Sporodochia are dense masses of fungal hyphae bearing asexual conidia. ForFusarium oxysporum, sporodochia are known to produce airborne conidia and enhance the dissemination of this otherwise soilborne pathogen. Sporodochia are small and transient, and they are documented for only a fewformae specialesofFusarium oxysporum. This study reports airborne conidia and sporodochia produced byF. oxysporumf. sp.fragariae, the cause of Fusarium wilt of strawberry, in the Monterey Bay region of California. Sporodochia were consistently present in Fusarium wilt-afflicted strawberry fields and were discovered in 21 of 24 Fusarium wilt-diseased fields. Only necrotic tissues were observed bearing sporodochia, and they were most frequently observed on petioles and peduncles. Sporodochia grew significantly longer up peduncles than petioles, extending further away from the base of the plant and toward parts of the canopy more exposed to wind. A stolon hosted the longest stretch of sporodochial growth, found covering the stolon's entire 35 cm length and also the base of the daughter plant. Macroconidia were produced by all sporodochia samples, and we did not find microconidia on any samples. An initial series of experiments confirmed the potential for conidia produced by sporodochia to disperse with wind over short distances. The prevalence of sporodochia producing airborne spores ofF. oxysporumf. sp.fragariaehas great importance for disease management and biosecurity.

Host plant and habitat preferences of Lygus bugs: consequences for trap cropping applications

Lygus bugs (Hemiptera: Miridae) can damage economically important crop plants by feeding on their active growing points, such as the apical meristem and buds, and reproductive organs, such as flower buds, flowers, seeds, and fruits. Plant injury is a combination of mechanical damage by the stylet and the effects of saliva, which contains enzymes that break the plant cells. On some occasions, oligophagous Lygus species can act as biocontrol organisms when predating on eggs and larvae of pest insects. This review summarises studies where trap crops have been used to control Lygus bug populations on various crops and to reduce damage to crops. We also focus on the factors that affect the host plant and habitat selection of the highly polyphagous Lygus bugs and discuss the reasons why a less favourable host plant in the laboratory might become attacked by Lygus bugs in the field. An analysis of rapidly developed worldwide Lygus damage problems in conifer nurseries in the late 1970s and early 1980s is presented as an example of how rapidly Lygus bugs can adapt to changes in environmental conditions and new types of crops. We suggest that the rate of crop irrigation and the efficiency of weed control could be factors augmenting Lygus populations and the severity of Lygus damage. These factors should also be considered in the planning of trap crop strategies for Lygus spp.
