“…This likely was due to larval weight, since their weight increased from first to fourth instar. The toxic effect of pyrethroids on coccinellids has been reported by several authors (Tillman and Mulrooney 2000;Gusmão et al 2000;Michaud 2002;Torres and Ruberson 2005;Ruberson et al 2007;Rodrigues et al 2013). Olszak (1999) reported in a study with different stages of A. bipunctata, that pyrethroids were the most toxic compounds among the insecticides that were tested.…”

Coccinella septempunctata L. is one of the most abundant ladybird species in Greece, preying on several aphid species and other arthropods, of which many are pests of cultivated plants. These pests are usually controlled with chemical insecticides. During this process, however, beneficials are also exposed to pesticides. The development of Integrated Pest Management (IPM) programs against aphids requires the evaluation of the effects of insecticides on beneficial insects. We evaluated the LD 50 of imidacloprid, acetamiprid, bifenthrin and deltamethrin on first, second, third and fourth instar larvae of C. septempunctata by topical application. Moreover, we studied their sublethal effects (LD 10 ) on the development, weight and prey consumption of fourth instar larvae. The topical application bioassays showed that deltamethrin and bifenthrin were highly toxic to all larval instars, whereas imidacloprid and acetamiprid were less toxic to fourth instar larvae. The LD 10 dose significantly affected, developmental time, adult weight and daily predation. These results show the importance of assessing potential effect of insecticides on C. septempunctata for developing effective IPM programs of aphids in Greece.

“…When both BCA and its pest are affected by insecticide exposure, the differential susceptibility between both need not be large, just enough not to impair the numerical balance between the populations of natural enemy and pest (Rodrigues et al, 2013b). However, the resistance selected may be enough to achieve sufficient survival of resistant individuals exposed to the MFR of both neonicotinoids.…”

Imidacloprid and thiamethoxam are neonicotinoids that have been tested in several Orius species, including Orius laevigatus (Fieber) (Hemiptera: Anthocoridae), but not the variability in their effect among Orius populations of a single species. In this study, the variation in susceptibility to imidacloprid and thiamethoxam in 30 Mediterranean wild populations and four commercial populations of O. laevigatus was investigated in the laboratory using a standard dip bioassay method. Lethal concentration values (LC 50 ) and the mortality of adults at the maximum field rate (MFR) were calculated. The range of LC 50 of thiamethoxam was from 0.7 to 5.9 mg l À1 , an 8.4-fold variability, obtaining mortality at MFR (100 mg l À1 ) of >89.1% in all populations. The baseline obtained a value of 2.1 mg l À1 , which is very low compared to the MFR. For imidacloprid, the LC 50 varied from 7.7 to 94.7 mg l À1 (12.3-fold variability). Mortalities at the MFR (150 mg l À1 ) were 57.7-99.2%, that is, more variable than for thiamethoxam. The LC 50 value of the baseline was 48.7 mg l À1 , also low compared to the MFR. This variation was exploited to select two populations resistant to thiamethoxam and imidacloprid, respectively. Artificial selection for on average 40 cycles significantly increased the resistance to thiamethoxam (LC 50 = 149.1 mg l À1 ) and imidacloprid (LC 50 = 309.9 mg l À1 ). Mortalities at the MFR in the thiamethoxam-and imidacloprid-resistant populations were 44.5 and 36.9%, respectively. These results demonstrate that resistance can be enhanced in biocontrol agents by artificial selection under laboratory conditions, starting with populations showing no or very low tolerance. Our neonicotinoid-resistant populations might enhance the wider adoption of biological control by allowing punctual or hotspot applications of neonicotinoids to control several main and secondary pests.

“…Ecological theory predicts nonrandom species sorting in association with environmental filters, determined by species traits (Southwood 1977, Shipley et al 2006, Weiher et al 2011, Mouillot et al 2013. As functional features (i.e., within-taxon trait mean and variability) conferring stress tolerance arise in response to highly selective environmental filters (Buchwalter et al 2008, Rodrigues et al 2013, it is likely that some of the functional attributes of communities subjected to natural, long-term persistent stressors may be similar to those related to relatively new, short-term anthropogenic stressors. Furthermore, previous studies have documented that traits conferring natural stress tolerance can also grant a species the ability to tolerate novel stressors (Badyaev 2005, Buchwalter et al 2008, Arribas et al 2014.…”

The effect of stressors on biodiversity can vary in relation to the degree to which biological communities have adapted over evolutionary time. We compared the responses of functional features of stream insect communities along chronic stress gradients with contrasting time persistence. Water salinity and land use intensification were used as examples of natural (long-term persistent) and anthropogenic (short-term persistent) stressors, respectively. A new trait-based approach was applied to quantify functional diversity components and functional redundancy within the same multidimensional space, using metrics at the taxon and community levels. We found similar functional responses along natural and anthropogenic stress gradients. In both cases, the mean taxon functional richness and functional similarity between taxa increased with stress, whereas community functional richness and functional redundancy decreased. Despite the differences in evolutionary persistence, both chronic stressors act as strong nonrandom environmental filters, producing convergent functional responses. These results can improve our ability to predict functional effects of novel stressors at ecoloiical and evolutionary scales.
