| effect of air humidity on the egg viability of predatory mites (acari: phytoseiidae, stigmaeidae) common on rubber trees in brazil. | rubber pest mites, calacarus heveae and tenuipalpus heveae, reach economic damage levels at the end of the rainy season and the beginning of the dry season in brazil. therefore, low humidity adaptation might be an important characteristic for predatory mites to successfully control pest organisms. this study determined the effect of the relative humidity (rh) levels of 30-100% on the hatching of larvae of amblyseius acalyphus, euseius citrifolius, iphiseiodes zuluagai, metaseiulus camelliae, agi ... | 2006 | 16550332 |
