“…Switching behaviour is a good strategy for coping with prey scarcity (Hassanzadeh Avval et al, 2018). S. syriacus 4 th instar larvae and adult females preferred A. gossypii, when two species of aphids were offered in equal proportions.…”

http://www.eje.cz Citrus tristeza closterovirus (Closterovirus: Closteroviridae) (Ayazpour et al., 2013). Chemical control is the main method used to control citrus aphids (Smaili et al., 2014). However, excessive use of insecticides reduces natural enemy populations and leads to resistance of the aphids to many common insecticides. Biological control is a safe alternative method for controlling aphids in citrus orchards (Alizadeh Kafeshani et al., 2018).Scymnus syriacus Marseul (Coleoptera: Coccinellidae) is a widely distributed species and is important in suppressing aphid abundance in citrus orchards (Allawi, 2006). Both larvae and adults actively search for leaves infested with aphids. They feed on many species of aphids, especially A. spiraecola and A. gossypii (Emami et al., 2004). The young larvae of S. syriacus usually suck out the contents of aphids, whereas adults eat the whole body of the aphids. The number of aphids consumed depends on the size of the aphid, developmental stage of the predator and environmental conditions, such as temperature. The mean number of aphids consumed by the larval stages of S. syriacus has reported to be 95 and 130 aphids at 25°C and 30°C, respectively (Allawi, 2006).

“…These characteristics led to considering spiders as potentially successful natural enemies. However, the extent to which they are actually efficient for pest limitation depends on a series of traits, such as prey preference [12], prey switching behavior [13], the habitat structure and environmental conditions [14], and the attack rate and prey handling time [15]. The last two parameters are widely studied through functional response experiments to describe the predator feeding rates at increasing prey densities.…”

Web Architecture Affects the Functional Response of the Space Web-Builder Kochiura aulica against Trioza erytreae in the Laboratory

2022

The “citrus greening disease” or huanglongbing (HLB) is caused by the Gram-negative bacteria Candidatus Liberibacter spp. One vector of HLB, the African citrus psyllid Trioza erytreae (del Guercio, 1918), was recorded for the first time in 2014, in mainland Spain, and since then, it has spread throughout the Iberian Peninsula. Spiders could be natural enemies of T. erytreae. In this work, we assessed the potential of a model spider species, selected according to the most abundant guild in the field, as a natural enemy of T. erytreae. Theridiidae was the most successful family, capturing adults of T. erytreae in the field. Kochiura aulica (Theridiidae) was selected as a model for functional response assays in the laboratory. The effect of web-building plasticity on the functional response of K. aulica was investigated using two types of arena. The spiders developed tubular-like or branch-like webs according to the spatial constraints. The web architecture significantly shifted the trapping efficiency of K. aulica. Functional responses for tubular and branch webs were both Type-II, but more psyllid prey were captured and killed in the tubular webs than in branch webs. In addition, significantly more psyllids survived in branch-like webs. Our results suggest that web architecture is a key factor driving the number of captured adults of the psyllid. Space web builders could be successful natural enemies of T. erytreae, although further research is needed to clarify the influence of web-building plasticity on the functional response and trapping efficiency of spiders.

“…When a predator has a weak preference, or no preference, for 1 of 2 prey species, the indirect effect of 1 prey species on the other will depend on the relative abundance of each prey species (Eubanks and Denno 2000, Banihashemi et al 2017, Hassanzadeh-Avval et al 2018). Some predators may shift prey preference according to the abundance of prey in the mixed prey system.…”

Presence of nontarget prey, Tetranychus truncatus, affected the predation by Neoseiulus bicaudus on Tetranychus turkestani

Neoseiulus bicaudus (Wainstein) (Acari: Phytoseiidae) is a generalist predatory mite that consumes several pest species, including Tetranychus turkestani (Ugarov et Nikolskii) (Acari: Tetranychidae) in the Xinjiang Uygur Autonomous Region. The release numbers of predatory mites are based on the populations of target pests and their ability to control them. Populations of T. turkestani and T. truncatus Ehara (Acari: Tetranychidae) often coexist and damage many crops. To determine whether the presence of the non-target prey T. truncatus affects the ability of N. bicaudus to control the target prey T. turkestani. The study evaluated the predation rate and functional response of N. bicaudus to 4 stages of T. turkestani in the presence of T. truncatus. The consumption of T. turkestani by N. bicaudus gradually decreased as the proportion of T. truncatus increased. The functional response of N. bicaudus to T. turkestani was not changed when T. truncatus was presented, which was consistent with a type II response. The attack rate of N. bicaudus on the egg, larva, and nymph of T. turkestani was significantly decreased and the handling time of N. bicaudus on T. turkestani was significantly extended when T. truncatus was presented. The preference index showed that the preference of N. bicaudus for eggs and female adults of T. turkestani decreased with increasing density of T. turkestani in the same proportion as T. truncatus. The presence of T. truncatus can negatively affect the predation of T. turkestani by N. bicaudus. We suggest that the number of N. bicaudus released to control T. turkestani should be increased when T. truncatus coexist.
