How predation by Podisus nigrispinus is influenced by development stage and density of its prey alabama argillacea. Repositório Alice
SANTOS, B. D. B DOS.; RAMALHO, F. de S.; MALAQUIAS, J. B.; LIRA, A. C. S.; PACHÚ, J. K. S.; FERNANDES, F. S.; ZANUNCIO, J. C..
The functional response of a predator to the density of its prey is affected by several factors, including the prey?s developmental stage. This study evaluated the functional response of Podisus nigrispinus (Dallas) (Hemiptera: Heteroptera: Pentatomidae) females to fourth instars and pupae of Alabama argillacea (H?ubner) (Lepidoptera: Noctuidae), an important pest of cotton (Gossypium hirsutum L., Malvaceae) in Brazil. The prey were exposed to the predator for 12 and 24 h, and in densities of 1, 6, 12, 18, 24, and 30 items per predator female. The predation data were subjected to polynomial regression logistic analysis to determine the type of functional response. Holling and Rogers? equations were used to estimate parameters such as attack rate and...

Multivariate approach to quantitative analysis of Aphis gossypii Glover (Hemiptera: Aphididae) and their natural enemy populations at different cotton spacings. Repositório Alice
MALAQUIAS, J. B.; RAMALHO, F. de S.; DIAS, C. T. dos S.; BRUGGER, B. P.; LIRA, A. C. S.; WILCKEN, C. F.; PACHÚ, J. K. S.; ZANUNCIO, J. C..
The relationship between pests and natural enemies using multivariate analysis on cotton in different spacing has not been documented yet. Using multivariate approaches is possible to optimize strategies to control Aphis gossypii at different crop spacings because the possibility of a better use of the aphid sampling strategies as well as the conservation and release of its natural enemies. The aims of the study were (i) to characterize the temporal abundance data of aphids and its natural enemies using principal components, (ii) to analyze the degree of correlation between the insects and between groups of variables (pests and natural enemies), (iii) to identify the main natural enemies responsible for regulating A. gossypii populations, and (iv) to...
