Assessment of the attack of Hyadaphis foeniculi (Passerini) (Hemiptera: Aphididae) on biomass, seed and oil in fennel intercroped with cotton with colored fibers. Repositório Alice
RAMALHO, F. de S.; MALAQUIAS, J. B.; SANTOS, B. D. B. DOS; FERNANDES, F. S.; ZANUNCIO, J. C..
The fennel aphids, Hyadaphis foeniculi (Passerini) (Hemiptera: Aphididae) attack umbels and may thus,cause to failure of fruit setting and also attack during the phase of seed development. Our research investigated the severity of biomass, seed and essential oil damages related to infestation by the fennel aphid, H. foeniculi in fennel (Foeniculum vulgare Miller) plots and plots of fennel intercropped with cotton with colored fibers. A randomized complete block design was used with four treatments: (1) two rows offennel: three rows of cotton (2F: 3C) (non-treated plot), (2) two rows of fennel: three rows of cotton (2F:3C) (treated plot), (3) fennel (F) (non-treated plot), and (4) fennel (F) (treated-plot), with four replications.The average of the weight...

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...

FERNANDES, F. S.; RAMALHO, F. de S.; MALAQUIAS, J. B.; GODOY, W. A. C.; SANTOS, B. D. B..
Aphids cause significant damage to crop plants. Studies regarding predator-prey relationships in fennel (Foeniculum vulgare Mill.) and cotton (Gossypium hirsutum L.) crops are important for understanding essential ecological interactions in the context of intercropping and for establishing pest management programs for aphids. This study evaluated the association among Hyadaphis foeniculi (Passerini) (Hemiptera: Aphididae), Aphis gossypii Glover (Hemiptera: Aphididae) and Cycloneda sanguinea (L.) (Coleoptera: Coccinellidae) in cotton with coloured fibres, fennel and cotton intercropped with fennel. Association analysis was used to investigate whether the presence or absence of prey and predator species can indicate possible interactions between aphids and...

MALAQUIAS, J. B.; GODOY, W. A. C.; GARCIA, A. G.; RAMALHO, F. de S.; OMOTO, C..
High dispersal of Lepidoptera larvae between non-Bt and Bt cotton plants can favour the evolution of insect resistance; however, information on host acceptance of neonates in tropical transgenic crops is scarce. Therefore, the purposes of this study were as follows: (i) to investigate the feeding behaviour of susceptible and Cry1F-resistant strains of Spodoptera frugiperda (J.E. Smith) on Bt and non-Bt cotton (Gossypium hirsutum L.) varieties and (ii) to understand the possible effects of cotton field contamination on the dispersal and infestation capacity of S. frugiperda larvae by using an individualbased model. The main results of this paper are as follows: (1) the highest post-feeding larval dispersal of the Cry1F-resistant strain occurred at an...

Population dynamics of Aphis gossypii Glover and Aphis craccivora Koch (Hemiptera: Heteroptera: Aphididae) in sole and intercropping systems of cotton and cowpea. Repositório Alice
FERNANDES, F. S.; GODOY, W. A. C.; RAMALHO, F. de S.; GARCIA A. G.; SANTOS, B. D. B. dos; MALAQUIAS, J. B..
Population dynamics of aphids have been studied in sole and intercropping systems. These studies have required the use of more precise analytical tools in order to better understand patterns in quantitative data. Mathematical models are among the most important tools to explain the dynamics of insect populations. This study investigated the population dynamics of aphids Aphis gossypii and Aphis craccivora over time, using mathematical models composed of a set of differential equations as a helpful analytical tool to understand the population dynamics of aphids in arrangements of cotton and cowpea. The treatments were sole cotton, sole cowpea, and three arrangements of cotton intercropped with cowpea (t1, t2 and t3). The plants were infested with two aphid...

Sulphur sources on the management of Scaptocoris castanea (Hemiptera: Cydnidae) on cotton. Repositório Alice
NASCIMENTO, V. L. do; MIRANDA, J. E.; MALAQUIAS, J. B.; CARVALHO, M. da C. S.; LINS, L. C. P.; PANIAGO, J..
Soil fertility with sulphur sources is an important tool that can be used in the management of pests. Sulphur can induce tolerance or even cause mortality to insect pests. This study evaluated the application of sulphur sources on the population dynamics of Scaptocoris castanea (Hemiptera: Cydnidae) and its effects on cotton plants. The experiment had a factorial design consisting of a combination of four concentrations of calcium sulfate (CaSO4) and four concentrations of ammonium sulphate [(NH4)2SO4]. There was no correlation between soil humidity (%) and insect infestation (%) (nymphs + adults), except for the treatment without calcium sulfate (0 kg/ha) along with 208 kg/ha of ammonium sulfate. There was a significant difference between average and...

RAMALHO, F. de S.; MALAQUIAS, J. B.; LIRA, A. C. S.; OLIVEIRA, F. Q.; ZANUNCIO, J. C.; FERNANDES, F. S..
Hyadaphis foeniculi (Passerini) (Hemiptera: Aphididae) is a cosmopolitan species and the main pest of fennel in northeastern Brazil. Understanding the relationship between temperature variations and the population growth rates of H. foeniculi is essential to predict the population dynamics of this aphid in the fennel crop. The aim of this study was to measure the effect of constant temperature on the adult prereproductive period and the life table fertility parameters (infinitesimal increase ratio (rm), gross reproduction rate (GRR), net reproduction rate (R0), finite increase ratio (?), generation time (GT), the time required for the population to double in the number of individuals (DT), and the reproduction value (RVx)) of the fennel pest H. foeniculi....
