Do new Access and Benefit Sharing procedures under the Convention on Biological Diversity threaten the future of biological control?
The practice of biological control in relation to the principles of ABS is described, illustrated extensively by case studies and successes obtained with biological control, and the very limited monetary benefits generated in biological control are emphasised. Expand

Signs of positive selection in genes involved in chemoreception, detoxification and digestion, and copy number variation in the two latter gene families are found, suggesting an adaptive role for structural variation. Expand
Ultrastructure of the natural and factitious host eggs of Trichogramma galloi Zucchi and Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae)
Eggs of the factitious hosts were among the smallest and their volume was very close to each other, which would provide basic information for a better understanding of the host selection behavior and are useful for the development of a suitable artificial host egg for the in vitro rearing of these egg parasitoids.

Immature Development of Pseudacteon tricuspis (Diptera: Phoridae), an Endoparasitoid of the Red Imported Fire Ant (Hymenoptera: Formicidae)
The parasitization and development of P. tricuspis in two sizes of ants is described and the behavioral response of these ants to the attack of this fly is evaluated. Expand
Side‐effects of insecticides used in tomato fields on the egg parasitoid Trichogramma pretiosum Riley (Hym., Trichogrammatidae), a natural enemy of Tuta absoluta (Meyrick) (Lep., Gelechiidae)
Results showed that cartap and phenthoate were harmful, lambda‐cyalothrin and abamectin were intermediate, tebufenozide and teflubenzuron were harmless to slightly harmful, and nearly all the chemicals tested had significant sublethal effects. Expand
Egg Parasitoids in Agroecosystems with Emphasis on Trichogramma
The results show clear trends in diversity and hosts of Trichogramma in the New World, with emphasis in South America, and in biological control and Integrated Pest Management, which has implications for future generations of scientists and policymakers. Expand
Selectivity of insecticides to the egg parasitoid Trichogramma galloi Zucchi, 1988, (Hym., Trichogrammatidae)
The toxicity of the chemicals tested were dependent on the age of the parasitoid, affecting the immature survival, developmental time from egg to adult, parasitization capacity, adult longevity and the development of the filial generation. Expand
Sensilla on the antenna and ovipositor of the parasitic wasps Trichogramma galloi Zucchi and T. pretiosum Riley (Hym., trichogrammatidae).
The antenna and ovipositor of the wasps Trichogramma galloi and T. pretiosum were studied to identify their sensillar structure and their possible functions in the host selection process, as a support to the development of an artificial host for the in vitro rearing of these parasitoids. Expand

The braconid wasp Toxoneuron nigriceps induced qualitative and quantitative changes in the protein composition of the moth Heliothis virescens host hemolymph, and incubation of host derived tissues, parasitoid larvae and teratocytes in 35S conditioned media suggested PSPs were a product of teratocyte.

Population Dynamics and Growth Rates of Endosymbionts During Diaphorina citri (Hemiptera, Liviidae) Ontogeny
The density dynamics of the three endosymbionts associated with the psyllid D. citri was investigated by real-time quantitative PCR at different developmental stages and revealed a continuous growth of the symbionts during host development. Expand
