Heterogeneous distribution of Cardinium in whitefly populations is associated with host nuclear genetic background
In conclusion, our results provide evidence thatCardinium-mediated fitness effects were closely associated with the host genetic background, which provides a fundamental basis for understanding the mechanism underlying the heterogeneous distribution ofCardinium inB. tabaci MED populations across China.

Female ticks (Ixodes scapularis) infected with Borrelia burgdorferi have increased overwintering survival, with implications for tick population growth
We demonstrate that adult ticks (Ixodes scapularis) infected withBorrelia burgdorferi, the bacterium that causes Lyme Disease, have greater overwintering survival than uninfected ticks.Adult ticks were placed in individual microcosms and allowed to overwinter. In the spring we collected the ticks and tested both dead and living ticks forB. burgdorferi DNA. We also performed lab tests to show that we could accurately identifyB. burgdorferi DNA in ticks 10 weeks after their death. The study was repeated over 3 years, and infected ticks were more likely to survive the winter than uninfected ticks in each of the 3 winters in t...

Bombyx mori nucleopolyhedrovirus induces BmFABP1 downregulation to promote viral proliferation
Fatty acid binding proteins (FABPs) are important endogenous cytoprotectants. However, FABP studies have been poorly reported in invertebrates. Our earlier study discovered theBombyx mori fatty acid binding protein 1 (BmFABP1) by coimmunoprecipitation. BmFABP1 can inhibit the replication ofB. mori nucleopolyhedrovirus (BmNPV) when the silkworms are infected with BmNPV. AbstractFatty acid binding proteins (FABPs) play an important role as endogenous cytoprotectants. However, studies on FABPs in invertebrates are scarce. Previously, we discoveredBombyx mori fatty acid binding protein 1 (BmFABP1) through co-immunoprecipitatio...

A secreted salivary effector from Riptortus pedestris impairs soybean defense through modulating phytohormone signaling pathways
This study found that a salivary protein Rp2155 ofRiptortus pedestris was involved in promoting pest infestation, and provided a useful RNA interference target for pest control. Our results also demonstrated evidence to help understand the role of the salivary proteins on the prevention and treatment of staygreen syndrome. AbstractRiptortus pedestris (Fabricius), one of the major piercing-sucking insects in soybeans, causes delayed plant senescence and abnormal pods, known as staygreen syndrome. Recent research has shown that direct feeding of this insect is the major cause of soybean staygreen syndrome. However, it remain...

Identification and characterization of extrachromosomal circular DNA in the silk gland of Bombyx mori
The silk gland cells of silkworm are special cells in which division occurs only at the embryonic stage. Throughout the larval stage, the silk gland cells only replicate DNA in the nucleus without cell division. The extrachromosomal circular DNAs (eccDNAs) have not yet been reported in the silk gland of silkworms. Herein, Zhuet al. have explored the characterization of eccDNAs in the posterior silk gland of silkworms. Motif analysis revealed that dual direct repeats flanking the 5 ′ and 3′ breaking points of eccDNA might support possible models for eccDNA generation. Genomic annotation of the eccDNA found that silk p...

Methyl ‐CpG binding domain (MBD)2/3 specifically recognizes and binds to the genomic mCpG site with a β‐sheet in the MBD to affect embryonic development in Bombyx mori
In this study, we identified 2 isoforms of the MBD2/3 gene inBombyx mori, MBD2/3-S and MBD2/3-L. Binding analysis of MBD2/3-L, MBD2/3-S, and 7 mutant MBD2/3-L proteins deficient inβ1 −β6 orα1 in the MBD showed thatβ2 −β3-turns in theβ-sheet of the MBD are necessary for the formation of the MBD2/3 –mCpG complex; furthermore, other secondary structures, namely,β4 −β6 and anα-helix, play a role in stabilizing theβ-sheet structure to ensure that the MBD is able to bind mCpG. In addition, sequence alignment and binding analyses of different insect MBD2/3s indicated that insect MBD2/3s have an intact and conser...

Research progress toward the influence of mosquito salivary proteins on the transmission of mosquito ‐borne viruses
Mosquito salivary proteins (MSPs) bear multitudinous functions, embracing facilitating blood feeding and affecting the infection of mosquito-borne viruses (MBVs)via directly interplaying with MBVs or tuning the homeostasis of host cells.In vivo, MSPs can modulate host's innate and adaptive immunity, which in turn impacts the native infection at the bite site and the remote dissemination of MBVs. MSP-based MBV transmission-blocking vaccines are neoteric and effective tactics to stifle the MBV transmission. AbstractMosquito-borne viruses (MBVs) are a large class of viruses transmitted mainly through mosquito bites, including...

Cover Caption
The social aphidPseudoregma bambucicola can produce morphologically and behaviorally specialized sterile soldiers and reproductively normal nymphs, and represents a good model system for studying social evolution. The cover photo shows a colony of this species on bamboo, in which several parthenogenetic viviparous mothers are producing offspring. Remarkable reproductive plasticity in parthenogenetic mothers and a novel strategy of regulating caste ratio via maternal reproductive differentiation were found in this social hemipteran (see pages 582-586).

Paper wasps larval formations from the perspective of physics
From a physics perspective, paper wasps arrange larval systems in specific formations to attain mechanical stability for the nest. The closer the distance between the center of mass of the larval system (CML) and the center of mass of the nest (CMN), the lower the moment of force generated by the larval system, resulting in a more stable nest.

Improvement in bioconversion efficiency and reduction of ammonia emission by introduction of fruit fermentation broth in a black soldier fly larvae and kitchen waste conversion system
In this study, we measured the effects of adding fruit fermentation broth (Fer) and commercial lactic acid bacteria fermentation broth (Em) to kitchen waste (KW), as deodorizing auxiliary substances, on the growth performance of black soldier fly larvae (BSFL), the intestinal flora structure of BSFL, the ammonia emission from the KW substrate, and the microbial community structure of the KW substrate. We found that the addition of Fer or Em increased the body weight of BSFL after 6 d of culture, increasing the growth rate by 9.96% and 7.96%, respectively. The addition of Fer not only reduced the pH of the KW substrate but ...
