Abstract The effectiveness of augmentative biological control using parasitoids often depends on their physiological state and the pest population density at time release. Tamarixia triozae (Burks) (Hymenoptera: Eulophidae) is a primary host-feeding parasitoid serious invasive Bactericera cockerelli (Šulc) (Hemiptera: Triozidae). Here we investigated effects adult diets (honey, water, yeast, ho...

Speech is the most natural form of communication for human beings and is often described as a unimodal communication channel. However, it is well known that speech is multimodal in nature and includes the auditive, visual, and tactile modalities. Other less natural modalities such as electromyographic signal, invisible articulator display, or brain electrical activity or electromagnetic activit...

As part of my research on the mass production and augmentative release of ladybirds, I reviewed the primary research literature to test the prediction that ladybirds are effective aphid predators in greenhouses. Aphid population reduction exceeded 50% in most studies and ladybird release rates usually did not correlate with aphid reduction. The ratio of aphid reduction/release rate was slightly...

• Pachycrepoideus vindemmiae is a cosmopolitan drosophilid parasitoid. This pupal parasitoid was released in hoop houses for D. suzukii control. Trials Minnesota, Oregon and California had inconsistent results. Only one trial showed elevated parasitism levels release plots. Spotted wing drosophila, Drosophila , native to East Asia but has become major pest of soft-skinned fruit crops its invade...

The use of an aided augmentative communication system to achieve effective communication between the pediatric dentist and the child with cerebral palsy is described. This type of communication involves symbols placed on a communication board and may be used together with conventional behavior management techniques for successful delivery of dental treatment. A multidisciplinary team caring for...

Many adults with autism spectrum disorders have complex communication needs and may benefit from the use of augmentative and alternative communication. However, there is a lack of research examining the specific communication needs of these adults, let alone the outcomes of interventions aimed at addressing them. The aim of this study was to explore the views and experiences of support workers ...

Individuals who rely on augmentative and alternative communication (AAC) devices to support their communication often have physical movement challenges that require alternative methods of access. Technology that supports access, particularly for those with the most severe movement deficits, have expanded substantially over the years. The purposes of this article are to review the state of the s...

Two natural enemy species are frequently released simultaneously to control one pest species in augmentative biological control in greenhouses. Intraguild predation (IGP) and interspecific competition between natural enemies might affect the biological control. IGP occurs between two parasitoids, between one parasitoid and one predator, and between two predators. Although unidirectional IGP has...
