The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad.
The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966.
The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter.
Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

The present study entitled “Monitoring and Management of Cotton Pink Bollworm, Pectinophora gossypiella Saunders (Gelechiidae: Lepidoptera)” was carried out during 2018-19 and 2019- 20. The objectives are; to assess the incidence of pink bollworm in different cotton-growing regions of Andhra Pradesh, management of pink bollworm by mating disruption technique, assessment of the sources and carryover of PBW incidence during the offseason, studies on the screening F2 population of PBW for resistance alleles to Cry toxins, and molecular characterization of Andhra Pradesh Pink bollworm populations. The last two studies were done at Central Institute for Cotton Research (ICAR-CICR) Nagpur, Maharashtra.
The insect was recovered from all the 12 sampled locations. Significant differences were observed across the mandals and among different survey dates. In 2018-19 the average damage to flowers was 14.64% for all the 12 mandals of three districts. However, the boll damage recorded was 52.27%, with an average of 0.84 larvae/boll. The per cent locule damage recorded was 31.50%. Likewise, in 2019-20, the average flower damage recorded was 16.38% and boll damage was 53.62% with 0.86 larvae/boll. The per cent locule damage recorded was 34.19%.
Results obtained from the study of carryover mechanisms of pink bollworm in Andhra Pradesh revealed that in 2018-19, an average of 371.47 moths/trap/fortnight were trapped at ginning mills in the Guntur district. The fortnight interval catches ranged from 21.80 on 30th July to the maximum of 1237.80 on 30th March 2019. In 2019-20, an average of 466.0 moths/trap/fortnight were recovered. The fortnight interval catches ranged from 30 on 30th July to 1376 on 30th March 2020.
The studies on the role of ginning waste in the carryover of the pest were conducted during the offseason. From the collected sample of 10 kg of ginning waste, the average number of live larvae, pupae, and double seeds were 63.57, 21.35, and 18.64 in 2019 and 70.35, 24.42, 20.78 in 2020. The average male and female moths
were 57.71 and 85.71 in 2019 and 60.71 and 95 in 2020. The damage was 1.5 and 1.8 per cent on mesta, whereas on bhendi it was 2.7 and 3.5 per cent. It is indicated that the alternate host plants of the Malvaceae family are supporting this pest only to a limited extent, and most of the pest population is carried through seed cotton in ginning mills.
The frequency of Cry1Ac resistance alleles in PBW collected from Andhra Pradesh was estimated to be 0.082 with a 95% CI of 0.051 – 0.105, and the frequency of Cry2Ab resistance alleles was estimated to be 0.054 with a 95% CI of 0.029 – 0.077. We report a high frequency of Cry1Ac and Cry2Ab resistance alleles in the field population collected from Andhra Pradesh. A < 3% probability of missing a resistance allele in 66 lines screened for Cry1Ac and Cry2Ab resistance.
The descriptive statistics Haplotype (gene) diversity (Hd), Variance of Haplotype diversity, and Standard Deviation of Haplotype diversity were measured with DnaSP ver. 5.10.01 software in a phylogenetic study of P. gossypiella and found to be 0.853, 0.00283, and 0.053 respectively, suggesting that the entire population had a low degree of genetic diversity.
The per cent mating disruption results revealed that the treated plot moth catches ranged from 0.2 to 10.2 per trap per week, and the average moth catch was 3.55 moths/trap/week. In the control plot, moth catches ranged from 2.2 to 89.6 per trap per week, and the average was 40.82 moths per trap per week. Per cent disruption ranged from 81.8 to 99.0, and mean disruption was 91.3% in 2018-19. Similarly, in 2019-20 the treated plot moth catches ranged from 0.6 to 26.8 per trap per week, and the average moth catch was 8.3 moths /trap/week. In control, plot moth catches ranged from 3.6 to 90.1 per trap per week, and the average was 51.9 moths per trap per week. Per cent disruption ranged from 70.3 to 96.8, and mean disruption was 84.1%.

Studies on “Evaluation of certain cotton genotypes against leafhopper,
Amrasca devastans Dist. (Hemiptera: Cicadellidae) and its management through ecofriendly
approach” were undertaken during Kharif, 2016-2017 at Regional
Agricultural Research Station, Lam, Guntur.
Fourteen cotton genotypes including one susceptible check were selected for
screening against leafhoppers and replicated twice in a simple Randomized Block
Design. The evaluation of different cotton genotypes against leafhopper under field
conditions revealed that, among all the genotypes, GISV-267 was resistant against
leafhoppers by recording the lowest damage injury index level (1.0-1.5 per cent )
harbouring mean population of only 5.3/3 leaves/plant and also recorded the highest
yield (18.5 q/ha). GSHV-173 genotype was also found promising with low leafhopper
population together with high yield.
Morphological and biochemical characters were studied for fourteen cotton
genotypes to asses the characters associated with tolerance or resistance to
leafhoppers. The study revealed that the genotypes with the highest hair density in
leaf lamina and midrib had exhibited the lowest leafhopper injury index and proved as
resistant genotypes against leafhoppers. The genotypes with higher quantity of
biochemical components such as tannins and phenols both at vegetative stage and
reproductive stage showed resistance or tolerance against leafhoppers.
The experiment for management of leafhoppers through eco friendly approach
was carried out in Randomized Block Design with seven treatments along with
control which were replicated thrice. Two each of botanicals, entomopathogens and
inorganic insecticides evaluated against leafhoppers infesting cotton. Among all the
treatments, thiacloprid + flubendiamide 480 SC was proved as significantly superior
over the other treatments in suppressing the leafhopper population both at 3 and 7
days after treatment by recording the highest reduction over control. The other
treatments in the order of efficacy in suppressing the leafhopper population are
thiacloprid 48 SC and azadirachitin 10000 ppm with more than 50 per cent reduction
in leafhopper population over untreated control.The entomopathogens Lecanicillium
lecani and Beauveria bassiana had exerted comparatively less efficacy in suppressing
the leafhopper population when compared to botanicals and inorganic insecticides.
Natural enemy population was more in the entomopathogens and botanical based
treatments which were found to be on par with control plots. The seed cotton yield
was highest from thiacloprid + flubendiamide 480 SC @ 0.4 ml / l (18.98 q / ha) but it
was found on par with thiacloprid 48 SC 0.3 ml / l (18.80 q / ha.) and azadirachitin
10000 ppm @ 1.5 ml / l (17.62 q / ha).
