Here, results of larval development are presented for the bunny‐tailed moth, Ochrogaster lunifer. The processionary larvae of this species live in a communal cohort, and moult en masse in the silken nest spun at the base of their host tree (usually a phyllodinous acacia). The exuviae, which remain buried in the accumulated silk and frass of the nest, provide a life history record of the larval cohort. Larval exuviae were collected from 773 cohorts at 37 localities in southeastern Queensland between November 1993 and May 1994. The 6,948 exuviae examined were from cohorts feeding on Acacia concurrens Pedley. Head‐capsules showed a strongly uniform geometric increase in size through eight larval instars, supporting the Brooks‐Dyar rule. The number of instars did not vary between trees or localities. A bimodal distribution of final instar head‐capsule widths was shown to be a sexual dimorphism, and similar bimodal distributions were found for instars V‐VII. Pupal size was also sexually dimorphic. The geometric size increase from one larval instar to the next holds for both males and the larger females. The geometric rule was tested using larval cohorts reared on A. concurrens in the greenhouse through instars I‐IV; development was remarkably similar to that in the field. Larval growth patterns of O. lunifer are very different from the structurally similar bag‐shelter moth. The ability to distinguish different instars of O. lunifer with a high degree of precision from field‐collected exuviae will allow accurate comparisons of development, survival and dispersal of larvae in different group sizes, on different trees and in different localities.","PeriodicalId":8614,"journal":{"name":"Australian Journal of Entomology","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1996-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1440-6055.1996.tb01402.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63106954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The levels of oviposition and seed set determined in the laboratory and glasshouse trials were significantly correlated with the field parameter. Number of eggs per spikelet was the laboratory parameter most highly correlated with the field result (r = 0.93, P < 0.01). Studies on the rate of oviposition under the conditions of the bioassay confirmed 6 h as an appropriate interval to expose panicles to midges. A laboratory method based on estimating the number of eggs produced by 5 midge females on 50 flowering spikelets in 6 h at 25°C and 75%orh is suggested as a practical method of testing for level of resistance in those sorghum hybrids showing ovipositional antixenosis.","PeriodicalId":8614,"journal":{"name":"Australian Journal of Entomology","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"1996-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/j.1440-6055.1996.tb01373.x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63105952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 17,729 specimens were collected at 55 sites in Queensland, New South Wales and the Northern Territory. H. balciunasi was found to be relatively common, being collected in 57% of 550 collections of hydrilla. Although larvae were collected from 17 aquatic plant species, hydrilla was the preferred host for this fly, with 97% of the specimens collected from it. Based on these field data, H. balciunasi was exported to quarantine in the United States of America in 1988 for laboratory evaluation of its host‐range. Quarantine studies confirmed its safety as a biological control agent, allowing its release in the field in Florida in 1989.
