For protection of domestic cattle, feeds should contain <0.05 mg diflubenzuron/kg FW. Cottonseed may be added to cattle diets provided that diflubenzuron concentrations in the seed do not exceed 0.2 mg/kg FW and that cottonseed composes <17% of the total diet bulk (Gartrell 1981). Diflubenzuron causes biochemical upset, as judged by lowered testosterone levels in chickens and rats (USEPA 1979), altered glutathione 5-transferase activity in mouse liver (which adversely affects the ability to detoxify foreign substances by way of conjugation Young et al. 1986), and disrupted hydroxylamine activity in human infants (USEPA 1979). Additional research seems needed on biochemical alterations induced by diflubenzuron. No diflubenzuron criteria are currently recommended for protection of avian and mammalian wildlife. All data available suggest that wildlife species are about as tolerant to diflubenzuron as are domestic poultry and livestock however, the wildlife database seems inadequate for practicable criteria formulation. [Pg.1015]

Data are scarce on the toxicity of PCP to mammalian wildlife, but studies with livestock and small laboratory animals show that the chemical is rapidly excreted. However, there is great variability between species in their ability to depurate PCP, as well as in their overall sensitivity. Acute oral LD50 values in laboratory animals were 27 to 300 mg/kg BW. Tissue residues were elevated at dietary levels as low as 0.05 mg/kg feed and at air levels >0.1 mg/m3. Histopathology, reproductive impairment, and retarded growth were evident at doses of 0.2 to 1.25 mg/kg BW, and when the diets fed contained >30 mg PCP/kg. [Pg.1204]

It has been suggested, but not yet verified, that many small mammals avoid arsenic-supplemented feeds and consume other foods if given the choice (NAS 1977), and that cacodylic acid, which has negligible effects on wildlife, reduces species diversity due to selective destruction of vegetation (Hood 1985). Both topics merit more research. [Pg.1523]

Birds are not the only creatures that come to a garden to feed. An organic garden is likely to provide rich pickings for both vegetarian and carnivorous wildlife visitors of all shapes and sizes. With a little extra thought, you can provide them with even better fare. Natural foods that can easily be included on the menu for wildlife include nectar, pollen, aphids, caterpillars, slugs, berries, and seeds. [Pg.114]

A pond, even a tiny one, can be the heart of your wildlife oasis. Your pond will be used by a wide range of creatures for many and various purposes. Some will drink from it, or hunt for food over it. Others will use it for cover, and feed and breed in it. Some will spend their whole lives in the pond, while others will use it for only part of their life cycle. [Pg.118]
