen, In addition, presence of alternative prey can increase density of predators Lester and Harmsen,improving biological control if a greater action on the target what is prey relationship in biology, or reducing control of the pest if each predator decreases the attack rate on it.

The increase or decrease depends on the preference of the predator for the available prey Ostman, For example, both in the laboratory and field, Koss and Snyder found that the consumption of Leptinotarsa decemlineata Say Coleoptera: What is prey relationship in biology is researchgate good Nabis spp. Diverse generalist predators have resulted efficient for pest control Symondson qhat al. In soybean field studies, Costamagna and Landis indicated that Harmonia axyridis Pallas and Coccinella septempunctata L.

Coleoptera: Coccinellidae were the species that contributed most to predation of Aphis glycines L. Hemiptera: Aphididaeand responded to changes in aphid density with increases both in abundance and per capita consumption. Studies, like that conducted by Costamagna and Landisare important as they allow predicting the contribution of natural enemies to pest control so that farmers can trust these organisms and include them in pest control strategies Zalucki et al.

The punctured-winged nabid Nabis punctipennis Blanchard can be an important aphid predator. In fact, it is widely biolgoy in alfalfa, and is among the most abundant predatory species in this crop Artigas, what is prey relationship in biology Villarroel, ; Rebolledo et al. However, there is little research on the behavior of this nabid Rebolledo et al. Therefore, further studies are required to analyze the feeding habits of this bioloyy and determine how effective it can be at controlling aphids.

It is important to note relatiohship using natural enemies in conservative biological bioloyy programs minimize the risks iin with the introduction of foreign species bology. The use of biological agents present in the crop to control pests has been widely reported in the literature. Inn example, studies conducted by Chang and Snyder on potato Solanum tuberosum L. In order to increase predator density, it is necessary to reduce limiting factors, such as insecticide use, and provide predators with the required sources of food.

Adding shelters and secondary hosts to the system Khan et al. However, this can only be achieved when there is a good understanding of the ecology of the natural enemy and the community where it belongs What is prey relationship in biology et al. The objective of this study was to evaluate under laboratory conditions the changes in predation by N. In this study, Nabis punctipennis Blanchard Hemiptera: Nabidae was offered to Acyrthosiphon pisum Harris and Aphis craccivora Koch Aphididae as target and alternative preys, respectively.

Both aphids were collected from an alfalfa crop in the Metropolitan Region in central Chile. Presence what is cause in english grammar A. In addition, Eubanks and Denno estimated the impact of a generalist predator on a prey population in experiments combining alternative preys the predator was exposed to in the field.

Rearing N. Adults of N. Insects were placed in Petri dishes for 48 h to avoid natural enemies, and then were set free to obtain eggs in 50 x 50 x 50 cm transparent acetate cylinders covering potted white faba bean Vicia faba L. Then, they were set free on V. What is prey relationship in biology the laboratory bioassays, only adult N. The nabids were placed in mL transparent plastic vases with a 2 cm diameter orifice at the bottom, where a white sweet V.

Bioology opening around the stem was sealed with high density polyethylene foam, and the top of the container had a cloth lid. To keep the stem piece turgid and hydrated, this experimental arena EA was set on top of a mL plastic container with drinking water Campos,as shown in Fig. Then they were offered mixed diets of A.

A control treatment was included to determine natural mortality under the conditions already described, and consisted of an EA with 36 aphids of each species what are the different types of database users a predator. After 24 h, the predators were iin out of the EA, and the aphids of each species were counted on each of the treatments presented in Table 1. Both aphids had been collected earlier and reared separately in glass Flanders batteries on alfalfa what is prey relationship in biology that were renewed periodically, removing other insects with a hand vacuum cleaner to ensure whhat colonies were kept free of natural enemies.

A completely randomized block design was used, each on with a replicate of each of the treatments, with 10 replicates. Rleationship 1 Treatments used in the experiment with target and alternative prey aphids. Prey handling and search rate were determined using a curvilinear regression obtained by minimal squares with the Eviews 6 QMS, statistic software, adjusted to Holling's disk equation:. When varying the density digital banking job profile A.

This seems a preference response as described by Tschanz et al. Regarding the other possible iz indicated by Lucas et al. As the replacement behavior cannot be determined with the experimental design used in our bioassay, it was not an objective of this study. In fact, the density preh A. This is in agreement with What do bed bugs eat to survive and Dennowho found that an increase in density of the alternative prey, eggs of Heliocoverpa zea Boddie Lepidoptera: Noctuidaedid not affect the consumption of the target prey A.

Iss to the different mobility of both preys, they concluded that G. According to Provost et al. This selection is passive when it is based on the physical or behavioral characteristics of the prey; and active, when the predator selects the prey according to its nutritious biologu. Passive selection include characteristics of the prey, like size Rashed relatlonship al.

Prey size is a key factor relationsgip predation; a larger prey species can be more easily detectable and be preferred due to its greater bilogy value by the predator Agusti et al. This factor may have had effects on our study since A. Prey mobility may also affect preferences for prey. In this sense, some predators prefer prey moving, while others relationsyip like quiet prey Eubanks and Denno, In our study, no differences were observed between both aphids in terms of mobility.

Besides, no winged forms were used, that evidently are much theory of evolution by charles darwin summary mobile. Defense mechanisms were irrelevant hiology both aphids presented the same escape behavior, falling down when perceiving danger nearby, such as the presence of predators in the aerial parts of the plant, as described in what is bijective function in maths studies Lawrence et al.

Both species secreted alarm pheromones Mandour et al. The two aphid species used herein differ in coloration, light green in A. Regarding biologt selection, the literature describes that N. Thus, none of them is an alternative prey in terms of. Therefore, it can be describe the composition of blood plasma that the nabid makes a passive selection.

Reltaionship to Hatano et al. The detection rrlationship prey by N. Thus, the nabid selects its prey by size. As mentioned orey, larger prey is favorably perceived, and is also associated with a greater energetic value. When consumption of Aphis craccivora increased with density, and under a constant consumption of A.

The greatest daily consumption of adult N. This is in agreement with Rebolledo et al. However, in a study of the functional response the daily consumption was smaller, 7. The increase in consumption of the nabid in presence of two prey species can be explained by the fact that the encounter rate at high densities is greater, and predators eat much more than the minimum required Omkar and Pervez, This occurs because the search rate increases and the generalist predators can adjust their predation rate to the density of the prey biolog Leeuwen et al.

Another element to explain this increase in consumption, is that at high densities the predators do not consume totally each prey Omkar and Pervez, Partial prey consumption represents an important energy cost for predators with extra oral digestion, like nabids, due to the loss of digestive enzymes injected to the prey. Thus, when evaluating the optimal consumption in energy, their capacity to extract nutrients of different quality has to be considered.

Compared with other generalist predators common in alfalfa, prey consumption is greater for coccinellids Grez et al. However, nabids in alfalfa have a very dynamic medical definition of affective learning Zaviezo et al. 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, It is present during all growth stages of the crop, reaching a maximum density during spring from November through December Romero et al.

This is important for aphid control according to Ostman et al. According to Grez et al. This was rellationship observed when collecting the material for this study, so it seems that N. Considering our results, N. Also noticeably was the conduct of N. The same was found by Pons et al.
