Objective: This study examined the contribution of age, type of human papillomavirus (HPV), attachment, sexual satisfaction, and spirituality in dyadic adjustment in women with HPV from diagnosis to one year later. Method: This is a longitudinal study with three assessment moments: (T1) at the diagnosis appointment, (T2) six months after, and (T3) 12 months after the diagnosis. Participants answered a sociodemographic questionnaire as well as several other measures: HPV Knowledge Questionnaire (HPVQ), Papanicolaou Exam Knowledge Questionnaire (PEK-Q), Hospital Anxiety and Depression Scale (HADS), Courtauld Emotional Control Scale (CECS), Index of Sexual Satisfaction (ISS), Experiences in Close Relationship Scale-Short Form (ECR-S), Spiritual and Religious Attitudes in Dealing With Illness (SpREUK), and the Revised Dyadic Adjustment Scale (RDAS). Results: Age showed a positive impact on sexual dissatisfaction at T2. Sexual dissatisfaction at T1 predicted sexual dissatisfaction at T2 and dyadic adjustment at T3. Spirituality and insecure attachment at T1 negatively predicted insecure attachment at T2, and the latter predicted dyadic adjustment at T3. Conclusions: The results corroborate the need to assess the dyad when women are diagnosed with HPV. Only then it will be possible to design differentiated intervention programs that take into consideration women's age, attachment style, and sexual satisfaction. Interventions should also include women's partners to promote dyadic adjustment in this population.

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 species and were evaluated at 7, 14, 28, 35, 42, and 49 days after the infestations. Mathematical models were used to fit the population dynamics of two aphid species. There were good fits for aphid dynamics by mathematical model over time. The highest population peak of both species A. gossypii and A. craccivora was found in the sole crops, and the lowest population peak was found in crop system t2. These results are important for integrated management programs of aphids in cotton and cowpea. Made available in DSpace on 2018-11-25T23:32:45Z (GMT).

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 handling time. Podisus nigrispinus females showed functional response types II and III by preying on larvae and pupae, respectively. The attack rate and handling time did not differ between the 12 and 24 h exposure times. Predation rate was higher at higher larval and pupal densities; predation was highest at a density of 30 prey items per female, and it was similar at 18 and 24 prey per predator. Understanding the interaction of predators and their food resources helps to optimize biological control strategies. It also helps the decisionmaking and the improvement of release techniques of P. nigrispinus in the field.

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 ladybugs. Significant associations among both apterous and alate H. foeniculi and C. sanguinea were observed in both the fennel and fennel-cotton intercropping systems. The similarity analysis showed that the presence of aphids and ladybugs in the same system is significantly dependent on the type of crop. A substantial amount of evidence indicates that the presence of the ladybug C. sanguinea, is associated with apterous or alate A. gossypii and H. foeniculi in fennel-cotton intercropping system. We recommend that future research vising integrated aphid management taking into account these associations for take decisions. Made available in DSpace on 2016-03-16T08:02:48Z (GMT).

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 of fennel seeds from umbels in the green stage in treated plots (0.19 mg) washigher (21%) than in the non-treated plots (0.15 mg). There was no significant difference in the essential oilextracted from biomass between two cropping systems for both treated and non-treated plots. However,the amount of essential oil extracted from fennel biomass in treated plots was higher in fennel plots thanin fennel in non-treated plots. The average of the essential oil of 1000 fennel seeds from fennel-cotton intercropping system (0.17 ml) was higher (18%) than in the fennel cropping system (0.14 mg). The aphid attack reduced 29% of fennel seed weight. On the other hand, the average amount of essential oil extractedof the non-attacked seeds was two folds higher than of the attacked seeds. Therefore, our results showed that the effects of H. foeniculi on these yield components were smaller in the plots with fennel-cotton intercropping than in fennel plots. We suggest that seed composition responses to H. foeniculi injury should be an important consideration when conducting research to develop IPM systems for this fennel pest.
