Teknik perbanyakan massal parasitoid Anagrus nilaparvatae (Pang et Wang) (Hymenoptera: Mymaridae) dengan kotak plastik

Jurnal Entomologi Indonesia, 2015
Anagrus nilaparvatae (Pang et Wang) is an egg-parasitoid of rice brown planthopper (Nilaparvata lugens Stål). The objective of this study was to develop a mass-rearing technique of A. nilaparvatae.

Lack of phenotypic and evolutionary cross-resistance against parasitoids and pathogens in Drosophila melanogaster

, 2012
BackgroundWhen organisms are attacked by multiple natural enemies, the evolution of a resistance mechanism to one natural enemy will be influenced by the degree of cross-resistance to another natural enemy.

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, EarlyView.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

First field evidence that parasitoids use upwind anemotaxis for host-habitat location

, 2007
The direction of flight of natural populations of Phradis interstitialis (Thomson), Tersilochus obscurator Aubert (both Hymenoptera: Ichneumonidae), and Platygaster subuliformis (Kieffer) (Hymenoptera: Platygastridae), parasitoids of three crucifer ...

Perceptions, challenges and determinants of management strategy choices for combating fall armyworm (Spodoptera frugiperda) infestation in Ghana

Pest Management Science, EarlyView.
Despite high awareness of fall armyworm, a significant gap remains in the use of sustainable and effective control measures. Farmers predominantly perceive synthetic pesticides as ideal despite studies highlighting botanical and traditional methods as more sustainable.

Optimal control and multitrophic physiologically‐based models: The binomial for successful decision support systems in insect pest management

Pest Management Science, EarlyView.
Decision‐making in integrated pest management (IPM) corresponds to an optimisation problem where the plant–pest dynamics and the control actions are constraints and where the objective function accounts for the costs of the treatments and the total income at the harvest time.

Intrinsic competition and its effects on the survival and development of three species of endoparasitoid wasps

, 2009
In natural systems, pre-adult stages of some insect herbivores are known to be attacked by several species of parasitoids. Under certain conditions, hosts may be simultaneously parasitized by more than one parasitoid species (= multiparasitism), even ...

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Identification of broadly expressed nervous system‐related genes as effective RNAi targets in the brown marmorated stink bug, Halyomorpha halys

Pest Management Science, EarlyView.
Broadly expressed genes outperformed brain‐enriched neural targets as RNAi candidates in Halyomorpha halys. Microinjection of dsRNA targeting alpha‐soluble NSF attachment protein (Asnap) or Ras opposite protein (Rop) caused strong feeding suppression and near‐complete mortality, identifying them as promising targets for future oral or spray‐based RNAi ...
