Experiments with BHC, chlordane, and parathion against the lucerne flea (Sminhurus viridis (L.)) and the red-legged earth mite (Halotydeus destructor (Tuck.)) in pastures are described. All insecticides were applied by means of a low-volume boom spray delivering 5 gal per acre. BHC applied at the rate of 2 lb 50 per cent. dispersible powder per acre had no effect on the lucerne flea population but killed approximately 90 per cent. of the earth mites present. Chlordane applied a t the rate of ½ lb per acre achieved no control of either pest. Parathion applied at the rate of ¼ pt of 20 per cent. emulsion per acre gave practically 100 per cent. control of lucerne fleas. Its residual effects were negligible and fleas hatching from eggs laid prior to spraying were not harmed. Equally good immediate control was achieved by applications of parathion at one-half the above concentration. The addition of DDT to the spray ensured the destruction of all earth mites as well as the lucerne flea. DDT gave no evidence of control of the lucerne flea in previous experiments. The experiments show that parathion is a highly effective insecticide against the lucerne flea but for maximum efficiency it should be applied early in the season before any eggs have been laid. The toxicity of the parathion sprays to grazing stock is discussed.

Heavy Infestation

In Florida, clustered pellitory is becoming a troublesome weed for citrus, especially from the winter through early summer. Inadequate management of this weed can result in its heavy infestation in tree rows and can interrupt the spray pattern of low-volume drip irrigation systems. This new 3-page publication of the UF/IFAS Horticultural Sciences Department will assist Florida citrus growers with proper identification of clustered pellitory and with adoption of adequate and timely strategies to manage this weed in their groves.

Population dynamics and life history traits of the ‘giant’ limpet Scutellastra laticostata on intertidal limestone platforms at Rottnest Island, Western Australia, were recorded by interannual (January/February) monitoring of limpet density and size structure, and relocation of marked individuals, at 3 locations over periods of 13-16 yr between 1993 and 2020. Limpet densities ranged from 4 to 9 ind. m-2 on wave-swept seaward margins of platforms at 2 locations and on a rocky notch at the landward margin of the platform at a third. Juvenile recruits (25-55 mm shell length) were present each year, usually at low densities (<1 m-2), but localized pulses of recruitment occurred in some years. Annual survival rates of marked limpets varied among sites and cohorts, ranging from 0.42 yr-1 at the notch to 0.79 and 0.87 yr-1 on the platforms. A mass mortality of limpets on the platforms occurred in 2003, likely mediated by thermal stress during daytime low tides, coincident with high air temperatures and calm seas. Juveniles grew rapidly to adult size within 2 yr. Asymptotic size (L∞, von Bertalanffy growth model) ranged from 89 to 97 mm, and maximum size from 100 to 113 mm, on platforms. Growth rate and maximum size were lower on the notch. Our empirical observations and simulation models suggest that these populations are relatively stable on a decadal time scale. The frequency and magnitude of recruitment pulses and high rate of adult survival provide considerable inertia, enabling persistence of these populations in the face of sporadic climatic extremes.
