The effect of different constant temperatures on the emergence of second -stage juveniles of H. schachtii and H. betae was investigated using six incubators set at 5, 10, 15, 20, 25 and 30 degrees C for a period of 6 weeks. In a second experiment, the effect of increased and standard temperature regimes on the emergence of second -stage juveniles of H. schachtii and H. betae was investigated in climate chambers for 12 weeks. The highest cumulative hatching rates for H. schachtii were observed at temperatures between 15 and 30 degrees C and for H. be tae between 20 and 30 degrees C, suggesting that this can be considered as the optimal temperature range for hatch. The emergence of juveniles of both beet cyst nematode species started at 5 degrees C, but cumulative hatch percentages were less than 1%.

In addition to studying natural infestations, we established artificial infestations within cages to assess the impact of different weevil densities on yield parameters and determinants of the nitrogen balance. Densities of 0.2 adult S. lineatus per plant (20 individuals per m 2) reduced the number of seeds and pods per plant by 18% and 15%, respectively: seeds per pod and thousand-seed weight remained unaffected. A three-fold or five-fold increase in weevil abundance (13-40 or 20 to 100 individuals per m(2)) did not result in an additional reduction in yield. Moreover, the higher weevil abundance did not adversely affect the N-harvest index or soil nitrogen content. We suspect that the impact of adult S. lineatus oil yield and nitrogen parameters is limited by the density-dependent mortality of the larvae. Survival of larvae in turn depends on the nodulation of the plants, which is largely regulated by the supply of water. The assumption that organic cropping systems are at specific risk from the pea leaf weevil was confirmed by increasing population densities during the study period. However, yield losses were independent of adult attack within a wide range of weevil abundance, which indicates the complexity of assessing larval damage based oil adult infestation level. An enhanced intraspecific competition among larvae may account for the absence of linear relationships, considering that especially young instars failed to establish in root nodules at higher densities. We found that adult densities of 0.2 individuals per plant and subsequent larval densities of 7 individuals per plant resulted in destruction of 37% of the root nodules on primary roots, which was much below destruction values reported in other studies. In conclusion, we recommend an early monitoring of weevils and early initiation of control strategies because yield losses were caused by even low weevil densities. Finally, the tolerance of P. sativum to S. lineatus was influenced by the yield level, i.e., tolerance to S. lineatus decreased as yield increased. (C) 2009 Elsevier Ltd.

(DBM) strain to snowpea (Pisum sativum L.) raised the question whether a specialist parasitoid Diadegma semiclausum (DS) could be conditioned to locate and parasitize its host on the new host plant. In a specialist parasitoid a behavioural change towards a plant outside the normal host plant range of its host due to developmental experience is not expected. The responsive behaviour, parasitism rates and fitness of three subsequent DS generations were investigated on the snowpea-strain of DBM. After three generations of DS on the pea 62.5% of females chose an DBM-infested pea plant over DBM infested cabbage. Only 16.4% of cabbage-reared DS was attracted to infested pea. Rearing of the parasitoid in host larvae on peas significantly increased the number of larvae parasitized on this host plant in the first generation; however, there was no further increase in generations 2 and 3. Larval mortality was similar for all parasitoid/DBM combinations on both host plants, but significantly higher mortality occurred in parasitoid pupae from peas. Development time of the parasitoid was slightly prolonged on the pea strain of DBM. The number of females produced by parasitoids reared on the pea strain of DBM was significantly reduced as compared to D. semiclausum reared on the cabbage strain on both host strains. Results show that DS has the potential to change its responsive behaviour in order to locate its host on a new host plant. According to the current view, a specialist parasitoid is not expected to change its reaction to a plant outside the normal host plant range of its host. Within 3 generations, responsive behaviour towards snowpea could be increased.

We therefore aimed at investigating whether and how blastospore (BS) formation can be shifted to resilient submerged conidiospores (SCS) by introducing osmotic stress in different growth phases. When 50 g/L NaCl was added after 48 h to a culture of B. bassiana a yield of 1.4 +/- 0.1 x 10(10) SCS/g sucrose in shake flasks and 1.8 +/- 0.1 x 10(10) SCS/g sucrose in a stirred tank reactor were obtained. In a bioreactor, 24 h after the addition of NaCl, the formation of BS slowed down, the respiratory quotient decreased and a shift from BS to SCS set in. Following these steps, different formulation strategies, namely encapsulation, film coating and liquid formulation were evaluated. B. bassiana grew out of beads as well as on commercial fungicide-coated seeds. Due to the complete suppression of fungal growth on non-sterile soil, the most suitable option was a foliar application. A liquid formulation consisting of 0.1% Triton X-114, 1% molasses, 1% titanium dioxide and 10(6) spores/mL was applied on leaf tips.
