O objetivo deste trabalho foi avaliar a variabilidade vertical e horizontal do teor de fósforo e potássio do solo de um plantio detaxi-branco (Tachigalivulgaris)com aproximadamente sete anos e meio de idade, em três espaçamentos, localizado em Dom Eliseu, PA. As parcelas amostrais foram dispostas em blocos ao acaso com quatrorepetições, nas quais foram escolhidos,aleatoriamente,16 pontos de coleta do solo em quatroprofundidades. As amostras de solo coletadas foram transportadas para o laboratório de solos da Embrapa Amazônia Oriental, onde foram realizadas as análises químicas. Concluiu-se quenos espaçamentos mais adensados, houve diferença significativa entre as profundidades, para oteor de fósforo e potássio, mostrando-semaior teor na superfície do solo. Porém, em profundidade total apresentou diferença significativa entre os espaçamentos, mais adensado e menos adensado. |

The velvetbean caterpillar (VBC), Anticarsia gemmatalis Hübner, 1818 (Insecta: Lepidoptera: Noctuidae), is one of the most important New World soybean agro-ecosystems pests, occurring from 40° N in the USA to 39° S in Argentina. Information on the migration patterns of the VBC moth may be important for managing the resistance of VBC populations to insecticides or plants carrying the Bacillus thuringiensis insecticide genes, especially since sedentary populations have a higher potential to became resistant than migratory populations. We studied intraspecific variations of geographically distinct VBC populations in order to determine the genetic distance between them and to assess the variability of VBC populations from near the city of Londrina (Paraná (PR) state, Brazil). Samples of the VBC were obtained from sites near the following towns or cities: Marianna and Quincy (Florida, USA); La Virginia (Tucumán province, Argentina); Londrina (PR), Passo Fundo (Rio Grande do Sul, Brazil) and Planaltina (Goiás, Brazil). The VBC samples were used to construct a genetic similarity matrix based on random amplified polymorphic DNA (RAPD) allele frequencies, the cotton leafworm, Alabama argillacea, Hübner 1823 (Insecta: Lepidoptera: Noctuidae), being used as an outgroup. Interestingly, despite the great distance (about 6,500 km) between Planaltina and Quincy some of the specimens from the Quincy population clustered in a group genetically close to the Planaltina populations. Larvae collected on peanuts in Marianna and on soybean in Quincy, 70 km apart, appeared genetically similar. The population from Planaltina was the most heterogeneous (polymorphism = 85.6%; heterozygosity = 0.1505). The Argentinean VBC population was entirely different from the Brazilian populations. The genetic similarities found between individuals from geographically distant populations and effective migration rate values (2.0566 > Nm < 15.2618) indicate that migration occurs.
