It was formerly considered to be an important pest in coastal Kenya and Madagascar (Mathez 1972, Warui and Kuria 1983, Delobel 1975a), but its pest status has changed with the establishment of the exotic stemborer, C. partellus. Bulletin of Entomological Research 80, 363-368. In the southern coastal area of Kenya (0-500 m), C. partellus was by far the most abundant species in maize, sorghum, and two wild grasses, Sorghum arundinaceum, and Panicum maximum, typically accounting for > 80% of the stemborers collected.

Mbapila, J. and Overholt, W. A. Bulletin of the British Museum of Natural History, Entomology 25, 101-195. Coniesta ignefusalis Hampson (Pyralidae) is an important pest of millet in the Sahelian region of Africa (Nwanze 1991). C. flavipes responded more strongly to maize, while C. sesamiae exhibited a preference for sorghum (Ngi-Song et al.

This finding suggests that the population in Mauritius could be a distinct taxon, although interbreeding tests with other C. flavipes populations need to be conducted before reaching a final conclusion. C. flavipes was found at two locations, Tarime and Magu, which are both near Lake Victoria in the area bordering southwestern Kenya. Laboratory studies revealed that C. partellus, C. orichalcociliellus, and S. calamistis were acceptable and suitable hosts for parasitization by C. flavipes and C. sesamiae (Ngi-Song et al. Appl. (1993) Release of beneficial insects in Kenya. 1996). The apparent shift in the abundance of the two Chilo species during the recent past suggests that the exotic stemborer may be displacing the indigenous species. , Dimensions ICRSIAT Patancheru, India and CABI Oxon U.K. 84 p. Ingram W. R. (1958) The lepidopterous stalk-borers associated with Gramineae in Uganda. Both parasitoids responded more strongly to unwashed C. partellus larvae removed from maize stems than to larvae washed in distilled water after removal (Ngi-Song 1995), and in a dual choice test, C. flavipes responded more strongly to frass than to stemborers (Potting et al.

(Pyralidae) and the contribution of natural enemies to its mortality under intercropping system in Kenya. We controleren wel eerst of ie voldoet aan onze reviewvoorwaarden en niet nep is. These results suggest that if C. flavipes were to be released in areas where suitable and unsuitable occurred sympatrically, the parasitoid population would suffer mortality in the unsuitable hosts. This was quite surprising as no releases had been made in this area, and it is over 600 km from the coastal release sites. Overholt W. A., Ochieng J. O., Lammers P. and Ogedah K. (1994c) Rearing and field release methods for Cotesia flavipes Cameron (Hymenoptera: Braconidae), a parasitoid of tropical gramineous stem borers. He indicated that C. partellus was found in warmer regions and B. fusca in cooler areas. This book addresses the susceptibility of different larval instars; effect of temperature on fungal development and virulence; food consumption of fungus treated larvae; compatibility of fungal isolates with insecticides; effect of exposure methods and diets on larval mortality; and control of stem borer using effective isolates. (1970) An annotated list of the parasites of graminaceous stem borers in East Africa, with a discussion of their potential in biological control. University of Ghana, Legon. Based on evidence from surveys conducted prior to 1994 and on electrophoretic evidence, it was concluded that the most likely possibility was that C. flavipes escapted from a colony maintained at Mbita Point in 1991 (Omwega et al. The present paper reviews the studies that were conducted on C. flavipes at ICIPE prior to and after release in Kenya, and to provide evidence of its establishment in Kenya and in Tanzania. Parasitoids were released both as adults and as cocoons. (Lep., Noctuidae) on maize in the Coast Province, Kenya. Lees er meer over in ons cookiebeleid. B. fusca and E. saccharina were aceptable for ovipostion, but no parasitoid progeny developed to maturity in either host. is dag en nacht open. In its aboriginal home, C. flavipes has been reported to parasitize several gramineous stemborers. Studies on the host finding ability of the two parasitoids for aestivating and non-aestivating larvae revealed that neither parasitoid was capable of locating aestivating larvae in dried maize stems (Mbapila 1997). Thus, it appears that C. flavipes has a fairly wide host range. Bezorging dezelfde dag, 's avonds of in het weekend*, Ophalen bij een afhaalpunt mogelijk. Insect Sci. However, similar studies on competition need to be conducted using indigenous stemborers as hosts. (1960) The insect pests of graminaceous crops in East Africa.

Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. Thus, there is evidence of two biologically distinct populations of C. sesamiae; one that can develop in B. fusca, and one that cannot.

This release was conducted to determine whether C. flavipes could colonize the wild sorghum habitat and then move into a maize agroecosystem during the following rainy season. Warui C.

Host suitability of Africa gramineous stemborers for Cotesia flavipes1. C. flavipes is native to the Indo-Australian region, but has been widely introduced against various stemborers in the neotropics, several Indian Ocean Islands, and also been redistributed within Asia (Overholt et al. 1996). Mbapila J. (1978) The distribution and biology of Eldana saccharina Walker (Lepidoptera: Pyralidae) and its relationshiop to other stemborers in Uganda. Investigations on male-female attraction demonstrated that C. flavipes males were attracted to conspecfic females, but not to females of the other two species, suggesting that opportunities for interbreeding in nature would be rare (Kimani and Overholt 1995). 1995. Scheibelreiter G. K (1980) Sugar-cane stem borers (Lepidoptera: Pyralidae and Noctuidae) in Ghana. In an artificial laboratory setting, C. flavipes would parasitize aestivating larvae when the host and parasitoid were placed in close proximity. Entomological Society of Nigeria, Occasional Publication 29: 1-29. In summary, both parasitoids were attracted to volatile odours emanating from stemborers in grasses, regardless of whether the stemborer was a suitable host. Chemical control is often not successful because of the concealed feeding behavior of the insect. Because two or more stemborer species often occur sympatrically in Africa, it was important to determine the host range of C. flavipes prior to its release. Chilo partellus and C. orichalcociliellus populations are sustained during dry non-cropping periods through two mechanisms; aestivation as late instar larvae in crop refuse (Scheltes 1978), and as non-aestivating larvae in wild grasses (Delobel 1975b). The laboratory colony of C. sesamiae used for our host range studies originated from material collected in coastal Kenya, where B. fusca does not occur. : Zeitshrift fur Angewandte Entomologie 89, 87-99. Intensive surveys throughout the year are now being conducted at 3 locations in southwestern Kenya to more accurately measure stemborer mortality caused by C. flavipes. Cotesia flavipes was selected as the first candidate for introduction because of its history of success outside of Africa, and its importance as a parasitoid of stemborers in its aboriginal home (Overholt et al.

The results of the competition studies suggest that C. flavipes is a superior parasitoid when C. partellus is the host.

This book is useful especially to professionals in agriculture, biological and environmental sciences. Data from the 1996 long rains cropping season has not yet been completely analyzed, but the number of recoveries of C. flavipes increased dramatically and it was the most abundant parasitoid at 5 of the 11 sites it was recovered. Environmental Entomology 21, 1160-1167. Two indigenous species, C. orichalcociliellus and S. calamistis, also occurred. The developmental times of parasitoids in aestivating and non-aestivating larvae were not different, suggesting that the endocrine environment of the host did not induce diapause in C. flavipes (Mbapila, 1997). Applic. Chilo orichalcociliellus Strand occurs in the coastal area of East Africa at elevations < 600 m (Nye 1960). Several grasses not infested with stemborers proved to be attractive C. flavipes and C. sesamiae, but infested plants provoked a stronger response (Ngi-Song et al. Kfir R.
