Chemical footprints left behind by true bugs are perceived as contact kairomones by scelionid egg parasitoids. Female wasps
encountering a contaminated artificial substrate display a characteristic arrestment posture, holding the body motionless
and antennating the surface. In the system Nezara viridula (L.) and its egg parasitoid Trissolcus basalis (Wollaston), previous studies have shown that the kairomone mediating such behavior is part of N. viridula’s cuticular hydrocarbons (CHC) and furthermore that the wasp’s ability to discriminate host male and female footprints is mainly
based on the presence/absence of nonadecane (nC19). In this study, the effect of epicuticular waxes of leaves of broad bean, Vicia faba, on wasp responses to footprints of N. viridula females were investigated. Approximately 20% of T. basalis females displayed an arrestment posture when released on the adaxial leaf surfaces of broad bean plants with intact wax layer
and without host chemical contamination; whereas ∼70% of wasps displayed the arrestment posture when intact leaves were contaminated
by host female footprints. Adaxial leaf surfaces of broad bean plants dewaxed with an aqueous solution of gum arabic and afterwards
contaminated by N. viridula females induced arrestment responses in about 10% of female wasps; the same percentage of arrestment (10%) was observed when
the wasps were released on leaves contaminated by host females and subsequently dewaxed. The side of the polymer film that
was appressed to the leaf surface, peeled from the contaminated leaves, induced an arrestment posture in about 95% of observed
wasps. Scanning electron microscopy (SEM) revealed that the epicuticular waxes occurred as a film densely crystallized as
irregularly shaped platelets with spherical granules randomly distributed. These findings demonstrated that epicuticular waxes
of broad bean leaves can mediate the foraging behavior of T. basalis females by absorbing contact kairomones of the host. 相似文献

Children in refugee camps, and particularly those with disabilities, face unique challenges in accessing education and are at high risk of being marginalised. Best practices suggest that main-streaming is the optimal strategy for serving students with disabilities. This study examines the extent to which mainstreaming in a refugee camp helps to promote children's prosocial behaviours, taking into account their emotional and behavioural problems. In Kakuma Refugee Camp, Kenya, researchers collected data from the parents of children currently enrolled in special needs education centres (n=65) and from those formerly enrolled at these facilities who transitioned to mainstream classrooms (n=81). Children in mainstream schools functioned better in terms of prosocial behaviours, but this relationship disappeared when factoring in children's emotional and behavioural difficulties. In the context of a refugee camp, mainstreaming alone is not likely to help children's psychosocial and educational functioning, which requires dedicated supports, appropriate facilities and infrastructure, and a dual focus on disability-specific and disability-inclusive initiatives. 相似文献
