Exploring levels of egg parasitism and variation in egg cuticular chemistry in different Clavigralla spp.

Autor: Kpongbe, H. Berg, J. van den Khamis, F. Tamò, M. Talamas, E.J. Torto, B.

Clavigralla spp. (Hemiptera: Coreidae) are major pests of cowpea (Vigna unguiculata (L.) Walp, Fabacae), common bean (Phaseolus vulgaris L., Fabacae) and pigeon pea (Cajanus cajan L., Fabacae) in Africa. Clavigralla spp. egg parasitoids, Gryon spp. (Hymenoptera: Scelionidae), have previously been...

Management of cyst and root knot nematodes: a chemical ecology perspective

Autor: Torto, B. Cortada Gonzales, L. Murungi, L.K. Haukeland, S. Coyne, D.L.

Plant parasitic nematode infection of crops can be highly detrimental to agricultural production. Since the discovery that plant roots release chemicals that attract the infective stage of plant parasitic nematodes some 80 years ago, significant progress in identifying the signaling molecules has...

Identification of key root volatiles signaling preference of tomato over spinach by the Root Knot Nematode Meloidogyne incognita

Autor: Murungi, L.K. Kirwa, H. Coyne, D. Teal, P.E. Beck, J.J. Torto, B.

The root knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood, is a serious pest of tomato (Solanum lycopersicum) and spinach (Spinacea oleracea) in sub-Saharan Africa. In East Africa these two crops are economically important and are commonly intercropped by smallholder farmers. The ...

Application of superabsorbent polymers (SAP) as desiccants to dry maize and reduce aflatoxin contamination

Autor: Mbuge, D.O. Negrini, R. Nyakundi, L.O. Kuate, S.P. Bandyopadhyay, Ranajit Muiru, W.M. Torto, B. Mezzenga, R.

The ability of superabsorbent polymers (SAP) in drying maize and controlling aflatoxin contamination was studied under different temperatures, drying times and SAP-to-maize ratios. Temperature and drying time showed significant influence on the aflatoxin formation. SAP-to-maize ratios between 1:1...

Parasitic nematode Meloidogyne incognita interactions with different Capsicum annum cultivars reveal the chemical constituents modulating root herbivory

Autor: Kihika, R. Murungi, L.K. Coyne, D.L. Ng'ang'a, M. Hassanali, A. Teal, P.E.A. Torto, B.

Plant volatile signatures are often used as cues by herbivores to locate their preferred hosts. Here, we report on the volatile organic compounds used by the subterranean root-knot nematode (RKN) Meloidogyne incognita for host location. We compared responses of infective second stage juveniles (J...

Isopentyl butanoate: aggregation pheromone of the brown spiny bug, Clavigralla Tomentosicollis (hemiptera: coreidae), and kairomone for the egg parasitoid gryon sp. (hymenoptera: scelionidae)

Autor: Kpongbe, H. Berg, J. van den Khamis, F. Tamò, M. Torto, B.

The brown spiny bug, Clavigralla tomentosicollis Stål (Hemiptera: Coreidae) is a key pest of leguminous crops in many countries in Africa, causing significant yield losses especially in cowpea, pigeon pea and common beans. Although C. tomentosicollis uses olfaction to aggregate, little is known a...
