RESUMO

Abstract Distribution pattern and relative abundance of the agricultural rodent pests of rain-fed and irrigated areas of district Swat Khyber Pakhtunkhwa, Pakistan were recorded from April 2011 to November 2013 using wire mesh live traps. A total of 350 rodents (269 Rattus rattus and 81 Mus musculus) were captured under 2268 trap nights (trap success: 0.15). Regression of daily captures on cumulative captures revealed an estimate of 350 rodents from all the sampled structures with an average of 21.8 rodents per crop field. House rats (R. rattus; 76.8% of captures) were numerically dominant in almost all types of agricultural fields, and were significantly different from the mice (Mus musculus; 23.1% of captures). Both species were found together in some fields. The sex ratio revealed that males outnumbered the females in both of the reported species.


Resumo O padrão de distribuição e a abundância relativa de pragas de roedores agrícolas nas áreas irrigadas e irrigadas do distrito Swat Khyber Pakhtunkhwa, Paquistão foram registrados de abril de 2011 a novembro de 2013 usando armadilhas vivas de malha de arame. Um total de 350 roedores (269 Rattus rattus e 81 Mus musculus) foram capturados em 2268 noites de armadilha (sucesso da armadilha: 0,15). A regressão das capturas diárias em capturas cumulativas revelou uma estimativa de 350 roedores de todas as estruturas amostradas, com uma média de 21,8 roedores por campo agrícola. Os ratos domésticos (R. rattus; 76,8% das capturas) foram numericamente dominantes em quase todos os tipos de campos agrícolas e foram significativamente diferentes dos camundongos (Mus musculus; 23,1% das capturas). Ambas as espécies foram encontradas juntas em alguns campos. A proporção de sexo revelou que os machos superaram as fêmeas em ambas as espécies relatadas.

RESUMO

Ceratonia siliqua L. exhibited a sigmoid growth pattern with each stage being controlled by specific substances. At least three auxin-like substances were involved during fruit morphogenesis with the main one being at indole-acetic acid Rf. Auxin-like substances were present at highest level during stage II, when fruit showed active growth, but decreased at the arrival of stage III. The inhibiting substance I1, at abscissic acid Rf, was present at the highest level at this stage. However, I2, detected towards the last stages of development, was not present at a significant level. The results obtained have been discussed in detail.
