Optimal oviposition theory predicts that female herbivores prefer to oviposit on those plants that maximize offspring performance, also known as the “mother knows best” paradigm. This is the general pattern within the insect order Lepidoptera with specialist diets and reduced larval mobility. In that context, mother's decisions are crucial to the development of the offspring. In this review, we discuss oviposition-site selection behavior by the Heteroptera, focusing on the particular traits of this taxon in comparison with the most studied holometabolous insects. This review takes a multitrophic perspective and focuses on three main factors affecting the behavioral ecology of oviposition-site selection in true bugs: (1) life-history characteristics of the bugs, including host-plant specialization and mobility of larvae; (2) plant characteristics, including morphology and induced responses to feeding and oviposition, and (3) interactions with natural enemies, including parasitoid foraging behavior and strategies of bugs to interfere with the activity of parasitoids. New insights to the “mother knows best” paradigm of the behavioral ecology of oviposition-site selection by insects are provided by comparing the oviposition decisions displayed by true bugs with those of the well-studied Lepidoptera. The review ends with the identification of questions to be addressed in future studies on the behavioral ecology of oviposition by insects. |

Abstract:
Context: Environmental conditions during hot weather decrease feed intake and cattle growth.
Aims: This study conducted over three consecutive years, during the summer, evaluated access to shade as a strategy to mitigate heat stress of finishing cattle in Uruguay.
Methods: Each year, 32 Bos taurus and/or Bos taurus crossbred steers (initially weighing 461 ± 28 kg) were blocked by initial liveweight and assigned to one of eight pens, where one of two treatments were applied, namely, no shade access or shade access (mean shaded area 4.5 m2/animal). Finishing diet was offered three times per day and cattle had ad libitum access to water. Twenty-four pens were considered in a randomised complete-block design. Average daily gain (ADG), dry matter intake (DMI) and feed efficiency were measured, and hot carcass weight was collected at slaughter. Ruminal pH and temperature were obtained using ruminal boluses. Feeding, drinking, rumination, inactive behaviours, respiration rate and painting score were observed.
Key results: Mean days on feed were 70.6 ± 5.5. The average THI ranged from 70 to 72. Steers with access to shade had greater DMI (P = 0.003), ADG (P = 0.004), and feed:gain ratio (P = 0.05) than did not shaded steers. Ruminal pH was higher (P < 0.0001) in shaded than in not shaded animals. The slaughter weight of shaded steers was 10 kg greater (P = 0.02) than that of not shaded steers. A trend (P = 0.06) to higher hot carcass weight after dressing was obtained by shaded steers. The average respiration rate and panting score was consistently lower (P < 0.0001) for shaded than for not shaded steers, except in the early morning. Access to shade increased the time spent by animals feeding (P = 0.008) and ruminating (P = 0.001), decreasing inactive time (P < 0.0001).
Conclusions: Shade could improve performance and welfare of feedlot cattle during summertime, even in regions with an average THI from 70 to 72.
Implications: Access to shade allowed fattening cattle to dissipate heat stored during the day at night and to alleviate the effect of heat load during summer in subtropical region. MenosAbstract:
