Understanding methods of vector control is essential to vector-borne disease (VBD) management. Vaccines or standard medical interventions for many VDBs do not exist or are poorly developed so disease control is focused on managing vector numbers and dynamics. This involves understanding not only the population dynamics but also the population genetics of vectors. Using mosquitoes as a case study, in this chapter, the modern genetics-based methods of vector control (self-limiting, self-sustaining) on mosquito population and disease suppression will be reviewed. These genetics-based methods highlight the importance of understanding the interplay between genetics and ecology to develop optimal, cost-effective solutions for control. The chapter focuses on how these genetics-based methods can be integrated with other interventions, and concludes with a summary of regulatory and policy perspectives about the use of these approaches in the management of VBDs.

Temporal Variance

What prevents populations of a species from adapting to the novel environments outside the species' geographic distribution? Previous models highlighted how gene flow across spatial environmental gradients determines species expansion vs. extinction and the location of species range limits. However, space is only one of two axes of environmental variation — environments also vary in time, and we know temporal environmental variation has important consequences for population demography and evolution. We used an individual based evolutionary model to explore how temporal stochasticity in environmental conditions influences the spread of populations across a spatial environmental gradient. We find that temporal stochasticity greatly alters our predictions for range dynamics compared to temporally static environments. When temporal variance is equal across the landscape, the fate of species (expansion vs. extinction) is determined by the interaction between the degree of temporal autocorrelation in environmental fluctuations and the steepness of the spatial environmental gradient. When the magnitude of temporal variance changes across the landscape, stable range limits form where this variance becomes large enough to prevent local population adaptation and persistence. These results illustrate the pivotal influence of temporal stochasticity on the likelihood of populations colonizing novel habitats and the location of species range limits.

The Difference

- The same common name can designate different scientific objects, whose trajectories in history we can trace. Individual is an interesting case study, and a typical example of a constitutive metaphor in science. The old meaning, moving from philosophy to science, has changed along two centuries. The new meaning in population genetics is based on the difference among individuals. Thus, individual as a constitutive metaphor becomes the real epistemological engine of modern evolutionary theories.

A New Species

The first records of Heterolocha laminaria (Herrich-Schäffer, 1852) (Lepidoptera: Geometridae) in Ukraine are presented. Until the recent past, the European registrations of H. laminaria had been only reported from Rostov Region of Russia. New records were made at several localities within Dnipropetrovsk, Zaporizhzhia, Odesa and Poltava regions, in Southern, South-Western, South-Eastern and Central Ukraine. These findings were revealed from mid-June to mid-August in various habitat types: steppes, artificial deciduous and mixed forests, agrocenosis. The current records significantly shift westward the range limits of H. la­mi­na­ria. Thus, a newly-discovered locality in Savran Forest is the westernmost point in the entire species range. Most likely the westward expansion of this species has occurred in recent decades. The habitats, adults, and male genitalia of H. laminaria are illustrated.
