Variability in resistance of species and genotypes of Eucalyptus to the pest is widely reported but without consideration of the influence of silviculture on the severity of galling. We assessed the variability of gall expression by 29 genotypes of E. camaldulensis by L. invasa in common nursery experiments and in 5 common garden arboreta planted in diverse climatic zones and soil types around Kenya. We quantified variation in growth and the concentrations of defensive chemical compounds (namely polyphenolic compounds) to assess possible genotype × environment interactions which we also relate to the climate of the parent seed trees in Australia. Generally, genotypes endemic to low latitude regions of Australia were more resistant to the pest while the concentration of quinic acid derivatives (QUIN) exhibited an interaction with arboretum location in Kenya. The concentration of QUIN in potted plants did not vary significantly with nitrogen supplementation. However, growth rates and total polyphenolic concentrations varied with arboretum location. Since QUIN, which have been previously shown to confer resistance against L. invasa, did not vary in different arboreta, resistant subspecies and genotypes of E. camaldulensis can be deployed in novel habitats and will not be galled. Our findings support the critical need to plant stock of known genotype(s) rather than planting stock grown from locally collected seed. This will require the establishment of eucalypt seed orchards if clonal production of planting stock is not possible.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"1-10"},"PeriodicalIF":1.6,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147269783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, Tr. chilonis (the best trichogrammatid species in the laboratory) was studied inside cages (1 m × 1 m) under maize-field conditions. Egg-to-adult periods (days) were recorded among different species, with Te. remus having the longest (10.00 ± 0.89 days) and Tr. bactrae the shortest (7.80 ± 0.66 days) periods. Furthermore, Te. remus exhibited the greatest adult longevity (days) for both males and females, with and without food. Lifespan parasitism under laboratory conditions was the highest for Te. remus (73.60 ± 7.23 eggs), followed by Tr. chilonis (45.40 ± 2.56 eggs) and Tr. pretiosum (42.00 ± 3.70 eggs).

The net reproductive rate (R0), average generation time (T), and intrinsic rate of increase (rm) differed markedly between Hap3 and Hap17 across C. annuum varieties. Feeding on 'LZ' resulted in a significantly higher R0 value (26.49) for Hap3 relative to other varieties. The T (7.60 days) and rm (0.27) values for Hap3 on 'SE' were superior to those observed on other C. annuum varieties. These findings indicate that 'SE' is the optimal host for Hap3 growth, while 'LZ' best supports Hap17. Both haplotypes exhibited the lowest adaptability to 'LA'. Therefore, the utilisation capacity of A. gossypii populations on C. annuum demonstrates differentiation, and the resistance levels among C. annuum varieties to A. gossypii vary.

BmWARS is localized in the cytoplasm, and is expressed in all tissues of the silkworm, with higher expression in the testis, ovary, silk gland and malpighian tubule.

In addition, overexpression of BmWARS inhibited BmNPV infection and replication extremely significantly, while interference with BmWARS expression promoted BmNPV infection and replication.

Our results showed that the presence of males or females of different species could incur mating interference and significant reduction of F1 offspring. The reduction was not significant relevant to the initial relative abundance of E. grisescens and E. obliqua. Detailed observations of mating opportunity showed that female mating frequencies of both species were not significantly affected by the absolute species density, but the mating success of E. obliqua females with conspecific males depended on species ratio. In addition, adding males to the other species resulted in lower number of offspring suggesting that the males' behaviour might be linked with mating interference. Males of both E. grisescens and E. obliqua could interfere the intraspecific mating of the other species, but the impact of the mating interference differed. These combined data indicated that asymmetric reproductive interference existed in E. grisescens and E. obliqua under laboratory conditions, and the offspring of the mixed species were significantly reduced. The long term outcome of this effect is yet to be determined since additional reproductive factors such as oviposition rate and progeny survival to adulthood may reduce the probability of demographic displacement of one species by the other in overlapping niches.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"243-250"},"PeriodicalIF":1.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34746353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Little is known about the ability of parasitoids to control the passionvine hopper (Scolypopa australis (Walker); PVH), which was introduced to New Zealand (NZ) in the 1800s and has since become a major economic pest of kiwifruit. However, in their native Australia, this species has not reached pest status, likely due to the presence of associated parasitoids. Understanding the ecology of parasitoids associated with PVH in their native range is a critical step in identifying potential biological control agents that could be used in NZ. In this study, PVH presence and occupancy on different plant species was determined and the PVH parasitoid fauna of NZ compared with the Australian fauna. Collections were undertaken in and around Melbourne, Australia, between December 2021 and May 2023 in public and private gardens, roadside verges and parklands. Parasitoids were reared from the nymphs and eggs of PVH and identified. Ten species of parasitoid were discovered to parasitise PVH, eight of which were new host records. Three parasitoids, Dryinus koebelei, Neodryinus nelsoni, and Neodryinus koebelei, were reared from PVH nymphs and seven parasitoids were reared from PVH eggs: Ablerus sp., Anastatus sp., Centrodora sp., Cheilonoeurus sp., Ooencyrtus sp., and unknown species belonging to the families Figitidae and Platygastridae. These new data have made a significant contribution to understanding the ecology of PVH in their native range.","PeriodicalId":9370,"journal":{"name":"Bulletin of Entomological Research","volume":" ","pages":"275-286"},"PeriodicalIF":1.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143708629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
