Influence of different tropical fruits on biological and behavioral aspects of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera, Tephritidae). Studies on Ceratitis capitata, a world fruit pest, can aid the implementation of control programs by determining the plants with higher vulnerability to attacks and plants able to sustain their population in areas of fly distribution. The objective of the present study was to evaluate the influence of eight tropical fruits on the following biological and behavioral parameters of C. capitata: emergence percentage, life cycle duration, adult size, egg production, longevity, fecundity, egg viability, and oviposition acceptance. The fruits tested were: acerola (Malpighia glabra L.), cashew (Anacardium...

Alternation of host plants as a survival mechanism of leafhoppers Dilobopterus costalimai and Oncometopia facialis (Hemiptera: Cicadellidae), vectors of the Citrus Variegated Chlorosis (CVC)
Provedor de dados: 63
Autores: Milanez,José Maria; Parra,José Roberto Postali; Magri,Denise Cristina.
Dilobopterus costalimai (Young) and Oncometopia facialis (Signoret) are two of the most important species of citrus leafhoppers, vectors of bacterium Xylella fastidiosa which causes the Citrus Variegated Chlorosis (CVC) disease. To develop a rearing technique for these species under laboratory conditions, the egg laying preference and nymph development were studied in different breeding systems: Rangpur lime (Citrus limonia) and "falso boldo" (Vernonia condensata) as host plants. Trials were set up in a randomized block design with three treatments (n=8). Females of D. costalimai had particular preference for ovipositing on Rangpur lime leaves while O. facialis females placed a higher number of eggs on "falso boldo", but it did not differ statistically...

Suboptimal nutrition and feeding behavior of hemipterans on less preferred plant food sources
Provedor de dados: 44
Autores: Panizzi,Antônio R.
Phytophagous hemipterans (heteropterans) are, in general, polyphagous, feeding on a wide array of plants. Among these, less preferred plant food sources are also explored as food and/or shelter. To illustrate this, I will discuss the feeding behavior of the southern green stink bug, Nezara viridula (L.) (Pentatomidae) on less preferred plants in Northern Paraná state. This bug feeds on several uncultivated-wild, and on cultivated plants, which are less preferred, changing its feeding behavior, from a typical seed/fruit sucking habit, to leaf/stem feeding, with consequences for its nymphal and adult performance. Other seed suckers, such as Euschistus heros (F.) and Dichelops melacanthus (Dallas) (Pentatomidae) and Neomegalotomus parvus Westwood (Alydidae),...

Autores: Suzana,Crislaine Sartori; Rosa,Cálvin Felipe; Alves,Fabriele da Luz; Salvadori,José Roberto.
ABSTRACT:  A deep insight into the population dynamics of a pest can be achieved by being acquainted with its nutritional ecology, which further assists in understanding the damage potential and decisions to control mainly in diversified production systems such as those in Brazil. The present r research aimed to evaluate the effect of dietary regimens, comprising combinations of acessible organs of soybean plants, at different stages of development, consumption, and utilization of food by the 4th, 5th, and 6thlarvae instar of Helicoverpa armigera (Hübner) (Lep.: Noctuidae). For this purpose, the vegetative and reproductive organs of soybean were brought together in three feeding regimes, followed by making it available to caterpillars. After evaluations,...
