“…Thus, storage at 4.5 °C is the best option among the conditions that have currently been evaluated. Cold storage is a technique used to increase insect shelf-life in mass rearing systems [ 93 , 94 , 95 ] and, provided this does not adversely affect subsequent performance [ 92 ], allows individuals to be kept until needed in the laboratory [ 96 , 97 ] or in the field [ 98 , 99 ], thus synchronizing artificial production and release with both the culture of the laboratory hosts and the population dynamics of the target pest [ 92 , 100 , 101 ]. Despite the advantages of cold storage, there may be some negative effects such as increased mortality caused by physical or metabolic injuries (e.g., osmotic stress or anoxia) or reduced quality due to reduction or elimination of endosymbiont bacterial populations or effects on mobility, responses to chemical cues, learning capacity, fecundity, and offspring sex ratio [ 102 ].…”

Many species of long-horned beetles are invasive pests causing significant economic damage in agro-forestry systems. They spend the majority of their life-cycle concealed inside natural wood or wooden packaging materials and are largely protected from adverse environmental conditions and pesticide sprays. Biological control via parasitoid natural enemies including members of the bethylid genus Sclerodermus, has proven effective against some long-horned beetles that are invasive in China. In Europe, the biocontrol potential of native Sclerodermus species is being evaluated with a view to developing efficient mass-rearing techniques and then actively deploying them against invasive Asian beetles. Here, we continue evaluations of S. brevicornis by establishing that groups of females that have already reared offspring to emergence are capable of reproducing subsequent hosts and by evaluating the lifetime reproductive capacity of individual females provided with successive hosts. Additionally, we assess the laboratory shelf-life of adult females stored for different times at different temperatures including cold storage, and then assess the post-storage reproductive performance of groups of females provided with a single host. We found that adult female longevity declines with increasing storage temperature and that most aspects of subsequent performance are negatively affected by high temperatures. The adaptability to low temperature storage enhances the suitability of S. brevicornis to mass-rearing programs and thus biocontrol deployment.

“…In vitro production of biologically and behaviourally normal Tachinidae in complete absence of the host and in artificial diet free of any component coming from hosts has been developed for four species (Dindo and Grenier, 2014) and there is a considerable volume of publications dealing with the different aspects of this process (Dindo et al, 2007(Dindo et al, , 2006Bratti and Nettles, 1992;Mellini and Campadelli, 1996). The success of in vitro rearing depends on the biology of the parasitoid and the endocrinological relationship between host and parasitoid, host-dependant parasitoids generally being more difficult to rear on artificial medium (Dindo, 1998;Thompson, 1999).…”

The American palm weevil, Rhynchophorus palmarum, is the main primary pest of palms in tropical America and the principal vector of the red ring disease, the major phytosanitary problem of coconut and oil palm in South America. The current management of the problem is based on the capture of adult weevils with aggregation pheromone and the elimination of diseased palms, a system difficult to implement for smallholder producers. Biocontrol agents of the weevil, the tachinid parasitoids Billaea spp., are known with limited distribution in Bahía State of Brazil. Their introduction and release in affected areas could greatly improve the natural control of the weevils. Furthermore, these parasitoids are known to attack palm-boring weevils in five different genera and could be a new control option for the red palm weevil, Rhynchophorus ferrugineus, the worst pest of palms worldwide. The collection, rearing and study of these parasitoids for introduction in new areas are the aim of this study. A detailed analysis of the necessary steps to comply with regulatory aspects and a research programme to ensure biosafety is described.

“…Tachinidae represent the largest and most important group of nonhymenopteran parasitoids and are notable because of their diverse oviposition strategies that allow them to parasitize hosts in varying environments. For example, many tachinids are unique because of their capacity to attack hosts hidden in the soil or in plants (Dindo and Grenier 2014).…”

“…Exorista larvarum can be mass produced relatively easily both in vivo, using larvae of the greater wax moth, Galleria mellonella (L.) (Lepidoptera: Pyralidae), as a factitious host, and in vitro, on artificial media composed of crude components (Dindo and Grenier 2014). This parasitoid may thus be considered as a good candidate for augmentation, as the success of this type of biological control is largely based on the development of efficient techniques for culturing the entomophagous species involved (Greathead 1986).…”

“…A few studies were especially devoted to the influence of adult food on the performance of tachinid parasitoids. In captivity, adult tachinids are often provided with lump sucrose and/or honey solutions, which may be gelled or supplied through cotton balls (Mellini and Coulibaly 1991, Quednau 1993, Dindo and Grenier 2014). Also, in the stock colony of E. larvarum maintained at the Department of Agricultural and Food Science (DISTAL; University of Bologna, Italy), the captive flies were routinely fed on lump sucrose and cotton balls soaked in a honey and water solution, but the effects of adult food had not been studied in detail.…”

Exorista larvarum (L.), a polyphagous gregarious larval parasitoid of lepidopterans, can be mass produced both in vivo, using the greater wax moth Galleria mellonella (L.) (Lepidoptera: Pyralidae) as a factitious host, and in vitro, on artificial media composed of crude components. The present study was focused on another aspect of E. larvarum rearing, namely the influence of adult food on parasitoid performance. The standard food, consisting of lump sucrose and cotton balls soaked in a honey and water solution (1), was compared with other foods or food combinations, namely lump sucrose alone (2), honey and water solution (3), sucrose and water solution either alone (4) or combined with bee-collected pollen (5), and, finally, pollen alone (6). All foods were provided together with distilled water supplied in drinking troughs. Based on the parameters considered (i.e., female longevity, number of eggs laid on host larvae, puparia obtained from eggs, and adults emerged from puparia), pollen alone was deemed to be the most suitable food for adult females of E. larvarum . In particular, the pollen showed a longevity-promoting effect, increasing the number of eggs laid on host larvae throughout the female lifespan. The use of this adult food may also result in a higher flexibility of the management of E. larvarum colonies because it can be replaced weekly, as no desiccation or mold infections were ever found to occur.
