The results demonstrated that the 5th instar nymphs of L. riparia showed strong predation capacity to the eggs, larvae and even the flightless adults of S. frugiperda. When L. riparia preyed on S. frugiperda, L. riparia did not eat up S. frugiperda completely; instead, L. riparia bited S. frugiperda until the preys could not move and then transferred to attack other preys. The predatory functional response of the 5th instar nymphs of L. riparia to 6th instar larvae S. frugiperda fitted well with Holling II model, with average preying number of 2.85 per day. L. riparia can be used as a potential local natural enemy to control the invasive pest S. frugiperda in the future.

According to the pheromone gland transcriptome data, the AipsCSP2 gene was cloned and analyzed by bioinformatics and phylogenetic analysis. The expression level of the gene in different tissues of male and female adult was determined by qPCR. The recombinant protein was expressed and purified with prokaryotic expression system. Finally, the binding ability of this protein to the sex pheromone components of A. ipsilon and other Lepidoptera insects, as well as the volatiles of the main host plants were determined by fluorescence competitive binding assay. Results showed that the open reading frame (ORF) of AipsCSP2 gene was 360 bp and it encoded 119 amino acids. It has four conserved cysteines in the amino acid sequence and is a typical chemosensory protein. The tissue expression patterns showed that it was specifically high expressed in the female adult pheromone gland and male adult accessory gland, low expressed in other tissues. Fluorescent competitive binding assay results showed that AipsCSP2 has a very strong binding ability to cis-11-hexadecylaldehyde, the precursor of A. ipsilon sex pheromone cis-11-hexadecylacetate, with Ki of 1.48 μmol/L. It also has a strong binding ability to alcoholic and aldehydic sex pheromone of other Lepidoptera insects, such as tetradecanol, cis-9-hexadecaldehyde and cis-7-hexadecaldehyde, with Ki of 1.10 μmol/L, 0.63 μmol/L and 1.51 μmol/L. It has a moderate ability to the sex pheromone components of A. ipsilon cis-7-dodecanoacetate and cis-8-dodecanoacetate. The binding ability to the volatiles of the main host plants of A. ipsilon was weak or not. It is suggested that AipsCSP2 may be involved in the synthesis and recognition of sex pheromone in A. ipsilon, and play an important role in reproductive activities.

Although EBPM techniques have been successfully applied in the field level to control many agricultural pests with sustainable and green characteristics, the systematic strategies of EBPM from field level to regional scale still lack. In order to solve regional EBPM of agricultural pests, we summarized the landscape characteristics of pest population, including regional distribution, heterogeneity, diffusivity, outbreak, and synergy. Then, we clarified the systematic strategies of regional EBPM, which included preventive management, targeted management and post-outbreak control. A regional strategy of prevention, management, and control would be effective to suppress outbreak of agricultural pests. Finally, we summarized the advantage of regional EBPM in the future, which emphasize safety, efficiency, precision and sustainability of insect pest management. Therefore, the regional EBPM is an inevitable choice to ensure the ecological security and agricultural food production in the future.

Lefavirales consists of three families including the Baculoviridae. Baculoviridae is divided into four genera:Alphabaculovirus, Betabaculovirus, Deltabacuulovirus, and Gammabaculovirus. Total 85 major baculovirus species are included in the list. According to the ICTV website, the baculovirus species name consists of the host insect species name and virus characteristic words (nucleopolyhedrovirus or granulovirus), the initial letter of the host genus is uppercase, the other letters are lowercase. The virus species name (when used for system classification) is written in italics, but in other cases, the virus name including the name of a host species should never be italicized. The abbreviation of baculovirus name consists of the first two letters of the host genus and those of the species name followed by the abbreviation of nucleopolyhedrovirus (NPV) or granulovirus (GV), while the 16 traditional baculovirus abbreviations still use the acronyms of host genus and species name followed by NPV or GV.

Effects of landscape habitats on birds and insect natural enemies and maize aphid populations were analyzed in five different habitats. The results showed that the populations of ladybird (Propylaea Japonica) and lacewing (Chrysopa perla) were the largest in farmland landscape with 20% of non-maize fields, while ladybird (Harmonia axyridis) was the largest in farmland landscape with 30% of non-maize habitats. The farmland landscape with 15%, 20%, 30% and 40% non-maize habitat were conducive to the conservation of Chinese bulbul (Pycnonotus sinensis) and turtle dove (Streptopelia turtur), sparrows (Passer montanus), magpie (Pica pica) and house swallow (Hirundo rustica), and hoopoe (Upupa epops), respectively. The cumulative quantity of maize aphid was the lowest in the farmland landscape with 30% of non-maize habitats. The results of exclusion of birds and natural enemies showed that they had significant control on maize aphid. The farmland landscape with 20% non-maize habitat can conserve more natural enemies and reduce maize aphid, and improve the biological control service of farmland landscape on maize pests.

As important biocontrol agents, parasitoids usually provide efficient natural control of insect pests. This study aimed to clarify the occurrence of C. viridis as well as the biological characteristics of its egg parasitoids in Xinjiang, which may provide basic information that can benefit the conservation of native parasitic natural enemies and the biological control of C. viridis via mass-rearing and release of parasitoids. During 2014-2015, the life history of C. viridis was investigated in Manas National Wetland Park. C. viridis had two generations annually and overwintered as eggs in this region. Two egg parasitoid species of C. viridis were identified, Paracentrobia exilimaculata Hu & Lin was a worldwide first report parasitizing C. viridis and Gonatocerus longicornis Nees was a first report in China. The natural parasitism rate by the dominant egg parasitoid G. longicornis peaked in early September (74.96%) and averaged 49.70%. The eclosion rate and the sex ratio increased and then decreased with the increase of temperature from 15℃ to 40℃. The immature stage (from egg to adult emergence) took 9 to 16 days, averaging 14. 25 days. The lifespan of adult wasps fed with 15% honey solution ranged from 6 to12 days (Female:9.38 d; Male:8.50 d), and the females lived 1-2 days longer than the males. The optimal rearing conditions for G. longicornis were 30℃, 45% RH and photoperiod 14L:10D, and these conditions favored its parasitization of C. viridis. The parasitoid has high potential for the biological control against C. viridis. Reference | Related Articles | Metrics | Comments（0）
