Intra- and inters-specific effects of Nilaparvata lugnes (St l) and Sogtella furcifera (Horv th)(Homoptera: Delphacidae) on their population performances on Indica Zhe 852, Japonica XiuShui 11 and Hybrid XY 9308 were studied in the laboratory. Intra-specific crowding did not influence the performance of N. lugens except for emergence rate on Z 852, but adversely affected the nymphal development duration of X. furcifera on Xiushui 11 and XY 9308, and emergence rates, adult longevity and fecundity on Xiushui 11. The inter-specific interactions between the nymphs of N. lugens and S. furcifera provided positive effects for both the species, but more benefits to S. furcifera.The nymphal development duration, emergence rate and fecundity of S. furcifera raised in mixed cultures for all the three varieties were often significantly shorter or higher than those raised in pure cultures, but only the emergence rate and fecundity of N. lugens raised in mixed cultures. on Zhe 852 and XY9308 were higher than those raised in pure culture. Both species suffered little delayed negative intra-specific effects and gained dramatic delayed positive inter-specific effects from another species previously fed on the plants. The nymphal development duration, adult emergence rate, female longevity and fecundity of each species were positively affected when reared on the plants sucked by another species before. The change of distribution pattern of S. furcifera reared on the plants fed by BPH before revealed the positive effects from inter-specific.

Analysis of historical and experimental data collected in Jiaxing, Zhejiang Province, China, indicated the population development pattern there was a typical temperate type with low immigration and high growth rate. Population dynamics was affected by temperature, variety and natural control agents, as well as immigration. Forecasting process was described and prediction could be improved by using multi-regression models incorporating immigration size, percentage f area grown resistant varieties and temperature in mid-September. An ecological approach for improvement of BPH management was proposed, because frequent outbreak in temperate regions was mainly resulted from high growth rate there and inappreciative chemical control might cause resurgence.

Chemosensory proteins (CSP) afford insects the ability to recognize complicated environmental cues and are involved in diverse physiological processes. The planthoppers Laodelphax striatellus and Sogatella furcifera are serious specialist pests of rice throughout eastern Asia. In this study, we identified 21 putative CSP genes (namely LsCSP1–12 and SfCSP1–9) in the two planthoppers L. striatellus and S. furcifera, and profiled their transcript accumulation in different developmental stages and body parts by real-time quantitative PCR (qPCR). All CSPs had the characteristic typical features of the CSP family, with the exception of LsCSP10 and SfCSP2, which lacked the predicted signal peptide sequence. Among these putative CSP genes, only two (LsCSP9 and SfCSP5)weremore highly expressed in the antennae, indicating that they might be involved in olfaction. On the contrary, eleven genes (LsCSP2, 3, 4, 6, 8, 12; SfCSP1, 4, 6, 7, 8) and one gene (SfCSP9) were more highly expressed in the legs and heads (without antennae), respectively. The remainders of the genes were ubiquitously expressed in the heads (without antennae) and the bodies (without the legs and heads). The broad expression patterns in different body parts indicate that the CSPs of these two delphacid species may be involved in diverse functions besides chemosensation. These findings increase the understanding of the chemosensory protein system of Hemiptera species.
