A teaching experiment to foster the conceptual understanding of multiplication based on children's literature to facilitate dialogic learning [PDF]
, 2005 The importance of conceptual understanding as opposed to low-level procedural knowledge in mathematics has been well documented (Hiebert & Carpenter, 1992). Development of conceptual understanding of multiplication is fostered when students recognise the

Cladistics, EarlyView.Abstract Automated insect identification systems hold significant value for biodiversity monitoring, pest management, citizen science initiatives and systematic studies, particularly in an era of declining expertise in insect taxonomy. However, current deep learning approaches often rely on standardized specimen photos from limited‐angles and ...

Intraguild predation between the invasive ladybird Harmonia axyridis and non-target European coccinellid species [PDF]
, 2018 The coccinellid Harmonia axyridis (Pallas) has been used for augmentative and classical biological control in many environments. More recently it has invaded large parts of Europe and negative effects for native populations of aphidophagous coccinellids ...

Entomologia Experimentalis et Applicata, EarlyView.In this study we measured the impact of access to sugar and hosts on the longevity and fecundity of six Trichogramma species: T. cacoeciae, T. chilonis, T. minutum, T. leptoparameron, T. pintoi and T. sibericum. The impact of food differed among species, but there was a general tendency of increased life expectancy and potential fecundity with sugar ...

The Effects of Crop Type and Production Systems on the Activity of Beneficial Invertebrates [PDF]
, 2007 Beneficial invertebrate activity (13 groups) was assessed in five crop types on a split-plot experimental system in northern England using pitfall trapping and suction sampling in May-October 2005.

Entomologia Experimentalis et Applicata, EarlyView.Predation methods vary widely in their ability to quantify biological control. Estimating predation rates (the number of prey killed per predator per time unit) is crucial. Combining predation rates with predator abundance yields real‐time field estimates of pests consumed.

Forgotten natural enemies: Interactions between coccinellids and insect-parasitic fungi
European Journal of Entomology, 2008 The role of predators and parasitoids in the regulation of insect populations is widely reported in the context of both pest and non-pest insects. However, this is not the case for pathogens (entomopathogens).

Plants for predators - a participatory experiment [PDF]
, 2006 Encouraging natural enemies by growing attractant plants is a highly effective method of pest control in organic systems. However, it is important to establish which plants are most effective at attracting benefi cial insects.

The Ecology and Evolution of Ant- Aphid Interactions
, 2009 The evolution of species interactions is a fascinating subject, and one of vital importance if we are to understand how biological communities change over time.
