The ectoparasitization of Coleophora alticolella (Lepidoptera) in relation to its aititudinal distribution

Abstract. 1. The parasitization of the larvae of Coleophora alticolella . feeding on Juncus squarrosus , was investigated at a series of altitudes from 15 to 520m above sea-level in northern England during 1977 and 1978.
2. Six species of primary parasitoid and one hyperparasitoid were reared from this host. Five of the primary parasitoids were ectophagous; only two specimens of the endoparasitoid, Gonotypus melanostoma , were reared.
3. All of the parasitoid species were recorded at 15 m but fewer at sites of higher altitude. Only one species, Scambus brevicomis , was recorded above 305 m, and none above 395 m. The hyperparasitoid, Tetrastichus endemus, was present only at 15 m.
4. Percentage parasitization was highest at 15 m; it was reduced from 51% to only 2% between 215 and 305 m in 1978. There was an increase in host density over this altitudinal range.
5. Three species, Scambus brevicomis. Elachertus olivaceus and Euderus viridis , accounted for most of the parasitization, but their relative proportions vaned at different altitudes.
6. The sex-ratios of the parasitoids reared from Coleophora alticolella ranged from 3.2% females for Scambus brevicomis , which is considered to also use larger hosts, to 99.4% females for Elachertus olivaceus , which develops by thelytokous parthenogenesis.
7. Euderus viridis and Scambus brevicomis started to attack the Coleophora alticolella larvae at a later date at 245 m than at 15 m, but attack by Elachertus olivacats was not delayed at the higher site.     

Larval Case Architecture and Implications of Host‐Plant Associations for North American Coleophora (Lepidoptera; Coleophoridae)1

The case‐bearing moths of North America are represented by a single genus, Coleophora, which contains approximately 144 described species. All are external seed or leaf miners that inhabit portable silk cases during most of the larval stage. Architectural and ecological characters from larval cases were used in cladistic analysis to investigate existing case groups for 32 North American species of Coleophora. Cladistic analysis confirmed monophyly of certain case groups, but not of others. Host‐plant preferences were also examined. The pattern of host plant use reflects more closely preference for certain plant tissues (seeds versus leaves) and growth forms (herbaceous versus woody) with exploitation of different plant taxa, rather than preference for certain plant taxa with exploitation of different plant tissues.     

Effects of scale on detecting interactions between Coleophora and Eriocrania leaf-miners

Abstract.

• 1 The possibility of interactions between leaf-miners in the genus Eriocrania and Coleophora serratella L. on birch (Betula pendula Ehrh. and B.pubescens Roth.) was studied via: (i) co-occurrence patterns on random samples of leaves; (ii) palatability of Eriocraniidae-mined leaves to C.serratella, in laboratory and field preference tests.
• 2 In the field, C.serratella and Eriocrania spp. fed on common leaves less frequently than expected by chance. This result is consistent with, and could be explained by, the avoidance of mined leaves shown by C.serratella in most of the feeding trials.
• 3 Avoidance was not observed at the between-tree level, i.e. the number of leaves mined by each type of insect was unrelated. However, when tree species was taken into account, an inverse distribution was observed: mine abundance was higher for Eriocrania spp. on B.pubescens, whereas for C.serratella it was higher on B.pendula.
• 4 B.pubescens leaves mined by Eriocrania spp. had consistently higher phenolic contents and were better at precipitating proteins than unmined leaves. These induced chemical changes could explain the reduced preference shown by C.serrate1la for Eriocrania mined leaves.
• 5 We speculate about the evolution of adult host-plant selection shown by these insects in response to potential larval interactions.

     

The diapause syndrome in the seed-eating caterpillar of Coleophora alticolella

Adult emergence in Coleophora alticolella held at 15 °C was accelerated by exposure to L18:D6 in autumn and midwinter. The effect decreased during winter and exposure of individuals, held at low temperature over winter, to L18:D6 or L6:D18 at 15 °C at the end of March resulted in the same mean emergence date. Long daylength experienced at 5 °C did not promote emergence nor did exposure to low temperature during winter. The number of adults emerging increased with the length of time cultures were held on short day but was always below 50% of the larvae. When larvae were exposed to L18:D6 and L6:D18 at 15 °C at the end of March, on long day 61% adults emerged and 39% remained in diapause, whereas on short day, 25% became adult and 75% remained diapausing larvae. The possibility of cohort splitting, with some individuals undergoing prolonged diapause, is discussed.     

The predation of predispersed Juncus squarrosus seeds by Coleophora alticolella (Lepidoptera) larvae over a range of altitudes in northern England

Seed production by the rush Juncus squarrosus and its subsequent predation by the larvae of the moth Coleophora alticolella were measured at a series of sites at different altitudes in northern England. The density of seeds produced is progressively reduced with increasing altitude. The density of larvae was greatest in the middle region of the transect. Seed predation was therefore highest at about 300 m. Predation was reduced to nil above 520 m, where the larvae were absent, but remained between 40 and 50% below 250 m. The density of predispersed seed surviving was greatest at the lowest site where the highest density of seeds was produced and predation was moderate. The lowest densities of surviving seeds were found around 300 m and also above 600 m where there was no predation but few seeds were produced. A similar density survived around 520 m as at 245 m, although the density of seed produced at 520 m was less than 30% of that at 245 m. The results are discussed in relation to the population dynamics of the moth in different parts of its altitudinal distribution.

The effects of foliage damage on casebearing moth larvae, Coleophora serratella, feeding on birch

ABSTRACT.

• 1 Mechanical damage to birch (Betula pendula Roth) leaves leads to an increase in the concentration of phenolic compounds, which spreads throughout the leaf within 8 days.
• 2 Coleophora serratella L. (Lepidoptera: Coleophoridae) apparently responds to this chemical change over a similar time scale. Within 24 h of pin-pricking leaves the casebearer moves from the immediate vicinity of the damage, but is just as likely to move to an undamaged portion of the damaged leaf as to vacate the leaf entirely. After 8 days mines on undamaged portions of damaged leaves were significantly smaller than mines on undamaged leaves.
• 3 Furthermore, Coleophora serratella reared on damaged trees took an average of 3 days longer to develop than those reared on undamaged trees.
• 4 It has been suggested that increased movement in response to damage-induced chemical changes causes hyperdispersed damage on plant foliage. Both within and between-leaf casebearer damage patterns were shown to be aggregated on birch.
• 5 Thus although mechanical damage can induce chemical and behavioural changes in the field, these are not reflected in the observed damaged patterns. We speculate on several possible reasons for this.
