Most of the detrimental effects of using conventional insecticides to control crop pests are now well identified and are nowadays major arguments for replacing such compounds by the use of biological control agents. In this respect, the bacterium Bacillus thuringiensis var. kurstaki and Trichogramma (Hymenoptera: Trichogrammatidae) parasitic wasp species are both effective against lepidopterous pests and can actually be used concomitantly. In this work, we studied the potential side effects of… 
Bacillus thuringiensis var. kurstaki bioinsecticide induces growth defects and developmental delay of the non-target organism Drosophila melanogaster by disturbing homeostasis of the larval intestine
TLDR
It is shown that unintended effects of Btk products impede gut physiology but can be mitigated by the regenerative capacity of the gut, the commensal flora composition and the diet composition, and the ability of the larval midgut to maintain its integrity upon Btk aggression.
Side Effects of Pesticides on the Olive Fruit Fly Parasitoid Psyttalia concolor (Szépligeti): A Review
TLDR
This manuscript reviews the current literature on lethal and sublethal effects of insecticides, fungicides, herbicides, and biopesticides on P. concolor and concludes that the appropriate timing and application of selective chemical treatments provides the opportunity to incorporate this parasitoid in the IPM of B. oleae.
Adverse effects of Bacillus thuringiensis bioinsecticide on non-target Drosophila species
TLDR
While recommended doses had no effect on non-target Drosophila species, the accumulation of Bt bioinsecticides in the environment could have adverse side-effects on the populations of these species and therefore their associated communities.
Biological parameters of three Trichogramma pretiosum strains (Riley, 1879) (Hymenoptera: Trichogrammatidae) on eggs Helicoverpa armigera (Hübner, 1805) (Lepidoptera: Noctuidae)
TLDR
Trichogramma pretiosum strain TM obtained a better egg development of H. armigera on laboratory conditions, according with the evaluated biologic parameters.
Bacillus thuringiensis Bioinsecticides Induce Developmental Defects in Non-Target Drosophila melanogaster Larvae
TLDR
Using doses that could be reached in the field upon sprayings, it is shown that Btk products impair growth and developmental time of the non-target dipteran Drosophila melanogaster, and it is showed that the larval midgut maintain its integrity upon Btk aggression.
Differential side-effects of Bacillus thuringiensis bioinsecticide on non-target Drosophila flies
TLDR
Testing the effects of chronic exposure to commercial Bt formulations on eight non-target Drosophila species present in Bt-treated areas suggests a synergy between the formulation compounds (spores, cleaved toxins, additives) might induce the bioinsecticide effects on larval development.
Parâmetros biológicos e exigências térmicas de Trichogramma pretiosum sobre ovos de Helicoverpa armigera
TLDR
The objective of this work was to determine the biological parameters and thermal requirements of the Trichogramma pretiosum TM strain reared on Helicoverpa armigera eggs, and the highest parasitoid emergence rates occurred at temperatures of 22, 25 and 28°C.
Biological parameters and thermal requirements of Trichogramma pretiosum reared on Helicoverpa armigera eggs
The objective of this work was to determine the biological parameters and thermal requirements of Trichogramma pretiosum TM strain reared on Helicoverpa armigera eggs. A card containing 20 eggs of H.
Effects of Transgenic Crops on the Environment
TLDR
The increase in the number and types of traits being engineered into crops indicates a need for assessments that account for different types of potential environmental effects beyond those associated with herbicide and pest resistance.

TLDR
Wasps exposed to tobacco leaves treated with monocrotophos died within 24 h, but were not affected by exposure to Dipel®-treated leaves, and topical treatment with B. thuringiensis did not decrease posttreatment longevity, although there did seem to be an initial effect on survival.

TLDR
The impact of host feeding on the fecundity and longevity of females, in absence of host or food, and on the fitness of their progeny is measured, indicating that their fitness was affected.
Common Virulence Factors and Tissue Targets of Entomopathogenic Bacteria for Biological Control of Lepidopteran Pests
TLDR
This review focuses on common insecticidal virulence factors from entomopathogenic bacteria with special emphasis on two insect pathogenic bacteria Photorhabdus and Bacillus, two bacteria with dissimilar life styles, and the implications of the nervous system in biocontrol.

TLDR
This is the first experimental demonstration of Bt behaving as a specialized insect pathogen in the field, and a near-epidemic population structure dominated by a single entomopathogenic genotype (ST8) in sprayed and unsprayed enclosures is found.
