ABSTRACT

The chemotactic responses of Meloidogyne incognita were studied in salt gradients in an agarose gel. Forty-eight combinations of sodium, copper, cesium, manganese , barium, potassium, ferric or ammonium cations and chloride, nitrate, sulphate, hydrogen-phosphate, bicarbonate, acetic acid, thiocyanic acid and hydroxyl anions were tested at six concentrations from 0.0625 × 10-2 to 2 × 10-2 mol·L-1. M. incognita was repellented to salts that included Cl- and SCN-. Other salts that comprised the same anions had different chemotactic responses, among which M. incognita was repellented to ammonium salts that included Ba(NO3)2, NH4NO3, Mn(NO3)2, and hydrogen-phosphate salts that included KH2PO4, K2HPO4, and bicarbonate salts that included Na2CO3, K2CO3, (NH4)2CO3, KHCO3, and hydroxyl salts that included KOH, NaOH, and organic acid that included C2H4O2, C3H6O3 and C4H6O6. The repellent or attraction properties of different salts having the same cations were not consistent. The order of repellence was SCN- > NO3- > Cl- > OH- > CO32- >H2PO-4 > organic acid >SO42- . The chemotaxis of nematodes to KCl, Ba(NO3)2, NH4NO3, Mn(NO3)2, (NH4)2CO3, CH3COOH and C4H6O6 increased with the increasing concentration, while the concentration of other salts tested did not influence nematode chemotaxis significantly.
