Phenotypic Selection by Parasitoids on the Timing of Life History in a Leafmining Moth

Abstract.-Direct measurements of phenotypic selection by parasitoids on quantitative traits in herbivorous insects have been rare. I analysed episodes of phenotypic selection on the timing of life-history events in a multivoltine leafmining moth, Phyllonorycter mespilella, and assessed the importance of hymenopterous parasitoids as selective influences. Phyllonorycter mespilella has two consecutive stages of larval development, the sap-feeding (SF) and tissuefeeding (TF) stages. Adult parasitoids host feed predominantly on SF larvae, and oviposit predominantly on TF larvae. Oviposition attack on TF larvae caused positive directional selection on the date of transition to the the TF stage (TF date) in the third generation of P. mespilella in one population in 1991. Overwinter mortality caused negative directional selection on TF date in the third generation in a second population in 1993. No directional or variance selection on TF date was detected in the second population in the second generation of 1993. Parasitoid females accepted SF larvae for oviposition more often in the fall generation than in summer generations in both populations. The relative frequencies of SF and TF larvae may alter the pattern of oviposition attack by parasitoids, and thus the form of phenotypic selection on TF date.

Development and Evaluation of a Control Decision Rule for First-Generation Spotted Tentiform Leafminer (Lepidoptera: Gracillariidae) in New York Apple Orchards

A pest control decision rule consisting of an action threshold and a sampling protocol was developed and evaluated for first-generation spotted tentiform leafminer, Phyllonorycter blancardella (F.). An action threshold of two eggs per leaf was chosen based on the criterion of preventing more than one first-generation mine per leaf. Two sequential classification sampling plans for first-generation eggs were developed, one based on variable intensity sampling and the other on the use of confidence intervals for stop limits. Both plans made use of the nested variance structure of leafminer egg counts and variance-mean models fit to estimated variance components. Performance of the two sequential procedures was studied using simulation and judged to be very similar. Use of either sampling plan required approximately 10-20 min. Over a 4-yr period, 87% of sampled orchards in western New York had leafminer populations that were below the threshold of two eggs per leaf. During this period, use of sample information to schedule insecticide treatments resulted in only one instance when a treatment may have been required and was not called for (n = 79).Widespread use of the decision rule would result in significant reductions in pesticide use with no attendant increase in risk to growers.
