“…Augmentative aerial releases of Braconidae parasitoids for controlling insect pests were successful in many cases (Sivinski et al 1996;Obrycki et al 1997;Montoya et al 2000). In our case we developed an "on-farm parasitoid rearing facility" from which the parasitoid escaped and parasitized MHM in millet fields in the Sahelian Region.…”

Biological control of the millet head miner Heliocheilus albipunctella in the Sahelian region by augmentative releases of the parasitoid wasp Habrobracon hebetor: effectiveness and farmers’ perceptions

On-farm augmentative releases of the parasitoid Habrobracon hebetor (Say) for controlling the millet head miner (MHM) Heliocheilus albipunctella (de Joannis) was experimented in Burkina Faso, Mali and Niger from 2007 to 2009. In addition, a survey of farmers' perceptions of insect pests, with particular focus on MHM, and the biological control program (BCP) was carried out. Our findings indicate a significant increase of MHM parasitization rate after the releases with up to 97% mortality. The survey on farmer's perceptions revealed a fair knowledge of the MHM and the ability of farmers to describe the pest and its damage. Farmers claimed that the biocontrol agent H. hebetor is effective and perceived a significant gain in grain yield due to this control strategy. Implications of these findings for a large extension of the MHM biocontrol program are discussed.

“…It involves the release of natural enemies, typically mass reared in an insectary, either to inoculate or inundate the target area of impact (Obrycki et al, 1997;Parrella et al, 1992;Ridgway, 1998). Inoculative releases involve relatively low numbers of natural enemies, typically when pest populations are low or at the beginning of a growth cycle or season.…”

“…Releases can be either inoculative or inundative (Daane et al, 2002;van Lenteren, 2003;Obrycki et al 1997;Van Driesche et al, 2008). The goal of augmentative releases is to suppress pests for an entire growing season.…”

“…Rather, it's the released individuals that provide the needed control (van Lenteren, 2003;Van Driesche et al, 2008). Factors that determine usefulness of augmentation programs include availability, quality, and effectiveness of mass-produced natural enemies (Daane et al, 1998;Leppla et al, 2004;Obrycki et al, 1997;Van Driesche et al, 2008;Grenier & De Clercq, 2003).…”

“…Evaluating potential predators for mass production requires an understanding of its biology (Obrycki et al 1997) and other characteristics such as feeding and hunting abilities (Daane et al, 1998) in order to use each species effectively. When evaluating biological control agents, it's recommended that the predator's biology is matched with that of the target pest (Daane et al, 1998) and the system for which it is intended (Obrycki et al 1997).…”

Survey of Phytoseiids (Acari: Phytoseiidae) on the Central Coast of California

samples of avocados, cherimoya, caneberry, grape, and strawberry from a combined total of 24 sites. The most diverse collection of phytoseiids was identified on grape with seven different genera and 12 different species followed by caneberry with 7 genera and 7 species. Strawberry was the least diverse with three genera and three different species.The most significant presence of type I and type II phytoseiids were located on caneberry and strawberry while avocado, cherimoya and grape were dominated by type IV species.Reasons for the difference in diversity could be attributed to the availability of preferred hosts, alternate food sources, and the effectiveness of augmentative releases and pesticide applications.
