| The toxicity of thiamethoxam and imidacloprid to Podisus nigrispinus (Dallas) nymphs, and their efficacy against whitefly and cotton aphid were studied. Thiamethoxam and imidacloprid were 217.6 and 223.4 and 1435.2 and 346.8 times more toxic (LC90) by ingestion than by residual contact to 2nd- and 5th-instar nymphs of this predator, respectively. Nymphs caged on potted cotton plants and treated with either insecticide at 1 mg (a.i.) per plant or more had lower survival than those on untreated plants, up to day 52 after treatment. Thiamethoxam and imidacloprid reduced field survival of P. nigrispinus compared to untreated plants up to nine days after treatment. Thiamethoxam and imidacloprid showed significant control of whitefly in comparison with untreated... |

| Reproduction and longevity of Supputius cincticeps (Stål) (Heteroptera: Pentatomidae) fed on Zophobas confusa Gebien, Tenebrio molitor L. (Coleoptera: Tenebrionidae) or Musca domestica (L.) (Diptera: Muscidae) larvae were studied during two generations at 24.7 ± 1.1ºC, 70 ± 10% R.H. and 12 h of photophase. Body weight of newly-emerged adults, oviposition period, number of egg masses, total number of eggs and longevity of S. cincticeps were higher when fed on Z. confusa or T. molitor larvae than on M. domestica larvae. Regardless of diet, S. cincticeps showed better reproduction and longevity in the second generation in laboratory conditions. |
