Última Insecticide resistance in Argentine populations of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) Neotropical Entomology Lietti,Marcela M.M.; Botto,Eduardo; Alzogaray,Raúl A.. The tomato leafminer, Tuta absoluta (Meyrick), is one of the key pests of tomato in Argentina. Since its dispersal in the 1970s, chemical control has been the main method of controlling it. However, reduced efficacy of some of the recommended insecticides has been observed since the 1980s. The aim of this work was to study the toxicity of three insecticides widely used in chemical control of T. absoluta (abamectin, deltamethrin and methamidophos) on larvae from a laboratory susceptible population (CASTELAR) and two greenhouse populations (ROSARIO and BELLA VISTA). Insecticides were dissolved in acetone and topically applied to the mid-dorsal abdominal region of two-day old 4th instar larvae. LD50 values were estimated and the Resistance Ratio (RR) for each...

Main Factors affecting brown planthopper (BPH) outbreaks in the Central region from past up to now are cultivations of susceptible rice varieties and misused insecticide application. The aim of this research was to prove the misused of insecticide application in the hot spot area causing BPH severe outbreak. One hundred to one hundred fifty farmers from six provinces: Nakhon Nayok, Suphan Buri, Ang Thong, Chai Nat, Phitsanulok and Nonthaburi were interviewed during August to November 2010. The result found 56.5 to 100 percent of farmer sprayed insecticide for two to six times/seasons. Most farmers applied insecticide, especially Abamectin as cocktails mixed with two to six types of fungicides and/or herbicides. Most farmers were sprayed insecticide when...

Ano: 2013 URL: http://anchan.lib.ku.ac.th/agnet/handle/001/5679 Seed treatment affects Meloidogyne incognita penetration, colonization and reproduction on cotton Ciência Rural Bessi,Rosana; Sujimoto,Fernando Ribeiro; Inomoto,Mário Massayuki. The effect of abamectin, applied as seed treatment, on Meloidogyne incognita penetration, colonization, and reproduction on cotton was evaluated in two greenhouse experiments. Second stage juveniles (J2) penetration was evaluated 3, 9 and 15 days after germination (dag), whereas the nematode colonization was evaluated 27dag, by counting the total number of galls and egg masses per root system. Eggs and J2 were extracted from the roots to assess the nematode reproduction at 50 and 100dag. The seed treatment caused a decrease in J2 penetration in the roots, resulting in lower colonization and reproduction of M. incognita. These findings are discussed considering the environmental aspects of abamectin in the soil and the current practices for the crop...
