Learning pays off: influence of experience on host finding and parasitism in Lariophagus distinguendus

Abstract. 1. The influence of experience on egg maturation, parasitism rate, and behaviour during host searching was investigated for Lariophagus distinguendus (Först.) (Hymenoptera: Pteromalidae) parasitizing larvae of the granary weevil Sitophilus granarius (L.) in grains of wheat Triticum aestivum L.
2. Dissection of female parasitoids and parasitism bioassays at high host density revealed that experience with hosts (e.g. by oviposition or by host feeding) is not required either for triggering oogenesis or for oviposition.
3. In parasitism experiments at low host density, when single host-infested grains were offered within a bulk of healthy grains, host finding and parasitism rate were increased by experience.
4. Behavioural observations revealed that searching time required for finding an infested grain was shorter for experienced parasitoids than for naive parasitoids, because travel time from grain to grain is shorter for experienced parasitoids, and because experienced parasitoids spend less time than naive parasitoids on non-infested grains.
5. In conclusion, experience due to host exposure increases parasitism and thereby the fitness of the parasitoids. It is discussed that this increase is more likely due to learning than to different egg load dynamics of experienced parasitoids.     

Sex ratio manipulation in response to host size in the parasitoid wasp Spalangia cameroni: is it adaptive?

Many species of parasitoid wasps produce a greater proportionof sons in small than in large hosts. As described by the host-sizemodel, natural selection is becoming a standard explanationfor the evolution of this phenomenon. We examined a criticalassumption of the host-size model, that host size has a morepositive effect on female than on male reproductive success.In laboratory experiments with the parasitoid wasp Spalangiacameroni, females that developed on larger hosts contained moreeggs at emergence. However, more eggs did not translate intomore offspring, at high or low density and regardless of whethera female had to burrow to reach hosts. The size of host on whicha female developed was also unrelated to her longevity, regardlessof the presence or absence of hosts. The size of host on whicha male developed had no effect on his sperm production or abilityto inseminate females, regardless of whether insemination abilitywas measured by the amount of sperm transferred to a female,by the proportion of a male's mates that produced any daughters,or by the proportion of daughters that a male's mates produced.Thus, despite data on multiple measures of fitness under a rangeof conditions, sex ratio manipulation in response to host sizein S. cameroni does not appear to be adaptive, and another explanationis needed.

Assessment of Ceratitis capitata (Diptera,Tephritidae) pupae killed by heat or cold as hosts for rearing Spalangia cameroni (Hymenoptera: Pteromalidae)

In this work, we study the suitability of using dead medfly Ceratitis capitata pupae, killed by heat- or cold-shock, for the mass rearing of Spalangia cameroni, a pupal parasitoid of key pests. 100% mortality of medfly pupae could be accomplished with cold-shock at –20°C for 60 min or with heat-shock at 55°C for 30 min. Neither parasitism percentage nor sex ratio of the offspring differed significantly among heat-shocked, cold-shocked and untreated pupae. In addition, there was no significant difference in the percentage of parasitoids that aborted (♂♂ or ♀♀) among pupal treatments. Some of the pupae were covered with peat because the third larval instar of the medfly buries itself before pupation. However, the buried pupae were not parasitised at a greater or lesser rate than those not covered with peat. The percentage of parasitism was also unaffected by whether the pupae had been killed recently or had been stored at between 4°C and 6°C over 15 or 30 days. The use of dead hosts and later storage permitted the following: (a) the use of hosts over long periods of time; (b) a rapid increase in parasitoid numbers and (c) the availability of pupae killed at the most suitable postpupation times for the production of parasitoids. Furthermore, in biological control projects, the use of dead parasitised pupae in the field avoids the risk of enhancing the pest and allows an increase in parasitism in the field through the use of pupae treated with cold- or heat-shock.
