data for life-table analysis. The problem of sampling low populations between outbreaks is a major obstacle to life-table studies, but it is essential to understand this phase to explain the development of outbreaks. The nuclear polyhedrosis virus (NPV) of N. sertifer has been found in most sampled outbreak areas in Swe-den (Olofsson, unpubl.).   Neodiprion sertifer (Geoffroy) has a wide temperature tolerance, experiencing egg mortality below −35°C in northern Finland (Virtanen et al. ) and increasing levels of larval mortality from nucleopolyhedrosis viruses above 25°C in Wisconsin (Mohamed et al. ).

Euproctis latifascia Walker is an important pest attacking old leaves of tea bushes and mother leaves of nursery cuttings in Darjeeling foothills, Terai and Northeast India. Laboratory experiments were designed to assess the effect of an artificial diet and a natural diet, i.e. tea leaves, Camellia sinensis, on life history traits like development time, survival and fecundity of E. latifascia. The University of Florida’s Institute of Food and Agricultural Sciences (UF/IFAS) is a federal-state-county partnership dedicated to developing knowledge in agriculture, human and natural resources, and the life sciences, and enhancing and sustaining the quality of human life by making that information accessible.

Two sawfly species that feed on white fir were studied in Modoc County, California: Neodiprion near deleoni Ross and N. abietis complex. Neodiprion near deleoni comprised 91 percent of the field Neodiprion populations and spun opaque brown cocoons in the litter or soil. Neodiprion abietis accounted for 9 percent of the field population and spun translucent cocoons that appear green and .

The genome of the Neodiprion sertifer nucleopolyhedrovirus (NeseNPV), which infects the European pine sawfly, N. sertifer (Hymenoptera: Diprionidae), was sequenced and analyzed. The genome bp in size. The C+G content of 34% was lower than that of the majority of baculoviruses.

Diprion pini (L.) and Neodiprion sertifer (Geoffroy) (Hymenoptera: Diprionidae) are two of the most important sawfly pests in Italy, and both species are parasitized by the hymenopteran parasitoid.

Changes in needle nitrogen and resin acid concentrations in young Scots pine trees fertilized with ammonium nitrate were followed over 3 years. Sawfly larvae (Neodiprion sertifer) were reared on fertilized and control trees the year after fertilization.

Both nitrogen and resin acid concentrations increased in fertilized trees. The fact that resin acid concentrations increased contradicts. Nakamura, H. () Ecological studies on the Europian pine sawfly,Neodiprion sertifer (Geoffroy) (Hymenoptera: Diprionidae).II.

This variation is thought to play a central role in Neodiprion diversification, but speciation hypotheses remain untested due to a lack of a robust phylogenetic estimate.

Sawflies are important pests of various plant species. Diprion pini (L.) and Neodiprion sertifer (Geoffroy) (Hymenoptera: Diprionidae) are two of the most important sawfly pests in Italy, and both species are parasitized by the hymenopteran parasitoid Dahlbominus fuscipennis (Zetterstedt).

Bacterial endosymbionts are currently studied for their high potential in strategies of biocontrol in a. In Europe and to a lesser extent in North America, the European pine sawfly, Neodiprion sertifer, is a pest of various growth stages of pines.

Bird [ 6 ] imported an NPV from Sweden to Canada and used it to effectively control infestation in the eastern part of the country.

Although adults from each of four study areas in California showed no morphological differences and were identified as belonging to the Neodiprion fulviceps complex, a number of biological differences in different stages of development indicate that there are three distinct populations of one species or subspecies of a species in the, N.

It is particularly serious in.The effect of defoliation by Neodiprion sertifer on the growth of Pinus sylvestris in Romagna, Italy, was studied in Both tree height and radial growth were adversely affected by defoliation.

When completely defoliated, the growth of the stem declined by 76%. Stem growth was also correlated with tree height. Initial stem diameter had no effect on subsequent yearly growth.Get this from a library!
