Temperature-dependent functional response of Scolothrips longicornis (Thysanoptera: Thripidae) preying on Tetranychus urticae

Temperature-dependent functional response of Nesidiocoris tenuis (Hemiptera: Miridae) to different densities of pupae of cotton whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae)

“…One way of evaluating such features is to study its foraging behaviour, such as its functional response to prey density (Pakyari et al, 2009;Salehi et al, 2016). The functional response of predators is affected by several factors among which temperature is known to be an important abiotic driver.…”

Estimating development and temperature thresholds of Scolothrips longicornis (Thysanoptera: Thripidae) on eggs of two-spotted spider mite using linear and nonlinear models

“…The latter species has been reported from several regions including the Middle East, India, and North America (Priesner 1950;Gilstrap and Oatman 1976;Alavi and Kamali 1995) and was reported for the first time from Iran in 1995 by Alavi and Kamali. S. longicornis is common in bean (Aydemir and Toros 1990), cucumber, and eggplant fields (Pakyari andFathipour 2009a, 2009a) and has been demonstrated to be an important predator of several spider mite species (Chazeau 1985;Aydemir and Toros 1990) with a seasonal abundance correlated with that of the pest (Kheradpir et al 2008). Life table characteristics of S. longicornis preying on the carmine spider mite (Tetranychus cinnabarinus Boisd.)…”

“…were investigated by Sengonca and Weigand (1988), who in addition documented the high predation capacity of both larval and adult thrips on eggs of the spider mite prey. Other studies have demonstrated that S. longicornis is adapted to warm climates and that the high predation capacity also pertains to nymphal and adult spider mites (Gerlach and Sengonca 1986;Pakyari et al 2009), although the predator, at least when feeding on the two-spotted spider mite (Tetranychus urticae Koch), has a preference for eggs over nymphs and adults (Pakyari and Fathipour 2009a). Apart from a few studies on functional response (Gotoh et al 2004a;Pakyari et al 2009) and mutual interference (Pakyari and Fathipour 2009b) details in the biology, including information on temperature-dependent development, of S. longicornis predating on T. urticae have not been published.…”

FUNCTIONAL RESPONSE OF Nabis punctipennis Blanchard to Acyrthosiphon pisum Harris IN THE LABORATORY

“…However, other unconsidered factors could affect the functional response, for example: how hungry the predator is, age (Siddique, 1985), learning (Morales et al, 2001), size of the predator and prey, prey defense strategies (Villagra et al, 2002;Sarmento et al, 2007), and its distribution (Pitt and Ritchie, 2002), as well as environment factors like temperature (Gitonga et al, 2002;Pakyari et al, 2009). To prevent these factors from affecting the functional response of the nabid, the bioassays were conducted only with 10-15 d-old adult females, which were kept with no food for 24 h to level their gut content.…”

“…Hollings´s disk equation (Skalski and Gilliam, 2001) is commonly used to characterize the response of generalist predators to an increase in prey density (Ma et al, 2005;Pakyari et al, 2009), assuming that predators search for prey at random, with a fixed encounter probability (Fernán-dez and Corley, 2004). Using the disk equation, Ma et al (2005) found that the consumption of Plutella xylostella (L.) (Lep.…”
