Comparative biology of Cycloneda sanguinea (Linnaeus, 1763) and Hippodamia convergens Guérin-Méneville, 1842 (Coleoptera, Coccinellidae) focusing on the control of Cinara spp. (Hemiptera, Aphididae) Rev. Bras. entomol.
Cardoso,Josiane Teresinha; Lázzar,Sonia Maria Noemberg.
The giant conifer aphids Cinara pinivora (Wilson, 1919) and Cinara atlantica (Wilson, 1919) (Hemiptera, Aphididae) have been observed attacking Pinus spp. in Southern and Southeastern Brazil. The coccinellids, on the other hand, were found feeding on these aphids in the field, which can be regarded as potential biological control agents. The biological cycle and mortality rate of larvae of Cycloneda sanguinea (Linnaeus, 1763) and Hippodamia convergens Guérin-Méneville, 1842 (Coleoptera, Coccinellidae) were evaluated using twenty larvae of each predator species fed with nymphs of Cinara. The vials with the insects were kept under 15 ºC, 20 ºC and 25 ºC, with 12h photophase and 70 ± 10% relative humidity. The consumption was evaluated every 24 hours and the...

Consumption of Cinara spp. (Hemiptera, Aphididae) by Cycloneda sanguinea (Linnaeus, 1763) and Hippodamia convergens Guérin-Méneville, 1842 (Coleoptera, Coccinellidae) Rev. Bras. entomol.
Cardoso,Josiane Teresinha; Lázzari,Sonia Maria Noemberg.
Adults and larvae of coccinellids were observed feeding on populations of the giant conifer aphids Cinara spp. on Pinus spp., in Southern Brazil. The objective of this research is to evaluate the consumption capacity of Cycloneda sanguinea (Linnaeus, 1763) and Hippodamia convergens Guérin-Méneville, 1842 (Coleoptera, Coccinellidae) on these aphid species, in order to obtain information for biological control programs. Ten larvae of each predator species were fed with aphids of small size (nymphs of 1st and 2nd instars), and 10 with aphids of medium size (nymphs of 3rd and 4th instars), maintained under 15ºC, 20ºC and 25ºC, 12 h photophase and 70 ± 10% relative humidity. The aphids were counted every 24 hours, replacing those that were consumed. The total...

Ocorrência e flutuação populacional de Chrysopidae (Neuroptera) em áreas de plantio de Pinus taeda (L.) (Pinaceae) no sul do Paraná Rev. Bras. entomol.

The lacewings are very voracious predators of aphids. The objective of this research was to evaluate the occurrence of adult chrysopids in areas of Pinus reforestation where the giant conifer aphid Cinara spp. (Hemiptera: Aphididae) is causing severe damages. A total of 47 specimens were collected during one year and identified as: Chrysoperla externa (Hagen, 1861), Leucochrysa (Nodita) intermedia (Scheneir, 1851) and Leucochrysa (Nodita) vieirana (Navás, 1913). The captures in the area where the plants were one year old represented about 75% of the adults probably due to the high Cinara infestation on the trees in this area. The chrysopids were recorded mostly during the summer, possibly influenced by temperature.

Development and consumption capacity of Chrysoperla externa (Hagen) (Neuroptera, Chrysopidae) fed with Cinara spp. (Hemiptera, Aphididae) under three temperatures Zoologia
Cardoso,Josiane T.; Lazzari,Sonia M. N..
The giant conifer aphids Cinara pinivora (Wilson, 1919) and Cinara atlantica (Wilson, 1919) (Hemiptera: Aphididae) are pests on Pinus spp. (Pinaceae) in the South and Southeast regions of Brazil. Larvae of Chrysoperla externa (Hagen, 1861) (Neuroptera, Chrysopidae) were observed feeding voraciously on these aphid colonies. In order to evaluate their potential as biological control agents, some biological parameters and their consumption capacity were studied in laboratory. Ten larvae were isolated in plastic vials and fed with aphids of small size (nymphs of 1st and 2nd instars) and 10 with aphids of medium size (nymphs of 3rd and 4th instars), maintained at 15ºC, 20ºC and 25ºC, under 12:12 h photoperiod and 70 ± 10% RH, and observed daily. The egg...

Occurrence of Cinara spp. (Hemiptera, Aphididae) on Pinus spp. (Pinaceae), in the county of Lages-SC, Brazil Rev. Bras. entomol.
Lázzari,Fernanda N.; Trentini,Rosita F. R.; Carvalho,Regina C. Z. de.
A population survey of the giant conifer aphid Cinara spp. was carried out in two areas of Pinus elliottii using yellow pan traps, during two years, from July 1997 to June 1999. During the collection period, the predominant species was Cinara pinivora (Wilson, 1919), representing 99% of the collected species. A few specimens of Cinara maritimae (Dufour, 1833) and only one winged female of Cinara fresai Blanchard, 1939 were collected. The population of C. pinivora was statistically higher in the area with 4.5 year-old trees than in the 1.5 year-old ones. The highest population peaks were registered in July 1997 and in August 1998. An unexpected high number of winged parthenogenetic females was collected in December 1998. C. fresai Blanchard, 1939 is...
