“…The application of cypermethrin alone and sequential application of cypermethrin, Bt and neem oil significantly reduced aphid population as well as flower infestation, but cypermethrin applied alone was found to be the most effective in reducing aphid population and flower infestation. The present findings corroborate with Weaver et al (1997) who reported that the bio-pesticides and oils were subjected to simple chemical fractionation and had great potential for insect control. Yule and Srinivasan (2014) reported that B. thuringiensis followed by cypermethrin reduced 23-85% yard long bean pod damage by M. vitrata.…”

Present study evaluated the effect of sequential application of a bio-pesticide (Bacillus thuringiensis subsp. Kurstaki) (Bt), a botanical (neem oil) and a chemical insecticide (cypermethrin 25EC) as well as cypermethrin 25EC alone in the management of aphid (Aphis craccivora) and pod borer (Maruca vitrata) attacking yard long bean (Vigna unguiculata sesquipedalis) in the field. In each treatment Bt, neem oil and cypermethrin were applied in alternative sequence as well as cypermethrin alone at 07 days intervals. All the treatments reduced aphid population and flower infestation after 24, 48 and 72h of treatment compared to untreated control. Aphid population reduction by the treatments over control was ranged from 34.4 to 71.9%, and the treatment with cypermethrin alone had the lowest abundance of aphid and flower infestation. The Bt followed by neem oil and cypermethrin significantly reduced the pod infestation by pod borer and increased yield (38.9-41.4%) over control with BCR: 1.85-2.16. Use of cypermethrin alone was most effective and showed the lowest pod infestation and revealed the increased yield over control (47.7%) with BCR 4.70. Considering the hazardous affect of cypermethrin alone, its application followed by bio-pesticide and botanical sequentially would be promising components for integrated pest management strategies against aphid and pod borer attacking yard long bean.

“…Furthermore, T. minuta extracts have also been shown to significantly kill various kinds of insect pests such as stored product beetles (Weaver et al, 1994(Weaver et al, , 1997Keita et al, 2000), mosquitoes (Philogene et al, 1985;Basabose et al, 1997;Perich et al, 1995) and armyworms (Rao et al, 2000;Aldana-Llanos et al, 2012). Most of these studies further identified chemical substances that appear as likely candidates for active compounds responsible for effecting insect mortality.…”

The cabbage aphid, Brevicoryne brassicae is one of the most serious insect pests of cabbage in Lesotho. Chemical insecticides for efficient control of this pest are often unaffordable for resource-poor farmers. As a first step in a search for effective pest management techniques that can be affordable and easily available to these farmers, the aphicidal activities of Tagetes minuta crude extracts were evaluated against the cabbage aphid. A comparison was made on lethal and sub-lethal effects of T. minuta crude extracts from acetone, methanol, water and a mixture of acetone/methanol/water (7:7:1, v:v). The solvent system that produced the most toxic extract was the mixture, followed by methanol and water, whereas acetone produced the least toxic extract. The sub-lethal effect on cabbage aphid fecundity was well described by linear regression equations that showed significant reduction in fecundity as the concentration of crude extracts increased. The extract from the mixture solvent system had the strongest effect on fecundity.
