Conservative biological control promotes the use of native natural enemies to limit the size and growth of pest populations. Although spiders constitute one of the most important groups of native predators in several crops, their trophic ecology remains largely unknown, especially for several generalist taxa. In laboratory, we assessed the predatory behaviour of a wandering spider (the wolf spider Lycosa thorelli (Keyserling, 1877) against several arthropods varying in size and trophic positions, all found in South American soybean and rice crops. As prey we used the bug Piezodorus guildinii (Westwood, 1837) as well as larvae and adults of the moth Spodoptera frugiperda (Smith, 1797), both being considered important pests in Uruguayan crops. We also used several non‐pest arthropods as prey, sarcophagid flies, carabid beetles and wolf spiders. All prey were attacked in more or less high, although not statistically differing, proportions. However, carabids were not consumed, and bugs were consumed in significantly lower proportions than flies. A negative correlation was found between prey size and acceptance rate. Immobilization times were longer against larvae when compared to moths and flies, while predatory sequences were longer for bugs when compared to flies, moths and spiders. In addition, we found a positive effect of prey size on predatory sequence length and complexity. Our results confirm the ability of spiders to attack and feed upon prey with different morphologies, included well‐defended arthropods, and their potential use as natural enemies of several pests in South American crops.

ABSTRACT.- Potential trade-off among weaning (WWT) and yearling weights (YWT), greasy fleece weight (GWT) genetic resistance to gastrointestinal nematodes assessed by faecal worm egg account (FEC), residual feed intake (RFI) and methane (CH4) and carbon dioxide (CO2) emissions were investigated in 217 Corriedale female lambs. Improving RFI was strongly associated with lower dry matter intake (DMI) and independent of metabolic body weight (MWT) and average daily gain (ADG). Person correlation coefficients were also no significant (P>0.05) with WWT, YWT, GFW and FEC expected progeny differences (EPD). FEC EPD was not correlated with any of the traits investigated here. Both CH4 and CO2 were not associated with RFI, although the moderate correlations with DMI. Higher EPD for WWT, YWT and GFW were correlated with higher DMI, CO2 and CH4. Optimising higher productivity and environmental sustainability requires further research for a more comprehensive understanding of these associations. |
