The effects of powdered herbs (lavender Lavandula officinalis L., peppermint Mentha piperita L. and basil Ocimium basilicum L.) added to the food substances of three insect species: the rice weevil Sitophilus oryzae (L.), lesser grain borer Rhyzopertha dominica (F.), and the saw-toothed grain beetle Oryzaephilus surinamensis (L.) on the life span and development of the three insect species as well as habitat conditions, sex structure, and the survivability of males and females were considered. The experiments were conducted in the laboratory at a temperature of 28°C and relative humidity (RH) 60 ±5%. In all the studied populations, high female mortality was found (♂/♀ < 1). The studied populations were: the rice weevil and the lesser grain borer cultured in wheat grain with herb additions, and the saw-toothed grain beetle cultured in semolina with herb additions. Among the herbs used, peppermint caused a significant effect in the form of increased mortality rates among females of S. oryzae and O. surinamensis. Lavender and basil had a similar impact among R. dominica females. The herbs applied in the experiments intensified the mortality of females and, consequently, led to the disappearance of entire populations.

This study investigated insect pest infestation of maize, millet, sorghum, rice and wheat grains traded in the three main markets namely Monday, Baga-Road and Custom-Park markets in Maiduguri, Borno state, Nigeria. Sampling lasted from January to June 2012. Samples per grain type, each weighing one kilogram, were obtained every two weeks from ten randomly selected traders per market. Each sample was sieved in the laboratory to recover all adult insects present, both at sampling and also after one month stay (laid out in a completely randomized design). In each market, Sitophilus zeamais Motschulsky and Rhyzopertha dominica (F.) followed by Tribolium castaneum Herbst, Sitophilus oryzae (Linnaeus), Trogoderma granarium (Everts) or Cryptolestes sp. were the insect pests commonly found attacking more (between two to five) grain types. Observed highest and lowest mean insect numbers were respectively by S. zeamais in maize grains (12.13 individuals in Monday market) and T. granarium in wheat grains (0.13 individuals in Baga-Road market). Results unveil that among three markets, higher mean total numbers of insects were present in maize, rice or wheat (18-33). For all grain types, the mean numbers of damaged grains were significantly higher in Monday (53-357) and Custom-Park (46-302) than in Baga-Road (17-109) markets. Furthermore, the mean total number of damaged grains across markets was significantly higher maize, followed by rice and wheat (55-231) than in other grain types (37-41). The implications of all these results on insect infestation of different cereal grain types sold in these markets are discussed.

Plant secondary metabolites play an important role in plant-insect interactions and therefore such compounds may have insecticidal activity against insects. The chemical composition of the essential oil from leaves and flowers of Lavandula stoechas grown in Kashan, Iran, was studied by gas chromatography mass spectrometry (GC-MS). 1,8-Cineole (7.02%), γ-Cadinene (5.33%), T-Cadinol (5.07%), p-Mentha-1-en-8-ol (5.02%) and Caryophyllene (5.01%) were found to be the major constituents of the oil. In fumigant toxicity tests with the essential oil against adults of Tribolium castaneum Herbst, Lasioderma serricorne F. and Rhyzopertha dominica F. at 27±1°C and 60±5% RH, it was observed that L. serricorne (LC50 = 3.835 μl/l) were significantly more susceptible than R. dominica (LC50 = 5.66 μl/l) and T. castaneum (LC50 = 39.685 μl/l) 24 h after treatment. In all cases, considerable differences in mortality of insects to essential oil vapor were observed with different concentrations and times. Mortality increased as the doses of essential oils and exposure period increased and after 72 h fumigations, greatest percentages of mortality were obtained. The findings indicate the strong insecticidal activity of L. stoechas oil and it may be used in grain storage against insects L. serricorne, R. dominica and T. castaneum.
