Oviposition Sites

AbstractOviposition sites of Phlyctinus callosus (Schoenherr) in an apple and a nectarine orchard in the South Western Cape, South Africa, were investigated. No eggs were found on the fruit trees, only in different fractions of the orchard floor, viz. in orchard weeds, leaf litter and soil. Significantly more oviposition took place in plant material on the orchard floor than in the top 20 mm of the soil. Microscopic dissection of samples of such plant material revealed that females prefer to oviposit in confined or hollow spaces in moist, live or decaying plant tissue on the soil surface or in weeds comprising the cover-crop. P. callosus females favoured certain weeds above others for oviposition. The dispersion pattern of eggs in the cover-crop was contagious. The implications of the observed ovipostion behaviour in terms of control strategy, and for exploitation in a monitoring system for this species, are discussed.

Mating Tests

AbstractThe false codling moth is a polyphagous pest of various kinds or fruit, and it has expanded its geographical distribution and host range. The expanding host range could result in subspecies requiring varied pest management options. Laboratory no-choice cross-mating tests were conducted to establish whether Thaumatotibia leucotreta individuals from six areas and three host species, in South Africa, share mating characteristics and belong to the same subspecies or strain. The no-choice cross-mating tests indicated that all individuals in self- and out-crosses readily mated within 24 h with those derived from different hosts and areas. The mtDNA results confirmed that all individuals formed one group or clade. Overall, the results indicate that T. leucotreta individuals from the six areas and three host species in the Western Cape Province and two other provinces in South Africa represent a single genetical species. The results imply that similar control options can be effective across host ranges and distribution areas.
