Prey consumption and conversion efficiency in females of two feral populations ...

Macrolophus pygmaeus (Rambur, 1839) (Hemiptera: Miridae) is a polyphagous predator used in programs of biological control and integrated pest management as a natural enemy against small arthropod pests including whiteflies, thrips, spider mites and aphid. This mirid is also successfully mass reared under factitious prey for commercial purposes. In the present study we assessed and compared the prey consumption,...

Do dominant native ants outcompete the invasive Argentine ant in Mediterranean ...

The invasive Argentine ant (Linepithema humile) poses a significant threat to ecosystem stability worldwide. In Mediterranean citrus ecosystems, its spread may be limited by interactions with dominant native ant species. We conducted laboratory experiments to investigate the competitive dynamics between Argentine ants and two major native species, Tapinoma nigerrimum and Lasius grandis. At the individual level,...

Agricultural practices for biodiversity enhancement: evidence and recommendatio...

Agricultural expansion and intensification worldwide has caused a reduction in ecological infrastructures for insects, herbaceous plants, and vertebrate insectivores, among other organisms. Agriculture is recognized as one of the key influences in biodiversity decline, and initiatives such as the European Green Deal highlight the need to reduce ecosystem degradation. Among fruit crops, grapes are considered one...

Towards sustainable agriculture: A critical analysis of agrobiodiversity assess...

Agriculture intensification has driven the loss of biodiversity at a global level. The imple- mentation of strategies to conserve and promote biodiversity in agricultural areas can be favoured by adequate assessment methods that foster the awareness of decision makers about the impact of management practices. This paper presents a state-of-the-art review of assessment methods of the overall biodiversity in agri...

As cigarrinhas-verdes da vinha na região do Alentejo

As cigarrinhas-verdes (Hemiptera, Cicadellidae) são uma praga de grande importância nas vinhas do Alentejo, particularmente a espécie Jacobiasca lybica. São raros os estudos que envolvem a opinião dos viticultores sobre os problemas com os quais se deparam no combate às cigarrinhas, pelo que este estudo tem como objetivo conhecer as perceções dos viticultores relativamente à importância das cigarrinhas verdes n...

Melanaspis corticosa: a new insect pest of olive trees in Europe

The presence of the South African Obscure Scale, Melanaspis corticosa (Brain) (Hemiptera, Diaspididae), was detected infesting olive trees, in Portugal. The identity of the scale insect was confirmed based on both morphological and molecular studies. Until now, this species was only known in a few African countries, including Guinea, Mozambique, South Africa and Zimbabwe. This is the first record of this specie...

Contrasting Phenotypic Variability of Life-History Traits of Two Feral Populati...

Tuta absoluta is a major pest attacking tomato crops. This invasive species emerged in Europe (Spain) in 2006, and 3 years later it spread to Portugal. In 2009/2010, it was recorded for the first time in the Azores archipelago. Macrolophus pygmaeus is a predator widely used as biological control agent against the tomato leaf miner. This study contrasted the life-history traits and population growth parameters o...

Eradication programs against non-native pests and pathogens of woody plants in ...

When a non-native species succeeds in establishing in a new habitat, one of the possible responses is to attempt its eradication. In the present study, we analysed European eradication programmes against non- native pests and pathogens of woody plants (PPWP) from 1945 to date. Our main goal was to identify which factors affect the success of an eradication programme, reinforcing guidelines for future eradica- t...
