Intra- and interpopulation correlations between productivity and period of productivity were significant. One-day-old pupae and one-day-old adult weights were not associated with productivity. The intrapopulation correlation coefficients between productivity and developmental time were found to be significant. However, all of them (except one) were negative. Significant interpopulation relationships were noted when productivity was correlated with 13-day larval weight and with developmental time. Positive and negative correlations were found between productivity-larval weight and productivity-developmental time, respectively. It is concluded that developmental time is the most important factor in controlling productivity in T. castaneum under the constant conditions of the present investigation.

The impact of antenatal counselling on couples’ knowledge and practice of contraception was investigated. An interview questionnaire was used before and after conducting counselling sessions with 200 pregnant women and 100 spouses. The participants were followed up immediately after delivery and 3 months later. Both the control and study groups displayed a lack of knowledge of contraception. Counselling sessions improved the couples’ knowledge and practice in the study group. Involving husbands in family planning counselling sessions led to joint decisions being made and encouraged women’s use of contraception. The majority of couples retained most of the information given. Integrating family planning counselling into antenatal care in all facilities and involving the husband are recommended

The efficiency of boric acid, borax and imidacloprid is evaluated for inhibition of adult house fly emergence (IC values) as dry and liquid baits. In the two cases, imidacloprid has the greatest fatal effect at both IC 50 and IC 90 levels followed by boric acid and then borax. In the liquid formulation, IC 50 and IC 90 values are (0.083 and 2.6%), (0.19 and 2.48%) and (2.6 and 16.9%) for three tested compounds respectively. The relative efficiency for imidacloprid and boric acid compared to borax (the least potent one), imidacloprid and boric acid achieved 31.3 and 13.7 times more suppression of adult emergence than borax. In the solid formulation, IC 50 and IC 90 values are (0.083 -0.67%) followed by boric acid (3.7-11.6%) and borax (5.74-21.1%) respectively. It's clear that imidacloprid 68.8 times and boric acid 1.5 times as toxic as borax. Reasons for differences in manifestation of mortality and possibilities for practical application are discussed. We conclude that the efficiency of tested compounds as liquid baits is higher than it as dry baits.
