Invertebrate pest control within both agricultural and horticultural production systems continues to present many challenges. Over the past decades the commonly used method for pest control has been the direct application of chemical products. However, in response to environmental, economic, and other problems associated with the over-reliance on chemical insecticides there has been an increasing drive towards the development of Integrated Pest Management (IPM) approaches. Many IPM strategies are now well developed under protected environments. However, within the open field in many situations targeted success is yet to be achieved. This special issue will seek to showcase original articles and reviews by leading research entomologists and associated experts. Articles presented will focus on the development and implementation of IPM strategies against various major arable and horticultural invertebrate pests (both indigenous and invasive species).

Energy production systems for isolated communities lacking national energy grids are, in many countries, associated with first energy access of rural or developing regions. Those communities require innovative design methods to select relevant solutions for sustainable developments in a context of continuously strengthening climate change conditions. The design of an innovative solution goes through multiple stages. After identifying opportunities, analyzing a context and identifying a problem, we are interested here in the process of imagining solutions and guiding reflections so that the resulting solutions are sustainable. Sustainability is analyzed from technical, economic, environmental and social angles. The two main visions for imagining solutions, the value proposition and the technical solution, are discussed. We are then developing a multi-criteria method of sustainable design to imagine the technical solution of an electricity production system in a context of first access to energy for isolated communities. This method serves as decision and discussion support between all stakeholders (community, decision makers, project managers) so that they collectively build a sustainable solution. As the exchanges progress, criteria from different fields meet and complement each other to allow the development of the specifications for the energy production solution which will be ultimately developed.

The article analyzes energy supply alternatives for modernised public nearly zero energy buildings. The paper examines alternative energy production systems such as heat pumps (air-water and ground-water), solar collectors, adsorption cooling, biomass boiler, solar photovoltaic, wind turbines and combinations of these systems. The simulation of the analysed building energy demand for different energy production alternatives has been performed using TRNSYS modelling software. In order to determine an optimal energy supply variant, the estimated results of energy, environmental, and economic evaluation have been converted into non-dimensional variables (3E) using multi-criteria analysis. Article in Lithuanian. Santrauka Siekiant beveik nulinio energijos balanso modernizuotame viešosios paskirties pastate, nagrinėjamos aprūpinimo energija alternatyvos. Tiriamos šios alternatyvios aprūpinimo energija sistemos: šilumos siurbliai (gruntas–vanduo ir oras– vanduo), saulės kolektoriai, adsorbcinė vėsinimo mašina, biokuro katilas, saulės elementai, vėjo jėgainė – ir šių sistemų deriniai. Skirtingų aprūpinimo energija variantų energijos poreikiai modeliuojami TRNSYS (The Transient System Simulation Program) modeliavimo programa. Siekiant nustatyti optimalų aprūpinimo energija variantą, gauti energinio, ekologinio ir ekonominio vertinimų rezultatai daugiakriterės analizės būdu perskaičiuojami į nedimensinius rodiklius (3E).
