摘要:

The study of altitudinal distribution of theLantanalace bugTeleonemia scrupulosaStal. in the Anaimalai hills (Western Ghats), India showed that the tingids were well adapted to the warmer climatic conditions prevalent at lower altitudes. The pest poulation was highest during summer, while heavy precipitation resulted in a slight decrease.

摘要:

The efficacy in the field of a synthetic pyrethroid pour‐on formulation (Ectopor) was tested against species of ticks which infest camels in Kenya. The acaricide provided an excellent percentage tick control which slowly waned from 99% on the third day post‐treatment to 70%, 51 days post‐treatment. The residual protection was 11 days. The percentage of dead but attached ticks decreased from 55.88% on day 1 post‐treatment to 3.61% on day 16 post‐treatment. The ticks found to infest the camels at the experimental site wereRhipicephalus pulchellus, Amblyomma variegatum, Hyalomma truncatum, Rhipicephalus evertsiandRhipicephalus appendiculatus.

摘要:

Covering maize cobs by wrapping maize leaves around them reduced damage by rose‐ringed parakeets (Psittacula krameri) by 97% in the field and 82% in aviary experiments. Being hidden and camouflaged, the wrapped cobs may have escaped detection by birds and thus were not damaged. The wrapping treatment also provided some protection to uncovered cobs within the treated plot, possibly by reducing the density of visible cobs in this plot compared with the control. There was no adverse effect of the wrapping treatment on grain yield.

摘要:

Three days trapping of rodents every month for 1 year effectively controlled rodent population and activity in vegetable crops. Trapping indices of native field species,viz. Bandicota bengalensis, Rattus meltada, Golunda ellioti, Mus boodugaandM. platythrixas well as the species inhabiting both fields and houses,viz.ftrattusandM. musculusdecreased significantly. Live‐burrow count ofB. bengalensisother rat species and mice reduced by 90.3%, 90.3% and 85.8% respectively. Even 6 months after the last trapping in the fields (recovery period), the live‐burrow count was 76.3%, 79.0% and 73.2% lower than the corresponding initial count for the three categories of rodent burrows respectively.
