| ABSTRACT: Information on selective herbicide, including glyphosate that does not affect non-target organisms such as natural enemies, are important in integrated pest management programs in maize. The dose 13.94 L ha-1 of glyphosate was evaluated in females on 10 Trichogrammatidae species. A female of each Trichogrammatidae species was individually positioned per test tube with a card containing approximately 45 Anagasta kuehniella Zeller, 1879 (Lepidoptera: Pyralidae) eggs. For 48 h parasitism was allowed, and later the cartons were sprayed with the herbicide or with distilled water, for the control treatment. The glyphosate showed variable effects for parasitoids. The emergence of T. acacioi females was lower but that of T. atopovilia, T. demoraesi, and... |

| Podisus nigrispinus is a generalist predator naturally occurring in agricultural and forestry systems that effectively contributes to the population balance of phytophagous insects, especially defoliating caterpillars. Histological changes were evaluated in the salivary glands and midgut of P. nigrispinus caused by ingestion of systemic herbicide isoxaflutole. These predator females were fed with leaves of eucalyptus plants, Tenebrio molitor pupae or water, contaminated or not by herbicide. Salivary glands and midguts were dissected, processed and analyzed under a light microscope. Activity level and cell morphology of the salivary glands and midgut showed differences among insects fed on plants, contaminated water or pupae. The epithelia of the salivary... |
