Emergence Of Resistance

Although being of less importance to the incidence of the vector-borne disease than mosquitoes, houseflies (Musca domestica) are mechanical transmitters of the disease. The chemical control carried out until now has brought about the emergence of resistance of houseflies against DDT and many other insecticides including organophosphates and carbamates. In order to look for an alternative insecticide which can control houseflies, a study was performed on the efficacy of insecticide belonging to the synthetic pyrethroid group containing 30 g/l of the active substance such as alphacypermethrin. Four dosages of insecticide with active ingredient of 30 g/l alphacypermethrin at dosages of 17.5 ml/ha, 35 ml/ha, 50 ml/ha and 70 ml/ha respectively wereused by fogging against houseflies kept in cages. The result showed that dosages of 35 ml/ha, 50 ml/ha and 70 ml/ha were all effective to kill M. domestica.

Crop Competition

Successful weed control in small grains involves using good management practices in all phases of production. In Florida, winter weeds compete with small grains for moisture, nutrients, and light, with the greatest amount of competition occurring during the first six to eight weeks after planting. Weeds also cause harvest problems the following spring when the small grain is mature. This 4-page publication discusses crop competition, knowing your weeds, and chemical control. Written by J. A. Ferrell, G. E. MacDonald, and P. Devkota, and published by the UF/IFAS Agronomy Department, revised May 2020.

First Time

Drosophila suzukii (Diptera, Drosophilidae) is an exotic species, endemic to Asia and currently a pest to small and stone fruits in several countries of North America and Europe. It was detected in 2013 for the first time in South America, in the south of Brazil. Unlike most drosophilids, this species deserves special attention, because the females are capable of oviposit inside healthy fruits, rendering their sale and export prohibited. Despite the confirmed existence of this species in different states of Brazil, this insect is yet been to be given the pest status. Nevertheless, the mere presence of this species is enough to cause concern to producers of small fruits and to justify further investigation for it’s control, especially chemical control for a possible change in status. Therefore, the goal of this work was to evaluate, in laboratory, mortality of D. suzukii adults and ovicidal effect when exposed to different insecticides registered for species of the Tephritidae and Agromyzidae families in different cultures. The insecticides deltamethrin, dimethoate, spinosad, fenitrothion, phosmet, malathion, methidathion, and zeta-cypermethrin resulted in mortality to 100 % of the subjects three days after the treatment (DAT). Regarding the effects over eggs, it was  established that the insecticides fenitrothion, malathion, and methidathion deemed 100 % of the eggs not viable, followed by phosmet and diflubenzuron, which also caused elevated reduction in the eclosion of larvae two DAT.
