Predation, functional response and demographic parameters of Orius albidipennis (Hemiptera:Anthocoridae) on Schizaphis graminum (Hemiptera:Aphididae): effect of host plant morphological attributes
<p>Plant attributes like leaf hairiness and trichome compactness diversely affect the biocontrol agents of phytophagous insect pests. In the current study, effect of physical plant features on life table characteristics and functional response of <em>Orius albidipennis </em>(Rueter) females feeding on <em>Schizaphis graminum </em>(Rondani) was investigated on two common wheat cultivars (Falat and Pishtaz) differing in leaf morphological features. The trichome density of wheat cultivars considerably influenced a broad spectrum of attributes related to the performance of <em>O. albidipennis</em>. The intrinsic rate of increase (<em>rm</em>) was significantly greater on Falat (0.09±0.006) than on Pishtaz (0.06±0.008) cultivar. Similarly, the net reproductive rate and finite rate of increase were greater on Falat (16.72±3.38 and 1.083±7.54) than on Pishtaz (8.08±2.04 and 1.067±9.49). Although <em>Orius </em>predators exhibited type III of functional response on both wheat cultivars, they had lesser searching efficiencies and higher handling times on Pishtaz than those on Falat cultivar. Moreover, the maximum attack rate (<em>T</em>/<em>Th</em>) was greater on Falat than on Pishtaz. Lesser maximum predation and greater handling time of the <em>Orius </em>predators on Pishtaz cultivar might be imputed to the significantly more condensed surface trichomes of its leaves than that of Falat leaves, which physically prevented movement of the <em>Orius </em>bugs and decreased prey encounter rate. Moreover, increase of trichome density negatively influenced on foraging behavior of the predatory bug. Females were also found to prefer wheat leaves with fewer trichomes as oviposition hosts. It seems that trichomes provided hinderance to the <em>orius </em>bug. To recapitulate, it could be stated that the efficiency of <em>O. albidipennis </em>in controlling <em>S. graminum </em>on wheat may be more beneficial in cultivars with lower trichome density.</p>
Food quality of Ephestia eggs, the aphid Rhopalosiphum padi and mixed diet for Orius majusculus
<p>We studied the food quality of the aphid <em>Rhopalosiphum padi</em> to the pirate bug <em>Orius majusculus</em> using <em>Ephestia</em> eggs as high‐quality comparison prey. Several performance parameters were tested on individuals that had been reared and maintained on each of the two single‐prey diets or on a mixed diet. All fitness parameters were lower in individuals fed aphids only, indicating poor food quality of this prey. Compared with the pure <em>Ephestia</em> egg diet, the mixed diet enhanced teneral mass, while adult survival and female starvation tolerance were negatively affected and all other traits were unaffected. Body protein proportions were constant across diets, whereas lipid proportion was low in the aphid treatment. Preference for aphids was lower following a monotypic aphid diet than when reared on <em>Ephestia</em> eggs or a mixed diet. The results confirm that <em>R. padi</em> is low‐quality food for <em>O. majusculus</em> as it is for other generalist predators, even though <em>O. majusculus</em> may contribute significantly to population suppression of the aphid.</p>
